With the overwhelming coverage of the media on electric vehicles, electric vehicle market in China seems to begin to take off - the vast majority of mainstream car manufacturers are actively developing electric cars, the Government also provides a strong policy and financial support. However, the electric vehicle market could soon start? This will depend on many factors, one of the key is the charging infrastructure.
Most electric vehicles rely on the slow charge pile at home or work place near to meet the charging needs, is an accepted fact. However, the booming market of electric vehicles depends on a convenient and rapid solution, there are two options, replace the laptop battery and fast charging. Auto manufacturers, battery manufacturers, power grids, service providers and consumers have different preferences and interests lie. The game will be between the two options for the future development of electric vehicle industry in China have a significant impact. Many Chinese local automobile manufacturers support the replacement of the battery, because it makes them without in-depth understanding of integrated battery technology quickly to market low-cost electric vehicles. In order to protect their business efficiency and economic interests, China's two power grid companies have become powerful agents of change for the acer battery replacement mode. Early electric car buyers may be attracted by its low purchase price, and without regard to the potential life of lithium.
Therefore, the battery replacement is more likely to become the dominant mode of the quick service. Faced with such a development trend, market participants must re-adjust their electric vehicles and ancillary charge strategy. International automobile manufacturers in particular, need to make a choice to follow the global electric vehicle development strategy in China, or take a special treat for the Chinese market. Service providers need to think about how to effectively control the risk of instability of dell battery technology development while providing the best customer experience, innovative business model is one of the key.
Government policies need to ensure that the necessary charging infrastructure is in place, while in the service sector to promote open competition in the market. Particularly important for emerging markets can learn from developed countries, there is no mature business model, with an open mind.
The development of electric vehicles in China
The electric vehicle market in China is evolving, but for many people was not quick enough. Leap forward in this industry seems to power, it will really achieve?
The Chinese government for the purpose of reducing oil dependence and emissions, and provides a strong financial incentive grant program for electric vehicles, and has developed a goal to become the world's leading electric vehicle hp laptop battery development country and the country of manufacture, electric vehicles also among the seven strategic emerging industries. Chinese parties are best for electric vehicles: the car manufacturers have received state aid, while state-owned power grid companies and the oil companies are also urged to establish a charging facilities network as soon as possible.
The automobile manufacturers have been a lot of R & D and production work, among the relevant science and technology are making progress. Whether foreign or domestic mainstream car manufacturers are ready to be released within the next few years, the new pure electric or plug-in hybrid.
This booming trend in the strong government subsidies, another contributing important factor is the continued progress of notebook battery technology. Battery energy density in the end of 2011 is expected to reach 150 Wh / kg to 500Wh/kg 2020 will cost from $ 750 / kWh down to $ 150 / kWh. This will enable automobile manufacturers were able to effectively to quickly lower the price of pure electric vehicles and plug-in hybrid vehicles, increase market acceptance.
July 2011 issued by the Ministry of Science and Technology on the electric car "12" special planning to establish a "12" during a pure electric vehicle technology in a small passenger car route, and the establishment of electric vehicle ownership in 2015 to achieve the goal of 1 million. Kearney forecast in China, sales of electric vehicles will climb in the next two to three years, the cumulative total sales of electric vehicles is expected to reach 85 million units in 2015 to 2020 about 500 million units. Most electric vehicles will be used for a second vehicle for private cars and commercial vehicles.
All the trends are clear, but there are still a major obstacle need to be overcome: the establishment of charging facilities.
About to start charging infrastructure markets
Kearney survey shows that most people can rely on the slow charging facilities, but the deployment of rapid public charging facilities is the key to break the electric vehicle to accept obstacles, shown in Figure 1. Different types of charging facilities must demand the coordination of the layout, in order to effectively promote the development of the electric vehicle market.
Excitation of the government policies to promote long-term market opportunities, state-owned power grid companies and the oil companies into action. By the end of 2010, about 76 fast charge / replace the Laptop Battery for Dell XPS M1730 station with more than 6500 charging pile operations.
- National Grid is currently charging facilities market leader. After years of discussion, the State Grid has developed a plug charge "for power generation, supplemented by centralized charging uniform distribution of the mode of operation. Expected in 2020, the State Grid plans to build 10,075 battery replacement stations with a total investment of 32.3 billion yuan, and 500 000 charging piles with a total investment of 12.5 billion yuan.
