<title> Electric car craze in the ascendant, and it seems that not since the end of the Detroit auto show has been cool! One electric car rechargeable batteries used in electric vehicles is the development of key technologies. For this reason, some Japanese auto companies have a strong traditional battery technology vendor or cooperation or equity, for example, with the old partner Panasonic Toyota, Nissan and NEC to develop such a strategic vehicle battery or a rechargeable battery, said. So, the world's major automobile manufacturers regard the development of electric cars as the company's future development strategy of the present, the global pattern of apple a1189 laptop battery technology is what happened? How will it affect the future of the global automotive industry, the territory of changes? In which we are most concerned about BYD-iron battery technology also is in a kind of location? Let us take a look at electric vehicles, industry analysts, senior HUNTETHSU of subtlety in-depth analysis and presentation.
E-car trend is promising electric car
U.S. General Motors Group in 2008 through the time of celebration a century plant, officially launched the production version of the Chevrolet Volt electric car to open a new era. With the growing environmental awareness among consumers, are both common Group also announced that the German brand Opel in the 2009 Geneva Motor Show, launch the "Ampera" the new electric cars. Set with five 4 Ampera, in fact with the Chevrolet Volt a considerable degree of similarity: In addition to narrow lines, swept headlamps identical things, Ampera narrow range of water tanks using shields, while also joined the lower edge of headlight similar to the Flextreme concept car with the factory intake grid design, presenting dynamic avant-garde design. Power connection, Ampera equipped with GM's Voltec power system, the owner may, by a 230V AC power to recharge the lithium battery module case of full power, Ampera can provide the traveling range of 60 km distance; who intends to drive further along the path, Ampera by a small internal combustion engine equipped with, but also continued to produce electricity, to provide more long distance endurance.
As the capital markets concerned about the electric car industry, the first group of researchers, one that I have the opportunity to use the last technology for electric cars have done a preliminary analysis of the bottleneck. This time I will introduce electric cars key core components: vehicle rechargeable (secondary) batteries! As the vehicle for the rapid development of electronic applications, cars are no longer the traditional mechanical products, but has all the modern technology in an intelligent, integrated optoelectronics, semiconductors, electronics, communications, technology, integrated platform. In 2004 every new car in the electronic products, expenditures 1518 U.S. dollars, but it was estimated as the mechanical and electrical integration of technology continues to progress, the cost of the future of electronic products is expected to reach 40% of the cost of vehicles.

Corresponds to a high degree of electronic vehicle trends, the automotive industry to promote 42V or 42V/14V power system to speed up the intensity gradually. Automotive electronic systems demand for electricity from now to 2030, will maintain an annual rate of 5 to 8% growth in the transition phase 42V/14V power system is expected to become the new generation of vehicle electrical system standards. Advanced car electronics products in foreign countries, the needs of more than 2000 wiring harness, various control devices connection points over 4000, the total length of more than 4000 meters wiring harness, weight is greater than 40 kg. After the next switch to 42V power system, the existing mainstream wire cross-sectional area reduced to 0.5 ~ 1.5mm by 0.35mm. To improve the benefits of the car voltage is reflected in: (1) the same power, the current flowing through wire is smaller, reducing the loss of each wire ohms, thus reducing fuel consumption could be 10 ~ 20%; (2) wire to save out of Space can be added a new electronic system functions; (3) using aluminum instead of copper wire, size can be further reduced; (4) comply with the needs of the development of hybrid vehicles. As the vehicles 42V power system time, electric energy storage media / battery demand will also be further enhanced.
Electric vehicle technology, Japan and South Korea Win in Chernical temporarily lead the world
In 2006 the global battery market (not included low-zinc-manganese dry battery) to 54 billion U.S. dollars in the next four years will be 6.9% per year compound annual growth rate increased steadily.
Over the past has been the use of the sony vgp-bps3 laptop battery flashlight, radio, cars and motorcycles start the power to today's 40-50 kinds of uses, can be said that an essential energy source for human society. Demand for car batteries battery market accounted for more than one-third of the total demand (34.2%, as shown in Figure 1), even from the current annual growth rate of 2.1% (in 2007) rose to 9.2% (2010). Be regarded as key components of next-generation hybrid vehicles, lithium-ion battery (growth of 81%) and super capacitor (growth of 120%) is expected in the next five years to grow.
