转移式电池均衡技术在电动汽车中的应用研究

Research on Application of Transfer Battery Balance Technology in Electric Vehicle

电动汽车的电池在真正投入使用时,由于环境影响,可能会出现电压不稳的问题。而且这种不均衡的供电模式可能会逐渐加重,造成电池内部结构损坏,使电池组无法供电,威胁到电动汽车的行驶和安全。研究者发现,使用转移式电池均衡技术能够从电池外部解决电池组内部电压问题所造成的电池组稳定性缺乏、续航时间短、使用寿命短等问题。文章阐述了电动汽车当前所处的发展阶段以及所使用的电池模式,并分析了转移式电池均衡技术在电动汽车中的应用。

When the battery of electric vehicle is really put into use, the problem of voltage instability may arise because of the influence of the environment. Moreover, this unbalanced power supply mode may gradually aggravate, resulting in the damage of battery internal structure, which makes battery pack unable to supply power, and threatens the driving and safety of electric vehicle. Researchers founded that the use of transfer battery equalization technology can solve the problem of battery stability, lack of battery life and short service life caused by the voltage problem inside the battery outside the battery. This paper described the current development stage of electric vehicle and the battery mode used, and ana lyzed the application of transfer battery equalization technology in electric vehicle.
