Japan and South Korea are the key technical leader for battery electric vehicles

Electric car craze in full swing, but also because it appears that the Detroit auto show is not the end of the cool! Electric car one of the rechargeable batteries used in electric vehicles is the key to the development of technology. To this end, some motor vehicle dealers in Japan have the battery technology with the traditional strong vendor or co-operation or participation, such as Toyota and Matsushita old partner, Nissan and NEC to develop strategies such as auto-rechargeable batteries or rechargeable batteries. Then, at the world's major car manufacturers have to develop electric cars as part of the company's current strategy for the future development of the global automotive battery technology and how this pattern? How it will affect the future of the global car industry map changes? One of the most concern to us BYD-iron battery technology in a kind of position do? Let us take a look at the electric vehicle industry, senior analyst at the HUNTET HSU-depth analysis and introduction. Automotive Electronics is the trend of broad prospects for electric cars Universal Group of the United States in 2008 by a hundred years at plants Renqing moment, the formal launch of mass production version of Chevrolet Volt to open a new era of electric vehicles. With consumers growing awareness of environmental protection, the same general group of the German brand Opel also announced at the Geneva Motor Show in 2009, launched "Ampera" the new electric cars. Used four five-set Ampera, Chevrolet Volt and in fact there is a considerable degree of similarity: In addition to the headlights swept the long and narrow lines of the same things, Ampera narrow use of the water tank shields, while the lower edge of the headlights also add similar Flextreme concept car with the factory intake gate design, a dynamic avant-garde design. Aspects of power, Ampera with common power system Voltec Group, the owner may, by a 230V AC power for charging Li-ion sony laptop battery module in the case of full electricity, Ampera available distance range of 60 kilometers; the way those who are driving farther, Ampera by small internal combustion engine with the engine, but also continued to produce electricity in order to provide more long-distance capacity of endurance.
As the capital market on the first group of electric vehicle industry one of the researchers, I have the opportunity to use the last of the technical bottlenecks in the electric car to do a preliminary analysis. The introduction of electric vehicles will be my key to the core components: auto-rechargeable (secondary) sony pcga-bp1n ! Vehicle because of the rapid development of electronic applications, automobiles are no longer traditional mechanical products, but has all the modern technology in an intelligent, integrated optoelectronics, semiconductors, electronics, communications technology, integrated platform. 2004, each new electronic products in 1518 U.S. dollars spent, but also someone with the mechanical and electrical integration estimates the continuous advancement of technology, the future costs of electronic products is expected to reach 40% of the cost of vehicles. Corresponds to a high degree of electronic vehicle trends, the automobile industry to promote 42V or 42V/14V power system has also gradually speed up. Automotive electronic systems demand for electricity between now and year 2030 will maintain a 5 ~ 8% of the rate of growth, at transitional phase 42V/14V power system from generation to generation is expected to become the new standard vehicle power system. At present, foreign advanced car electronics required more than 2000 of the wiring harness, various control devices to connect more than 4000 points, the total length of wiring harness more than 4000 meters,sony pcga-bp2nx, the weight of more than 40 kilograms. The future after the switch to 42V power system, the existing cross-sectional area of wire from the mainstream of 0.5 ~ 1.5mm reduced to 0.35mm. Voltage improve vehicle performance benefits at: (1) the same power, the wire current to flow through small, cost of each and every wire ohmic loss, fuel consumption could be reduced by 10 ~ 20%; (2) saved by the wire Spaces can be added to the new electronic system; (3) the use of aluminum instead of copper wire, to a more narrow size; (4) in line with the needs of the development of hybrid vehicles. With the vehicles 42V power system time on the energy storage media / battery demand will further increase. Since 1800 Alessandro Volta invented the world's first battery in 1859 Gaston Plante invented the lead-acid rechargeable battery, the engineers never stopped looking for ways to better the efforts of energy storage. Chemical batteries or rechargeable batteries based on the characteristics, are divided into "a cell" and "secondary battery" two broad categories. Including a battery on the market common alkaline batteries, mercury batteries, and manganese dry batteries, silver oxide sony pcga-bp2r, lithium batteries, such as air batteries, rechargeable batteries for portable electronic products is currently the bulk of applications, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries, lithium polymer batteries and super capacitors. Lithium-ion batteries in 1990 to come out and finish the business in 1991, and the 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 has security concerns there.
To explore future trends in automotive batteries, starting from two directions: a function of charge and discharge rechargeable battery power and the provision of the electrochemical cell, which the mainstream for the past lead-acid batteries, but because of hybrid-type of secondary sony pcga-bp2s significantly improve the performance requirements. Ni-MH (nickel-metal hydride batteries) because of excellent value for money and more security (as opposed to lithium-ion batteries) and has high energy density, power density, rapid charge-discharge, long cycle life and no memory effect, no pollution, can be maintenance-free, the use of fully characterized, is known as "green battery." Ni-MH batteries are the energy density of nickel-cadmium battery 1.5 to 2 times charge-discharge without memory effect, low temperature characteristics of good, overall performance is superior to nickel-cadmium batteries, nickel-cadmium batteries and no batteries to deal with the problem. At present, the majority of the market are hybrid-type Ni-MH battery selection as a storage medium for energy recovery. The future if the cost of lithium batteries and vehicle safety performance in line with the requirements of nickel-hydrogen batteries to gradually replace the trend of a few can be identified.
Much hope that the industry can not wait to be able to study the dismantling BYD F3DM At present, the global lithium-ion / Li-polymer sony pcga-bp2t market vendors concentrated in the Asian region, Japan, Korea, Chinese mainland and China Taiwan manufacturers sub-regional food market pie, one of grasp the technological superiority of Japanese firms to occupy 80-90% of the market share , standing hegemony. Japanese firms to develop lithium-ion / Li-polymer of the oldest, technology and the stability of quality at the industry leading technology from Japan to copy the South Korean manufacturers are behind because there is Samsung, LG and other companies to support, some good score. Lithium-ion battery cathode mainly by internal, cathode, electrolyte and membrane composition, due to positive and negative electrode and electrolyte materials and called different names in different. Currently on the market for lithium-ion battery cathode material is lithium cobalt oxide (LiCoO2), the other a small number have used lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2) cathode materials for lithium-ion batteries, the two have been at hand-held electronic products in a very universal. So far, not been able to iron lithium battery of large-scale commercial Lithium-iron sony pcga-bp2v has a behind the back of the complex patent disputes Is apart from lithium-ion batteries, there is no other battery technology of electric vehicles can meet the needs of the market? The answer to this question is also negative, including the depot into a large number of Honda fuel cell R & D resources, as well as BMW have experimented with the "super capacitor" technology are viable options, the latter with the FIA is to vigorously promote the F1 track in the kinetic energy recovery system (Kinetic Energy Recovery Systems, referred to as KERS) is closely related to the future, I also detailed description of the author.