- China Southern Power Grid has also started construction in Shenzhen, Guangzhou, Nanning and Kunming, about 10 charging stations and 350 charging pile. China Southern Power Grid has the main push of fast charging stations, to change strategy in early 2011, however, contract with the Better Place battery replacement stations established within the service area. The contract agreement in Guangzhou in 2011 years a Battery for APPLE A1175 replacement station and Experience Center, and will work together to set up a joint venture. The joint venture will become the entry point of the Better Place in the Chinese market.
With the existing network of petrol stations, oil companies are also actively seeking to enter this market.
- Sinopec Beijing branch has been established with the First Division Group of the first subjects of the joint venture in petrochemical New Energy Technology Co., Ltd.. This joint venture will focus on the transformation of existing gas stations, integrated battery charging service. Sinopec also consider battery replacement in the future to carry out business. Overall, Sinopec's goal is to establish an integrated refueling charge service stations.
- In addition, CNOOC Tianjin Lishen Battery invest 5 billion yuan, the construction of a joint venture in Shenzhen and Hangzhou and charging stations.
However, due to potential conflicts of interest, the efforts of the oil companies are often subject to the constraints of the power grid companies.
Slow charging network: consensus
Electric vehicles almost every day needs to be charged. Therefore, the easiest way to deploy charging facilities in locations convenient to the owners, such as the family garage, public parking, workplace parking lots.
Kearney's survey shows that a typical consumer can rely on to meet the daily needs of nearby charging pile, shown in Figure 2. This is recognized by the auto manufacturers, camera battery manufacturers, service providers, power grids and consumers, including the parties.
Personal charge pile of practical significance for the electric vehicle owners to have a private garage. Electric car owners for private or fixed parking spaces, should be actively planning the public slowly filling facilities located near residential areas and work units. Since most of China's electric vehicle owners will focus on the district live in cities, this part of the planning is particularly important.
Kearney forecast China slow charge pile the total number expected to reach 4.7 million by 2020, an average annual compound growth rate of 103%, shown in Figure 3.
The remaining question is who will be the construction and operation of these facilities. Kearney think that the grid is the most suitable candidates for the main building. According to the Electricity Law of the People's Republic of China, only the grid to allow the sale of electricity, if the regulations is not adjusted, the involvement of other service providers will be greatly hindered. Due to slow charge pile construction may need to be near distribution facilities expansion, without the active cooperation of the Grid Corporation of difficult to implement.
Charge pile local construction needs in the district, parking, business center, the grid company must also cooperate with the property management department of the above locations or property owners, jointly operated trickle charge pile. Property managers, owners, or local government for charging facilities remain designated a specific area, to assist the day-to-day maintenance, and revenue sharing.
Each slow charge pile is currently consuming about 8000 yuan, can be filled with an electric car in about four to the eight hours. In Shenzhen has been the implementation of the rules, for example, Grid Corporation of commercial electricity rates for charging service billing, successive charges. Consider the income of the public charging pile, in Figure 4, assume the grid electricity cost is 85% of the retail price of the period distribution of user charging for off-peak hours at night to 30% and 70%, the daily peak hours, and the slow charge pile The overall utilization rate has increased annually, the average annual income is shown in Figure 5 shows, the total cost of recovery can be completed in six to eight years.
Fast charging and battery replacement choice: the smoke is from the
Quick service network represents a more competitive market, which is where most of the focus of debate and positions of contention.
The main intention of consumers to buy electric vehicles daily traffic, but each owner from time to time over the weekend to the outskirts of travel to distant lands, or to visit far away friends and relatives. Even if some car owners do not need such long-distance travel, they would still worry about stranded because they can not charge it in time, this is the so-called "range anxiety". Therefore, rapid public charging network is essential for the development of electric vehicles.
Reference to the number of petrol filling stations in China and penetrate the potential market for electric vehicles, AT Kearney expects 2020 the whole territory of about 15,000 quick service stations, including fast charging stations and battery replacement stations, the compound annual growth rate 72%, shown in Figure 5.
