“Our R & D vehicle prototype fuel battery hydrogen level, the higher performance can be said that the international advanced level, compared to a leader in the international level, there is a big difference.” Professor Wang Binggang that “it is a more objective evaluation.”Wang is a national clean vehicles Coordinating Action Group leader of the group of experts, the 863 Program,” energy saving and new VGP-BPS9/B VGP-BPS10 energy vehicles, “the office of leading experts in projects of ’scale.

“Energy saving and new energy vehicles” office of major project is the Ministry of Science and Hi-Tech Division (863 modern communication technology, office) under the jurisdiction of bodies of project management.

Ultra-billion yuan from the fund of the State Development to help stimulate the domestic manufacturers are scrambling to join the ranks of the hydrogen fuel battery research vehicle.

In addition to SAIC, Chery, etc. in the “Tenth Five-time” Year of the companies involved in research and development, Foton join too. In addition to SAIC’s field of cars to hydrogen fuel battery in the passenger area.

The main board short – life of hydrogen fuel batteries

In hydrogen fuel battery R & D car to Roewe 750 based on the “car fuel battery Shanghai” brand in China has developed the fourth generation of cars to hydrogen fuel battery, China represents the most advanced level. Of its supply system of fuel PB991A PB992A batteries in hydrogen fuel battery Shanghai Vehicle Power System Co., Ltd. Development.

And third vehicle energy production of batteries “Beyond the Three” from “Shanghai” brand fuel battery sedan vehicle dynamic performance, a more powerful and effective. Acceleration 0-100 km to 19 seconds for 15 seconds, a time of hydrogen continues to extend the charging mileage 300 km from 230 km above the maximum speed of 120 km to 150 km. In addition, it is a higher degree of the integration, vehicle stability, reliability has also been enhanced.

Similarly, the fourth generation of power systems equipped with Shanghai Volkswagen Passat Passat, Chery Oriental Son has a top speed of up to 150 km, 0-100km acceleration time of less than 15 seconds, filling a gas Hydrogen can travel 300 km, the performance does not differ much with the international advanced level.

In addition, Dongfeng Automobile also entered the field of fuel battery vehicles to hydrogen. In August 2004, Dongfeng Motor and Wuhan University of Technology, in collaboration with the Elysee as a platform, a car developed hydrogen fuel D5318 HD438 battery – “Chutian One.” It is equipped with a hydrogen fuel battery of 25 kW as the engine, the maximum speed of 103 kilometers, but a shorter distance endurance.

Hydrogen bus fuel battery research and development in early 2002, the Tsinghua University as a unit of lead, with Dongfeng Motor Corporation, Beijing Bus Plant and five other units of the whole group, the bear National “Tenth-Five” 863 Year Plan for Fuel Battery Bus Project City search. Tsinghua University has also made clear to China Beijing Tong Technology Development Co., Ltd as an industry based carrier.

Currently, the most recent Taiwan bus fuel battery with hydrogen to reach a maximum speed of 90 km / h, a maximum mileage of hydrogenation of 300 km, engine power 100 kW . This is the advanced international level, there is a significant gap. IBM ThinkPad T40 battery  IBM ThinkPad T41 battery

November 15, 2007, marketing projects in China bus demonstration fuel battery to begin the second phase of bidding to provide Shanghai 3 ~ 6 working condition for the Shanghai Urban Transit bus fuel battery one of two pilot years.

Relevant experts suggest that China has developed a bus fuel battery, the Chinese government has invested a lot of money. Abroad, the high cost of bus fuel battery, to promote the formulation of China policy and the establishment of standards and regulations, the proposed fuel-battery cars in China may also be added in the ranks of demonstration runs.

In the engine control technology vehicles, the level of leading domestic and international level despite the differences, but this is not the most important development of hydrogen fuel batteries difficult. The key issue lies in the hydrogen and the power of A1022 A1078 battery life.

Wang Binggang said that the current fuel battery hydrogen internal stability of life is still about 2000 hours, well below the hour international Baqian Qi. Power battery life less than two years, while Japan is 3 to 5 the most advanced years.

It should be noted that multinational companies were involved in vehicle fuel-battery home.

