The Study on Charge-discharge Characteristics and Application of Li-ion Battery for Vehicle

To view the working performance of li-ion battery used for electric vehicles,the of charge-discharge experiments of Li-ion batteries were corried out. The performance curves of the battery were derived from the experiment results,including cell,pack and road test.The conclusion presents that the SOC value can be evaluated by the SOCV value ,and the target value of the SOC is suggested. The results show furthermore that the battery is of a good environmental adaptation and high current charge-discharge capability.It is also discoveried that the driving range should be limited.
