A method of performing a ground fault test on a plurality of battery packs of aggregated batteries of an electric work vehicle. Circuitry is configured to connect the polymeric battery to the isolation monitor. The plurality of contactors is configured to facilitate connection and disconnection of each of the plurality of battery packs to and from an electrical circuit. If the isolation monitor detects the presence of a ground fault, a user of the electric work vehicle is notified of the presence of the ground fault. And opening the plurality of contactors. 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 is a faulty battery pack. And disconnecting the faulted battery pack.

    一种对电动作业车辆的聚合电池的多个电池组执行接地故障测试的方法。电路经配置将聚合电池连接到隔离监测器。多个接触器经配置便于多个电池组中的每一个与电路的连接和从电路的断开。如果隔离监测器检测到接地故障的存在,则通知电动作业车辆的用户存在接地故障。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是故障的电池组。断开故障的电池组。