Since 1800 AlessandroVolta invented the world's first battery, invented in 1859 GastonPlante rechargeable lead-acid batteries, the engineers have not stopped efforts to find a better storage methods. Chemical batteries, rechargeable or not based on the characteristics of the battery is further divided into "one cell" and "secondary battery" two broad categories. A common market, alkaline batteries, including batteries, mercury batteries, and manganese batteries, silver oxide batteries, lithium batteries and air batteries, rechargeable batteries, compared with the current application of large portable electronic products, including lead-acid batteries, nickel cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries, lithium polymer batteries and super capacitors. Advent of lithium-ion battery in 1990 and was completed in 1991 to commercialize use of gel polymer electrolyte for polymer electrolyte membrane and the lithium-ion batteries were introduced in 1995 and commercialized in 1999. But lithium-ion battery package that there is always the safety concerns.

To explore future trends in automotive batteries, starting from two directions: have a charge and discharge capabilities powered by rechargeable batteries and electrochemical cells, the former mainstream as the lead-acid batteries in the past, but because of hybrid-type of secondary battery a substantial increase in performance requirements. Ni-MH (nickel-metal hydride batteries) as compared with excellent cost performance and security (as opposed to lithium-ion battery) but also has a high energy density, power density, fast charge and discharge, long life cycle, and non-memory effect, no pollution, can be maintenance-free, use the full characteristics, known as the "green batteries." Ni-MH battery energy density of nickel-cadmium battery 1.5 to 2 times, no memory effect when charging and discharging, low-temperature characteristics of a good, overall performance is better than nickel-cadmium batteries, nickel-cadmium battery waste nor the battery disposal problem. The majority of hybrid vehicles currently available are select NiMH batteries as a storage medium for energy recovery. If the future cost and safety performance lithium batteries meet the vehicle requirements, to gradually replace the trend of several nickel-metal hydride batteries can be identified.
Many industry people who can not wait to be able to study the dismantling BYDF3DM
The current global lithium-ion / Li-polymer battery market vendors concentrated in the Asian region, Japan, Korea, Chinese mainland and China Taiwan-based players eating into the market pie, which grasp the technological superiority of the Japanese companies account for 80-90% of the market share of , supremacy firms. The Japanese manufacturers to develop lithium-ion / Li-polymer have the longest history, technology and quality of both the stability of the industry leading, technology copied from the Japanese manufacturers in South Korea because of behind Samsung, LG and other makers support, there are good results. Mainly by the internal lithium-ion battery cathode, anode, electrolyte and membrane composition, due to positive and negative electrode and electrolyte materials, which goes by different names in different. Currently on the market for lithium-ion battery cathode material is mainly lithium cobalt oxide (LiCoO2), plus a small number of used lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2) as cathode materials for lithium-ion battery, these two have been in the handheld electronic products, very popular.
So far, not been able to iron lithium battery of large-scale commercial
Lithium-ion battery cathode materials prices and raw material prices of metals Quotes consistent, of which cobalt (Co) is most scarce, nickel (Ni), manganese (Mn) is less expensive, but prices have sharply constrained electric cars to reduce costs in order to achieve universal possibilities.
At present the most promising are based on lithium iron phosphate (LiFePO4) battery cathode material for lithium-ion batteries, because iron ore prices are much lower than other metals. Lithium iron phosphate battery life is 4-5 times of ordinary lithium batteries, there are 8-10 times higher than the lithium batteries of high discharge power (which can produce large instantaneous current), together with the same energy density of lithium batteries to reduce the overall weight than the 30-50% and other features, it is considered the most suitable require large torque electric vehicle using secondary battery technology. This is reportedly the world's stocks of God Warren Buffett (WarrenBuffett) spotted BYD shares depot and an important reason why, but the technical team on the BYD owned by the "iron battery" technology content, is still in the industry and the invest in a huge circle of the controversy caused by its mystery I am afraid to wait until the F3DM only when consumers know little about mass production in the future I will be behind this special article written for the complex patent disputes instructions.
Behind the iron lithium battery has a behind the complex patent disputes
Is In addition to dell inspiron 510m laptop battery, there is no other electric vehicle battery technology to meet the needs of the market? The answer to this question is also negative, including a large number of R & D resources devoted depot Honda fuel cell areas, and BMW have experimented with a "super capacitor" technology are viable options, the latter with the FIA is being strongly promoted within the F1 track momentum recovery system (KineticEnergyRecoverySystems, called KERS) are closely related.