The second approach – in collaboration with the multinational

In 2004, GM and SAIC signed a clean-energy vehicles strategic cooperation framework agreement, both parties reach an agreement: access “Hydrogen III battery vehicle hydrogen fuel from the first quarter of 2005 in China, one of two pilot operation years. General Motors in 2002 introduced “Hydrogen III” as a basis, the Pan Asia Technical Automotive Center in North America and General Motors German engineering under the direction of a series of integration and the Pan Asia Technical Automotive Center will responsible for the vehicle’s future operation and maintenance.

In 2001, SAIC Group and General Motors joint venture between China’s Pan Asia Technical Automotive Center in Shanghai, with respect to the Buick GL8 presented a BATBL50L6 LCBTP03003 prototype vehicle fuel battery called Phoenix.

China 2005 marketing bus fuel battery demonstration project bidding, General Motors, SAIC has supported to participate in the project submission, and provide fuel when the most advanced systems-GM training batteries. Currently, Shanghai Volkswagen Passat also produces battery vehicles to hydrogen fuel, but will participate in transport services during the Beijing Olympics.

Former Vice President of SAIC Wang Ta-General said, because a number of colleges and universities support the program 863, and may not be appropriate to give the latest global technologies to SAIC fuel vehicle hydrogen fuel battery research and development does not rely entirely on 863 plans, in cooperation with multinational corporations are too.

SAIC person who fails to disclose in research and development activities which form of cooperation. However, journalists have learned that domestic firms in the electronic engine control, control technologies for vehicles, both traditional energy sources, or developing new energy vehicles, are cooperation with multinational companies, as Bosch GmbH of Germany to develop technologies for electronic engine control.

The reporter noticed a cooperation agreement with SAIC GM also include “Development of vehicle fuel battery hydrogen from China to contribute to standards and rules,” such provisions. Therefore, do not exclude the use of SAIC-GM vehicle fuel PA3591U-1BRS  PA3191U-4BRS battery with hydrogen on the Chinese standard setting influence.

When power, coal, oil and not other sources of renewable energy most often in cases of urgency, energy is increasingly a bottleneck limiting the international socio – economic development, a growing number of countries have begun to develop solar energy resources, to seek a new driving force for economic development. The solar battery is a very good application. At present commercial production of solar batteries are primarily inorganic material (such as silicon, high purity) as raw materials made from inorganic materials such expensive solar IBM ThinkPad X60 battery  FRU 92P1141 batteries, and thus a number of other producers of electricity compared to lack of competitiveness (such as coal-fired plants). The future direction of the mainstream of solar batteries to stress is lighter, more flexible and, above all, cheaper. And a new type of solar battery exactly in line with the thrust of this development, which is an organic solar batteries. Because the battery will no longer be inorganic materials as raw material, but instead of using organic materials. Made of plastic and other organic materials, new type of solar battery will have a more flexible and inexpensive features lightweight, allowing them to be widely used in many new areas.

Organic active layer METHOD OF GENERATING

Plastic solar batteries using organic semiconductors, which will greatly improve the energy conversion efficiency of solar batteries, but also reduces manufacturing costs. The current battery of organic matter to overcome the major problem is to increase energy efficiency because it uses material absorption. This material has the charge separation and transport functions of loads in a controlled form “sent to” the active layer of solar batteries. Dell Latitude D410 battery  Dell Latitude D500 battery

And silicon is similar to organic photovoltaic (OPV) battery in the active layer as the electron donor and receiving electronic body composition. And then no longer be the active layer anode (indium oxide and tin) and cathode (Al) surrounded by the medium.

The operating principle of this battery is not complicated. When light radiation you will stimulate electronic materials for them from the original track (the highest occupied molecular orbital) in the excited state, leaving a positive charge. This has been motivated to be movement in the electronic layer active, and enter the body of the electronic receipt of the molecular orbital alternative minimum. Finally, moving to the cathode through the electronic circuit outside for reinstatement, forming a gentle current.

Cleverly constructed to solve the problem of efficiency

In fact, the use of solar batteries based on organic materials can improve the efficiency of the key is that they have the characteristics of a low permittivity, the flow of electrons in which the distance F2024A F2024B batteries inorganic solar is relatively short. However, in its manufacturing process have also encountered a problem. To make an electron donor and the receiver’s body more efficient transfer of electrons between organic solar batteries the thickness of the two should be about 10 nm. But more often to ensure maximum absorption of light, the average thickness of organic materials require greater than 100 nm.