A. two choices: fast charging and battery replacement
Fast service can be done by the fast charging or battery replacement. Fast charging compared with the trickle charge to use a higher voltage and higher current, 80% of the battery charging can be completed in less than half an hour. Cancorder Battery replacement is the use of a sophisticated automated system to rapidly replace the depleted battery, the battery is fully within five minutes, and after battery cooling and charging work in the background.
The fast charge is the more traditional options, and can be more easily understood by consumers, because it uses a very similar business models and traditional gas stations. Can be used in the billing, pay-per-view or use the service pack in two ways. The key to its success include the establishment of the communication protocol between the unified jack standard battery with the power grid. However, if the effective temperature, fast charging can cause great harm to the ACER Aspire 4736Z Laptop Battery, reducing battery life.
In contrast, the battery replacement is more rapid solution, can be completed within 5 minutes. Take into account the weight and technical features of the battery, battery replacement methods and the professionalism of the staff requirements higher. It uses a more complex business model based on the battery lease: the service providers to buy and have the battery, With these battery replacement service, consumers do not buy any batteries in the purchase of bare car. Consumers can buy based on monthly mileage service pack, and a monthly fee. The key to its success is unified between the different models of battery standards. Therefore, this market by battery manufacturers, automobile manufacturers and service providers to jointly promote.
The two business models have been pilot applications in different markets in the world. Better Place Denmark and Israel, Battery Acer Aspire 5530 Replacement pilot project. At the same time, the Coulomb Technologies is a rapid charging facilities network.
These two models will form a completely different business model, far-reaching implications for the entire electric vehicle industry. Both the final outcome of the game there are still large uncertainties, but there has been some progress: the relevant consultation already in progress, different strategies have been designed, and government lobbying activities is also carried out.
The future of electric vehicles, public fast service facilities in the end going? To answer this question, we have to charge electric vehicles ecosystem analysis and understanding of the key role of strategic intent.
B. interests of the Great Game: how the preference
Businesses and consumers to have their own interests lie, and to defend the interests through a series of marketing campaigns or lobbying activities. To predict the future of electric vehicle charging facilities, we must understand their foothold where. The value chain of the electric vehicle charging facilities covered by the ACER Aspire 8730Z Battery manufacturers, electric vehicle manufacturers, Power Grid Corporation, charging service providers and consumers of different roles, as shown in Figure 6.
(1) electric car manufacturers and battery manufacturers
Car manufacturers and battery manufacturers are divided on the fast charging and battery replacement. Their choice depends primarily on their technical level as well as their overall strategy (cost-driven and performance-driven).
Most of the international automobile manufacturers support fast charging. They are convinced that the power system technology is the embodiment of the core competitiveness, and to ensure that their pricing power in the market. These automobile manufacturers hope to launch as many as possible differences in products, to ensure maximum profits. They are usually in close cooperation with ACER TravelMate C210 battery manufacturers or integrators. One example is the BMW cooperation with SBLimotive (Samsung and Bosch joint venture), the use of distributed battery weight and balance technology provides a superior driving performance. Similar cooperation is also seen with Magna, Ford and LG Chem of GM Compact Power (LG), and Toyota with Panasonic (electric vehicles, energy). These automobile manufacturers committed to give full play to the vertical integration of technology and capacity of the battery manufacturer. Through this strategy, they can ensure that their technological competitiveness, and as soon as possible to release models with exclusive battery technology.

How to make laptop longevity notebook battery maintenance skills
For notebook performance and functionality, vendors are constantly developed powerful laptop system stability, the design of the hardware, but also more humane, but one expensive laptop, the battery performance and use is often overlooked user when the battery when the use to care about their use and maintenance problems. In fact, the use of laptop battery should be strengthened more use of the concept, we will not spend more money trying to buy a new battery. To make the books of the main people can better understand all aspects of dell laptop batteries, the author's own experience in this to share with you. After all, the price of laptop battery is still very expensive, accounting for the overall price of the notebook for 10% -15%, the battery can be considered consumer goods, with a good battery is equivalent to saving money.
Laptop Battery
The type of laptop battery and materials:
Laptop battery is divided into four categories: 1. NiCad battery [Ni-Cd Ni-Cd], 2. Nickel metal hydride batteries [Ni-MH Ni-MH], 3. Lithium batteries [lithium Li, Li-ion Li-ion, Polymer lithium secondary Li-polymer], 4. fuel cell [Alkaline FC (AFC), phosphoric acid FC (PAFC), molten carbonate FC (MCFC), solid oxide FC (SOFC) and proton exchange membrane FC ( PEMFC), etc.]
