"From a few car running more than a year of testing results, chunlan found no attenuation of these lithium battery capacity, quality is reliable." Hunan zhuzhou electric vehicle demonstration operation base engineer said.

In addition to zhuzhou, now in wuhan, dalian, Beijing and so on more than a center city, the chunlan ni-mh and lithium ion battery of the hybrid and pure electric large passenger cars, commercial operation is running or demonstration. Many rides, researchers said assembly chunlan electric supply system of electric bus, good performance, low noise, low failure rate, the operation is very stable.

Has officially by state general administration of quality supervision comprehensive evaluation, make examination organization issued by the "customs declaration token" chunlan power lithium ion battery, now get more and more the favour of electric vehicle manufacturers.

According to introducing, power lithium ion battery is a kind of light weight, high than energy and power, small volume, long cycle life, no memory, low self - discharge rate, temperature range is wide, and many other advantages of green battery, is the first key parts of new energy vehicles. In recent years, countries have invested huge funds for new impetus of including power lithium ion battery, the battery research and manufacturing.

To promote the sustainable development of new energy industry and improve the product series, seizes the international high-end market power battery, as early as a few years ago, chunlan and relying on abundant power ni-mh battery research and development production experience and deep research for lithium battery. Over thousands of times of charge, over discharge, short circuit, extrusion, and many other comprehensive experiment, chunlan fully mastered not only improve power lithium ion battery with high power, low temperature, cycle life and safety of main performance such as key technology, and further improve the dynamic performance of the lithium ion battery, which reached the leading domestic level. According to authoritative testing institutions for more than a year of testing, chunlan power lithium ion battery can be in 25 degrees below zero Celsius in the bad environment, can meet more than 2000 times charge and discharge, life more than eight years, than ordinary power lithium battery service life of the high three times.

As "jiangsu province power battery industry technology innovation strategy alliance led units, as well as the largest of the new energy automotive power battery and supplier management system, chunlan 58 in the field of power battery has received national patents, including 28 for a patent for invention, not only formed a relatively complete product series, and it has the key materials, battery formula, industrialization and so on the core technology and independent intellectual property rights.
