摘要
在快速充电技术的研究中,一个首要的任务就是确定蓄电池荷电状态(SOC),为快速充电控制提供参数依据。传统的充/放电循环测定法会使蓄电池老化,降低蓄电池内部化学物质的活性,导致内阻增加,缩短其使用寿命。文章介绍了一种基于最小二乘算法的电动势-内阻方法来测定蓄电池的荷电状态,这种方法可以应用于在线测定,并且无需深度放电再充电,从而延长了蓄电池的使用寿命。经实验验证这种方法是有效的。
Determining the state of charge (SOC) of a battery is an essential in fast charging compositi controlling. A battery is on of the battery result in aged by charging and discharging cycles. charging, it provides parametes in fast This process degrades the Chemical shortening the life .This paper describes a Electromotive force-impedance test to determine the SOC of battery based on the least squares analysis. It doesn't need full discharging, and then increase the life of the battery. The new approach is fully validated by experiments.