Nickel-cadmium batteries (Ni-Cd)
The first notebook to use nickel-cadmium batteries are (Ni-Cd), because HP Compaq Business Notebook 6710b Battery technology was not advanced enough, so nickel-cadmium batteries have many shortcomings of headaches, such as: bulky, heavy weight, small size, short life, there memory effect, etc. (My impression is that no one place). These are undoubtedly pursued with the notebook's lightweight, fast performance of the contrary. The current nickel-cadmium batteries have been eliminated, and nickel-cadmium notebook also break, and mention it there is not much need.
Nickel-metal hydride battery (Ni-MH)
Ni-MH battery is the most environmentally friendly battery, environmentally friendly countries are vigorously promoting the use of nickel-metal hydride batteries, as easy to recycle, and damage to the environment is minimal. However, compared to nickel-metal hydride batteries and lithium, there are some drawbacks. Long charging time, the weight of a more sedate, small capacity than lithium, as well as the memory effect. It's memory nickel-cadmium batteries, although not as big, but still need to discharge, the user must be exhausted before charging. However, nickel-metal hydride rechargeable ACER Aspire 5715Z battery can reach more than 700 times, some good quality products up to 1200 times charge-discharge, long life than lithium is also very popular and the price.
Lithium battery (Li), lithium-ion battery (Li-ion), lithium polymer rechargeable lithium-ion battery (Li-polymer)
Lithium
Lithium a long time ago, when it was not safe when used often in charge when burning, bursting, perhaps because lithium is too active reason. Then there is the improved lithium-ion hp compaq 6710b battery (Li-ion) by adding the element lithium can inhibit the active ingredient, which is the alternative to lithium batteries, its possession of anode lithium ion can absorb the carbon pole, discharge, lithium into lithium-ion, from the anode, lithium-ion battery cathode reach. Charge, the ionization of lithium atoms into the cathode in lithium-ion and electron and ion movement to the anode and electronic synthesis of lithium atoms. Discharge, the lithium atoms from graphite crystals into a lithium anode surface ionization ion and electron, and the synthesis of lithium atoms in the cathode. Therefore, the lithium battery is always there to form lithium-ion does not appear to form lithium, of course, there will be no burning, explosion. Lithium ion moves between the anode and cathode, the electrode itself does not change. This is a lithium-ion batteries and lithium batteries difference in the nature. So that lithium really achieve a safe, efficient, convenient, and the old lithium also will be eliminated. Distinguish their approach is quite simple: from the battery of the label can be identified, the identity of lithium as Li, the lithium-ion battery Li-ion.
Lithium polymer rechargeable lithium-ion battery (Li-polymer) is that the three main structures in at least one or more polymer materials used as the main battery system. In shape, the polymer lithium secondary batteries with lithium ion can be thin, then it can be any area of any shape with a number of other advantages, it can meet the demand, made of any shape and capacity of the Dell xps m1330 battery. In thickness, the thickness of polymer lithium secondary battery is about 2 ~ 4mm, and the current lithium-ion battery is a minimum thickness of 6mm, can be reduced by at least 50% of the thickness, can reach the minimum thickness of about 0.5mm.
Now, laptops and mobile phones using the so-called lithium, in fact, lithium-ion battery. Battery lithium-ion batteries can not be compared with other advantages: high voltage; small size, light weight, high energy; safe and fast charging; allows a wide temperature range; discharge current is small, a small memory effect (now some view is that lithium-ion battery completely no memory effect, which is a not responsible for the view), no environmental pollution and so on. Of course, lithium-ion Dell vostro 1400 batteries also have their own shortcomings, that is, the price is high, fewer charge (charge and discharge times it is only 400-600 times, specially modified products, but 800 times. Charge a per day basis, the best The lithium battery also, but it laid off more than two years.), and battery-free interchangeability, voltage changes, the discharge rate of large, rapid decline in capacity, not high-current discharge.
