摘要
动力电池峰值功率对于电动汽车动力匹配优化和合理设计电池管理系统控制策略具有重要的理论意义。本文提出峰值功率估计-恒功率充放电验证的测试方法,并以铅酸动力蓄电池为例测试常温25℃下电池不同SOC点的峰值功率。结果表明,恒压充放电法得到的峰值功率估计值与最终结果相吻合,该方法可以便捷地测试不同持续时间的电池峰值功率。
It is very important to study peak power of power battery for the optimization of matched dynamic parameter of EV and the reasonable design of battery manage system. A method of peak power estimation-constant power charging and discharging verification is present in this paper. The peak power of lead-acid in different SOC under the normal temperature （25℃） is tested as an example. The result shows that the estimation value of peak power from constant voltage test is consistent with the final result, so this test method is effective and convenient.
