Three new energy vehicle power lithium battery bottlenecks need to be solved

The future of new energy vehicles gradually replace conventional gasoline automobile industry has become the consensus, as a central element of the battery is more optimism about the companies and investors. Dell Inspiron E1405 Screen Dell Inspiron E1505 Screen

Insiders said that the new energy vehicles demanding on the battery must have a high specific energy, high specific power, fast charging and deep discharge efficiency, and requires the cost as low as possible, the duration of life as long as possible.

New Energy Chamber of Commerce, National Federation of the implementation of the Secretary-General Wang Hai-Yue told reporters that traditional batteries Lead-acid, nickel cadmium batteries and battery technology it nickel-hydrogen itself is relatively mature, but they are used in car batteries as the power, then there is a big problem. Currently, car manufacturers increasingly choose, such as lithium new energy vehicles. Because the lithium-ion high power (a nickel-cadmium batteries, nickel-hydrogen three times), high energy (up 165WH/kg, nickel-hydrogen battery is 3 times), small size, light weight, long life, the rate of self-discharge, no memory effect, no pollution and so on.

However, Harbin Institute of Technology, Professor Guo-Xin Hu believes that although the power of lithium as new energy vehicles is a better choice, but because of its outstanding achievements in basic technologies The development of bottlenecks lithium battery are met.

Xin-Guo Hu stressed that the lithium batteries for power and price, safety and vehicle battery issues management system. Key Features:

Production costs are high. Currently used in the cost of electric vehicles battery power account for half the cost of the vehicle, but a car battery cost-effective power can achieve the performance and cost of industrial needs.

Security must be improved. As the lithium-ion battery with an energy density, high temperature characteristics of the safety of users of batteries have very high demands. Dell Inspiron Mini 12 Screen Dell Inspiron Mini 9 Screen

the power of the vehicle’s battery management system must be improved. car battery must be several batteries in series to increase voltage, but it is difficult to achieve because the battery charge and discharge completely uniform, both batteries in series within a single battery charge and discharge is an imbalance, causing the battery of the rapid deterioration of the battery to run the group also will not work or even abandoned, a large impact on battery life and reliability. toshiba pa3399u-1brs

It is understood that the countries in research and development of the lithium battery has invested considerable financial and material resources. 863 plans to establish a major specialized electric vehicles, the Chinese Academy of Sciences Institute of Physics, Beijing Nonferrous Metal Research Institute, China Electronics Technology Group Corporation 18th Research Institute and other units involved in the project were the development of EV and HEV battery types, including some units have adopted a security system of the cathode active material of manganese. “Eleventh Five-Year, $ 863 electric vehicles in major new projects HEV, PHEV external plug-in hybrid vehicles, FCV fuel cell vehicle materials using lithium-ion battery and supports research and development.

Experts suggest that the power of the lithium-ion batteries for proper application, the firms in upstream and downstream must cooperate on drums as the heart, including the materials, systems management, forming an industry group that will beneficial to technical progress and reduced system cost. toshiba pa3384u-1brs toshiba pa3395u-1brs