However, this apparently contradictory behavior can optimize the active layer structure to be solved. During the manufacturing process can be an electron donor and receiver dispersion and arranged to expand its size, the formation of an electron donor and the receiver’s body structure of the network interspersed with each other, so that not only ensures the absorption of light but also ensure its thickness does not affect the efficiency of electron transfer.

A perspective of market wide

When the majority of the new solar battery is still experimental, energy efficiency has been consistently exaggerated the time, materials, organic solar batteries can reduce the potential cost of electricity has been a concrete way for people to discover and begin to be used, because these organic materials, semiconductors can be mass produced and flexibly applied to various fields. Today, around the world, scientists and engineers are trying to develop this technology to reach previous business goals.

Recently, the Australian Commonwealth Scientific and Industrial Research Organization scientists a printing of banknotes successfully conducted a test print. Experience with the highest rates of press operation, can reach 200 meters per minute printing. Assumed efficiency of 10%, then the press can be of 5 months of continuous use, electricity generated by solar batteries is equivalent to one million of power per kilowatt.

Despite its many advantages, low cost energy production is also very potential market and organic solar batteries still needs more investment and further development in order to enter the market for consumers to use, especially its stability problems must still be resolved. However, this has led to the bright future of the A1012 A1060 battery lead the people towards a more environmentally friendly, energy development more sustainable.

Like talking on the cordless handset and wait longer and longer, but also support other types of complex wireless applications, integrated power is becoming a significant demand for these products. This article will deal with the battery, battery systems and energy conversion. We are the first topic for discussion is the heart of the system: the battery. The content of the discussion include the type of battery, VGP-BPS9/S VGP-BPS9/B battery charge and discharge, as well as system maintenance, we will consider energy needs, safety considerations, costs, unit cell (cellular) number of impacts environmental, life cycle, the unit cell fixed amount. Mesh, battery and battery the battery is a chemical reaction is an inherent tension, the battery voltage is the nature of a chemical reaction, its structure or the size and battery size. If a component can produce such an inherent tension is called a “cell unit” (cell). A battery “(battery) May contain many units of batteries can be series, parallel or mixed with, and all placed in the same case in the file. In a shell “stack” (attached) in the battery or batteries in multiple units, and these units has its own battery or the battery case, then the shell pile is called “battery (pack). Applications can also use multiple battery packs, perhaps because it required power exceeds the supply capacity of a battery, perhaps to allow a battery, the other battery is charging or maintenance. Such applications may have circuits of battery management requirements of some other order in the charge cycle at different times or under different conditions of installation and removal can be performed sequentially on each battery. Cell Structure, nomenclature unit cell there are two reaction surfaces, their chemical composition is not the same, and by a chemical reaction can not afford to separate the conductive layer is not fixed separated in the reaction between the surface will be filled with electrochemical reaction of a good material, known under the name of the electrolyte in the battery the more commercial, the electrolyte is a liquid or a gum, but in some rare cells May be gas or solid. The surface reaction, there are contacts of the circuit (tabs), in which a high potential for contact materials are in contact, equipment and low potential for negative contact. Inside the the battery case there are two particular areas to the other for non-drivers, mainly the battery positive and negative of these positive will be connected to the device via a line inside the PA3399U-1BRS PA3399U-2BAS battery positive contact, the electrode be negatively related to negative contact. Since the vast majority of cells are cylindrical, so that vendors will be covered with a layer of anode material of the separation layer, then covered with a layer of material of anode, the final when they are rolled into cylindrical cells. On the other hand, if we can reduce these layered materials covered, you can make a space more battery saving square. Lead batteries of acid on the use of the square of the hull, the battery will be added in the electrolyte, and then the positive and negative electrical panels panels rotate film is fixed, and immersed in the electrolyte. What the battery? The battery using chemicals or ion exchange reaction, the energy stored in the potential field that result. For disposable batteries (or battery) that want to use the circuit operation restoration of these reactions is a thing possible or practical, but for rechargeable batteries (also known as secondary batteries) and the words, if we applied a voltage, which is more important than the battery voltage, you can restore these responses, while the energy stored in the stack, rather than removing power from the battery. Battery management is running a series of chemical reactions. Battery Why do we need management? The so-called “secondary chemical reaction” means a place in the pile of the chemical reaction between components, that is, store and release energy and thus a reaction other than a chemical reaction. secondary reaction will not be released as heat further, but with time and the life cycle (time of loading and unloading) increase, but also produce some solid, liquid or gaseous, in particular the reaction in solid impurities in the cell surface on the crystal and the burden of coverage can be used to store a page of “reaction” (reaction sites). The heat of evaporation of liquid or gaseous electrolyte lighter components, if the rate of gas production is higher than components of the A1060 M8403 battery can absorb, it will generate the internal pressure of a sealed battery, sealed battery without cause “gas leak” phenomenon, and change the combination of chemical ingredients. If we are already at full potential in a battery continue to exercise power, then the rate of secondary reactions will accelerate significantly, the battery is so-called “on-load (overload), it not only reduces the capacity of the battery storage loads, but also shorten the life cycle of the battery; In addition to the chemistry of the battery some, excessive discharge May cause the same effect. To release the pressure inside the battery may be sealed by these gases at high pressure is off, it may cause temporary or permanent damage. The battery has a “self-discharge rate (rate of self-discharge), which refers to the current supply of external loads n ‘ is not the case, the battery of its own “escape” velocity of electricity storage. When the battery is finished loading, we still need to perform maintenance or “floating” (float) charge, and the percentage rate shall be equal to the battery-discharge rate for the battery remained at full power state. Batteries are often used together in series or in parallel. If the adoption of these works, so that a slight difference between these batteries, it is possible for the chemistry of the battery some have a huge impact. Therefore, the battery manufacturers and OEMs require batteries must have the same chemical manufacturers, the time to plant, and even the number of production lot. And even a little chemistry of the battery or the need to keep all batteries. Of all the commercial batteries, manufacturers will be in the unit cell to release pressure within the structures of security to on-load situation is extremely serious, in a gas emission control. Some cells also contain components, as well as components fuse-temperature protection, which are the most common lithium-ion batteries. Choose rechargeable batteries, the chemical mechanism that will be used to select for specific battery chemistry, we must let the battery chemistry and applications of characteristics that complement each other in business applications today, it are five kinds of commonly used battery chemistry.

