A battery system includes first and second battery packs connected to positive and negative DC voltage bus rails, a contactor switch connected between the battery packs, a solid-state switch in series with the contactor switch, and a controller. The controller determines characteristic values of the switches, including a respective temperature, voltage, and current value for each. The controller also detects a predetermined electrical fault condition of the contactor switch using the characteristic values, and executes a control action in response to the electrical fault condition. The control action includes opening the semi-conductor switch to thereby interrupt a flow of current between the first and second battery packs. A mobile platform includes road wheels connected to a body, a rotary electric machine configured to power the road wheels and thereby propel the mobile platform, and the battery pack, switches, and controller.
