电动汽车蓄电池管理技术

电动汽车一般采用蓄电池组作为动力源,蓄电池组的管理问题是电动汽车发展的瓶颈。电池管理系统不可避免地存在误差问题,设计具有理想性能的电池管理系统是一件具有挑战性和吸引力的工作。分析了蓄电池的等效电路模型、荷电状态(SOC)估算方法以及电池管理系统存在的一些问题。

Management technology of electric vehicle battery

Electric vehicles (EVs) had the advantages of small noise,small emissions or almost zero emissions,the development of EVs had been of welcome to people.The battery pack was generally used by electric vehicles as power source,and battery management problem was the bottleneck of the development of electric vehicles.Error inevitably existed in the battery management system,the design of the ideal performance of the battery management system was a challenging and attractive work.In order to better understand the battery management system for beginners,the equivalent circuit model,SOC estimation method and some problems of battery management system were analyzed.
