A power control system for a battery system of a vehicle includes a first contactor, a second contactor, N fuses, and N vehicle loads. The active sacrificial protection device includes a third contactor and a first fuse. The active sacrificial protection device is connected to the anode or cathode of the battery system. The current sensor is configured to sense a measured load current flowing through one of the first contactor and the second contactor. The battery management module is configured to selectively close the third contactor to reduce current flowing through one of the first contactor or the second contactor, and to selectively open the one of the first contactor or the second contactor after closing the third contactor.

    一种用于车辆的电池系统的动力控制系统包括第一接触器、第二接触器、N个熔断器和N个车辆负载。主动牺牲保护设备包括第三接触器和第一熔断器。主动牺牲保护设备连接到电池系统的正极或负极。电流传感器配置为感测流动通过第一接触器和第二接触器中的一者的测量的负载电流。电池管理模块配置为选择性地闭合第三接触器以减少流动通过第一接触器或第二接触器中的一者的电流,并且在闭合第三接触器之后选择性地断开第一接触器或第二接触器中的该一者。