Fuel cell
Fuel cell
Fuel cell [Alkaline FC (AFC), phosphoric acid FC (PAFC), molten carbonate FC (MCFC), solid oxide FC (SOFC) and proton exchange membrane FC (PEMFC), etc.] is a chemical battery, which uses released when the chemical reaction energy directly to electrical energy conversion. From this point of view, it and other chemicals such as manganese dry cell batteries, lead batteries, etc. are similar. However, it needs work to its continuous supply of active substances (substances that react) - fuel and oxidizer, which in turn, and quite different from other ordinary chemical batteries. Because it is the fuel energy released by chemical reaction into electrical energy output, so called fuel cells.
Fuel cell consists of three main components: the fuel electrode (anode); electrolyte (what we call the "fuel"); air / oxygen electrode (cathode). Initially, the electrolyte plate is the use of electrolyte into the porous plate to form, now being developed for the direct use of solid electrolytes. Work to the negative supply of fuel (hydrogen), the supply of oxidant to the cathode (air). Broken down into hydrogen ions in the negative H + and e-e-. Hydrogen ions into the electrolyte, while electrons towards the anode along the external circuit. Connected to the electricity load on the external circuit. In the cathode, the oxygen in the air with hydrogen ions in the electrolyte absorption arrived cathode electronic form on the water. This is the reverse reaction of water electrolysis process. Using this principle, the fuel cell can work continuously in the external transmission of Dell laptop battery at work, by the external supply of fuel and oxidizer. Therefore, in principle, continue to enter as long as the reactants, reaction products continuously excluded, fuel cells can continuously discharge. Both the non-polluting fuel cells, high efficiency, wide application, with no noise and the advantages of continuous work, the work product of the fuel cell only water and heat, no noise, the basic non-polluting, efficient power generation system than the general is much higher, reach 43 ~ 58%, if the use of heat produced by the reaction, the efficiency can be up to 80%! On the other hand is worthy of improvement, fuel cell cost is too high (low temperature fuel cell is used to generate the hydrogen required for expensive platinum catalyst, to obtain the cost per unit energy than lithium batteries), by-products, heat issues, and added access to fuel. These are to be further addressed in future issues, but it is the future of laptop batteries painted a bright future.
So for the current battery,
Battery selection is not perfect. Requirements for different users can choose according to their needs the appropriate type of battery, of course, notebook manufacturers are also make great efforts to develop more powerful and more portable battery.
Lithium ion battery
Since appearing on the market penetration rate is now the highest lithium ion battery (Li-ion) Therefore, this article will focus on lithium-ion batteries. Know your acer laptop battery you need to understand the following parameters: battery capacity, rated voltage, the normal use temperature.
Capacity, mainly from the size of the marked mAh battery to determine its Chinese name is ma. MA when the size is directly related to the use of laptop battery time, but it can not be generalized. Not to say that the greater the capacity laptop battery more sustainable supply and use, in the actual process of using endurance are closely related to the notebook's power consumption. We can imagine a laptop configuration, the greater the higher the energy, the greater the amount of computing power to run the faster passage.
Normal operating temperature is the temperature of the battery can work scope, the use of non-normal temperatures may be hazardous (explosive), and unnecessary trouble (leakage, a power outage).
Production date, which in some older models of laptop battery will appear, it is a direct reflection of this battery you can use the length of time, which is to determine the normal use of a battery time is very important parameter. So when we buy a apple laptop battery to pay attention to its production date, even if the new battery put his life a long time there will be a corresponding reduction. For users who want to buy second-hand books should be aware of the aspects is the parameter.
How to distinguish whether the battery parameters? From the above picture we can see the type of battery used for the Li-ion, that is, lithium-ion batteries. Rated output voltage of 10.8V, battery is 4800mAh. Of course, there are manufacturers, production, the normal operating temperature (0 degrees -60 degrees Celsius), at present, the identity of such batteries are used, we can enlarge the image above to understand their own laptop battery some basic information.
The external structure of the battery for the books we can take a look at some of the above parameters, the internal structure, I believe many people are "afraid" to understand. After all, the price of laptop battery is still regarded as expensive.
In fact, the nature of laptop batteries and ordinary rechargeable batteries no different kind, but the major manufacturers have their own models for the appearance of the battery case processing, so that if you peel the shell laptop battery, its internal structure and common There is no difference between the battery pack, that mutual constraints common major brand toshiba laptop batteries notebook computer is the greatest obstacle between the major brands of independent design.
