The present invention provides a system and method for contactor status check for an electrified vehicle. A power distribution system includes a contactor between a traction battery and a high-voltagebus. The system includes a controller configured to generate a contactor status to determine if the contactor is operating as commanded. The controller identifies a contactor as closed responsive toa rate of change of a voltage difference between a traction battery voltage and a high-voltage bus voltage over each of a predetermined number of time intervals being within a predetermined range.
本公开提供“用于电动化车辆的接触器状态检查的系统和方法”。一种配电系统包括牵引电池与高压总线之间的接触器。所述系统包括控制器,所述控制器被配置为生成接触器状态以确定所述接触器是否按命令操作。所述控制器响应于牵引电池电压与高压总线电压之间的电压差的变化率在预定数量的时间间隔中的每一个内处于预定范围内而将接触器识别为闭合。
