Current hybrid vehicles use nickel-metal hydride battery technology major, but some hp pavilion dv9000 battery, hp pavilion dv2 battery technical performance such as energy density, charge and discharge speed is close to theoretical limits. The lithium battery with energy density, high-capacity, no memory, etc, get the car makers and battery manufacturers unanimously approved, is currently the focus of national research and development of lithium-ion battery.
According to different cathode materials, lithium batteries are mainly lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate ternary material and the four. Lithium iron phosphate which is the best hybrid vehicle with lithium cathode material. At present, enterprises in China car model launched in pure electric vehicles, power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate.
China’s “Auto Industry Promotion Plan” proposed a new energy vehicles in 2012 accounted for 5% of total production of vehicles, about 500,000. Industry experts predict that by 2020, China 10% to 20% of passenger car sales will come from pure electric cars, plug-in hybrid and other new energy vehicles.
Renault – Nissan alliance CEO Carlos Ghosn predicted that the next 10 years is estimated conservatively that 10% of consumers would buy dell inspiron e1505 battery, dell vostro 1310 battery electric vehicles. It appears that the forecast high.
According to the electric cars around the bus taxi planning, I guess the next 3 years 200 000 of these electric cars and hybrid road. Shenzhen has 30 vehicles on the road, Chengdu plan 3 years 1000 bus is on the road, the market size is around this level. Other OEMs a show, celebrities take the lead in environmental protection, and other large companies will have 300,000 bus pilot road electric vehicles. A total of approximately 500,000, 3 years the market demand.
“The future development of electric vehicles in China is that China’s auto industry and the world automobile industry closer to the most convenient way. Companies doing fuel vehicles, we must also make preparations for future market and competition. Can not wait until fuel vehicle market decline, and wait until the electric car market flourished do fully prepared to seize on opportunities for business growth is very important. “BYD BYD Wang are treated this way or that China’s auto development of electric vehicles significance.
Learn from China’s IC 15-year history, did not achieve the desired application of the main reasons is not a technical problem. Actions such as early development of the BB machine with IC, but the application to promote ineffective ausu a32-f3 battery, asus a33-f3 battery, missed market opportunities. Later, the MP3 decoder chip system-level thinking, to facilitate the application was successful.
I think the electric vehicle charging station is a key factor. PetroChina and Sinopec are both even behind the charging stations, and investment in the lithium battery industry, I hope they do practical things. I saw in Shenzhen, BYD, Kwai Chung, charging station, told Shanghai Cao Xi Electric Vehicle Charging Station by acceptance. After all, is too little!
Li-ion battery development issues: Despite China’s lithium production ranks third in the world, but the core material to be imported batteries. Xinhua said the letter and other related research institutions, China’s relatively backward power battery production equipment, many companies will focus on the material, ignoring the improvement of manufacturing equipment. Power battery in high-volume production, it should be advanced automation of the first place. In addition, most of the enterprises in China battery independent research and development, its limited funds, can only solve the basic problem hp pavilion dm3 battery, hp pavilion dv6 battery technology is difficult to further advance. Lack of adequate communication between enterprises, both would like to know of others rather than on their own experience, there is widespread duplication of low-level phenomena.
I add two points, the opportunity for electronics manufacturers is the lithium battery circuit protection, intelligent charge management and explosion-proof technology. Industry technical standards for government action must have the strength of TD, can not engage in the standard group. EVD standard DVD, so a group of imitation did not happen, a waste of time and resources.
Li-ion battery needs to be a real thing than 5 to Hom: materials, equipment and technology, universal charging station, the industry standard and intelligent charge management.