The internal structure of the battery
The internal structure of the battery
A closer look at the internal battery, this battery is actually several groups of series-parallel circuit, in general, by a single battery notebook battery capacity and voltage requirements of the constraints, notebook batteries commonly used in parallel after the first series of measures to ensure its voltage and battery capacity, analogy, if a nominal 12.5V, 4000MAh laptop battery, generally so constituted: the first by three single-voltage 4.2V, 2000MAh batteries in series to achieve the standard 12.5V is known, then a group composed of the same cell and then parallel circuit, the battery's overall capacity to upgrade to 4000MAh, this battery is generally referred to 6CELL battery pack.
Six-cell battery
For internal and external laptop battery and power supply have a certain understanding of the principle, we can be better in their daily work, the use of laptop battery life. Then I talk about himself in the use of batteries for notebook computers, some experience and recommendations.
First, get a new battery, many users of the approach is in accordance with business tips in lithium batteries used in the first three charge 12 hours or more. Online there are a lot of controversy on this, but I found that in actual use, in fact, for most laptop batteries is not necessary. Why? Merchant said this is the activity in order to fully activate the battery, fully wake up a new battery. For this reason it sounds very full and reliable, but we have not thought about it. If the hp laptop battery manufacturers have not yet been fully activated on the appearance, then this can be said that only a semi-finished products. Not require each user to activate the battery to master the skills, in reality, impossible. Therefore, the battery factory has been a manufacturer of fully activated. Then ask the user to charge 12 hours will help the battery to use? In this I give a negative answer, the current laptop battery has improved power management circuits and charging management system, when the battery reached saturation, the control circuit automatically switches to short-circuit state, so the time is just after a waste of time only. How to activate the activity of the battery it? In fact, the activation of the battery manufacturer for overload protection in case there is no long the battery charge and discharge. Therefore, the first three charge 12 hours is unnecessary.
In time, many users use the battery very confused, what should or should not wait until the battery is completely discharged before charging. In fact, answering this question should be like, if you can do is certainly a good thing, but only if you took the trouble. Of course, I have here said is not referring to over-discharge, over-discharge is absolutely proven harmful to the battery, it will shorten battery life. Therefore, low power consumption when the notebook tips when you can charge a timely manner. Some businesses have repeatedly declared their lithium dell inspiron e1705 battery have no memory effect, this is extremely irresponsible. So when you have more power when the battery or not charging as well, because the memory effect does exist.
Third, for how long the battery should not do, it is recommended into the 40-50% of the electricity, placed in the cold shade, the following parameters can explain the problem.
Storage temperature of 40% state of charge 100% state of charge
0 98% (a year later) 94% (one year)
25 degrees 96% (after one year) 80% (one year)
40 degrees 85% (a year later) 65% (one year)
60 degrees 75% (a year later) 60% (3 months)
(Percentage of saturation at the time relative to the initial value)
Of course, the best month to take the battery out with time, both to ensure the battery is a good state of preservation, they will not let the loss of damage to the battery power completely.
Fourth, in the notebook computer for use in "a month later should use a full charge and discharge" approach is necessary. Notebook computer lithium-ion hp elitebook 6930p battery are generally charged with the management chip and control chip. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values. These values are in use will gradually change. Personally, I think, for use in notebook computers in "one month after the full charge and discharge should be a" major role in the practice is to fix these registers should be in the wrong value, making the battery charge control and battery nominal capacity consistent the actual situation. So this kind of work or can not be omitted, after all, expensive laptop or squeamish nobility.
The last to talk with, how to make the battery longer books. Since you bought a laptop is to use it, the battery is one of a consumable, with the use of an extension of time will inevitably move towards retirement. How to make sony laptop battery last longer? Power-saving technology? Sleep? Suspend to disk? To reduce the screen brightness? All these methods seem to be able to increase the so-called extended. But you have not thought of, such extended sense? I drove my books do not run any program, not open display, not to hard to switch, I can not achieve longer. May think this ridiculous practice, use of laptop is used, not sounding furnishings. Thus I suggest that you make good use of this and not care about how to use laptop notebook. Perhaps, after two years of the notebook market is another world, your books have reached the retirement ranks. As long as we pay attention to the battery's daily habits, the normal use of the battery can, they can do no need to over-cautious.
