A protection system for a high voltage component includes a switching circuit and a protection controller. A switching circuit changes a variable arrangement of the plurality of battery packs between a parallel arrangement and a series arrangement. The protection controller commands the switching circuit to enter the series arrangement in response to the recharging session, commands current flow in the recharging session, measures a measured voltage between the input node of the high voltage component and the floating chassis ground, advances the timer when the measured voltage indicates that there is an inappropriate voltage, and recharges the high voltage component. And cancelling the recharging session in response to the presence of an inappropriate voltage greater than the exposure time. The recharge session provides a DC fast charge voltage to the battery pack in the series arrangement, and the DC fast charge voltage is greater than the battery voltage.
用于高压部件的保护系统包括开关电路和保护控制器。开关电路在并联布置和串联布置之间改变多个电池组的可变布置。保护控制器响应于再充电会话而命令开关电路进入串联布置,命令再充电会话中的电流流动,测量高压部件的输入节点与浮动底盘接地之间的测量电压,在测量电压指示存在不适当的电压时使计时器前进,以及响应于存在不适当的电压大于暴露时间而取消再充电会话。再充电会话向串联布置中的电池组提供直流快速充电电压,并且直流快速充电电压大于电池电压。
