HEV用卷式铅酸电池的性能研究

Study on the performance of spiral-wound lead acid battery for HEV

通过实验建模的方法研究了充放电倍率、环境温度和放电模式对电池容量的影响,推导出安时积分法中电流和温度补偿系数的计算公式。研究了不同温度和SOC下电池组的最大充放电性能。研究结果表明:卷式铅酸电池具有良好的充放电性能,适用于混合电动汽车(HEV)。

The effects of charge-discharge rate, environmental temperature and discharge mode on the capacity of the battery were studied by the method of modeling in experiment, deducing the formula of current and temperature compensation coefficients within the ampere-hour integral method. The maximal charge-discharge performance of the batteries under different temperatures and SOC conditions was studied. The research results showed that spiral-wound lead acid battery had fine charge-discharge performance, it was suitable for HEV.
