A method of performing a ground fault test on an aggregated battery for an electric work vehicle. The polymeric battery is not connected to the electric work vehicle and includes a plurality of battery packs. The plurality of contactors is configured to facilitate connection to and disconnection from a circuit of each of the plurality of battery packs. The ground fault detection tool is connected to the circuit and battery management system service tool. If the isolation monitor detects the presence of a ground fault, the plurality of contactors are opened. Closing of the plurality of contactors is ranked to sequentially include each of the plurality of battery packs in a circuit having an isolation monitor. The isolation monitor is used to determine whether the battery pack included in the circuit includes a faulty battery pack. And disconnecting the faulted battery pack.

    一种对用于电动作业车辆的聚合电池执行接地故障测试的方法。聚合电池不连接到电动作业车辆,并且包括多个电池组。多个接触器经配置便于连接到电路和从多个电池组中的每一个的电路断开。接地故障检测工具连接到电路和电池管理系统服务工具。如果隔离监测器检测到存在接地故障,则打开多个接触器。对多个接触器的闭合进行排序,以将多个电池组中的每一个依次包括在具有隔离监测器的电路中。隔离监测器用于确定包括在电路中的电池组是否包括故障的电池组。断开故障的电池组。
