摘要
储能锂电池组串由大量锂电池串并联组成,由于其电压高、电流大、容量大,无法使用电动汽车锂电池模组容量试验方法。描述了储能锂电池组串容量的定义,分析了充放电倍率、温度、充放电截止电压对锂电池容量试验的影响,比较了锂电池容量试验标准,并根据不同厂家电池组串容量试验方法,提出了一种具有通用性的储能锂电池组串现场容量试验方法,该试验方法对储能电池维护工作具有指导作用。
Energy storage lithium battery cluster is made up by a large number of batteries in series or in parallel Due to its high voltage, large current and high capacity, the energy storage lithium battery cluster cannot be tested for capacity by EV battery module. This paper introduces the definition of energy storage lithium battery cluster capacity, discusses the influences of the charge-discharge rate, ambient temperature, charging and discharging cut-off voltage on the capacity test of the lithium battery cluster, and compares the test standards for lithium battery capacity. Finally, a novel universal field capacity testing method is proposed for energy storage lithium battery cluster according tothe field capacity testing methods of several manufacturers, which will be helpful for the maintenance of energy storage batteries.