Traditionally, consumer products, appliances are mainly nickel-cadmium batteries, rechargeable batteries, because the nickel-cadmium batteries are a mature product, and we understand the chemical reactions of nickel-cadmium batteries. On the other hand, metals cadmium, their administration has become increasingly stringent in some areas, it must also make recycling compulsory associated with nickel-cadmium batteries is a mature product, and thus the capacity and life cycle not too much room for improvement. Compared to nickel-cadmium batteries, in terms of unit weight or unit volume density of energy storage, batteries nickel hydride provide a significant performance improvement of lithium-ion batteries in turn , went further, because its density storage of electrical energy that more than double nickel-cadmium batteries. Although nickel-metal hydride or lithium-ion chemical mechanism has its merits, but the drawback is that the circuit very sensitive to them, the lithium-ion mechanism, in particular clear that c ‘ is not only because the battery is damaged by mismanagement and electrolyte May ignite if the battery management is very important. Manufacturers will normally be an internal lithium-ion battery with a number of mechanisms for protection against defects to voltage / current is too large or the temperature is too high, and when the battery charge and / or circuit feeder between the cup In addition, most vendors will be inside the battery installed another series of special tours can be restored to provide protection. However, nickel-metal hydride or lithium-ion PP2182L HSTNN-LB31 battery power supply capacity is still smaller than nickel-cadmium batteries for more power, but can not use external power of the vast majority products, nickel-cadmium batteries is always the best choice. Alkaline batteries with rechargeable batteries as well as the shape of the main purpose is to replace these disposable batteries, although the price of an alkaline battery is about twice as much, but the battery life is concerned, the overall cost of the latter is much weaker. For the application of low current applications, they are not only the chemical mechanisms charge the most expensive, but it also has the lowest self-discharge rate. Life of rechargeable alkaline batteries in the shortest cycle of disadvantage is that if all cycles of charging and discharging, the battery is fully charged, then the type of battery can be used about 25 times.
