A battery system includes a battery pack configured to be selectively connected to an output terminal of the battery system and a DCFC receptacle, a first contactor that is connected between the DCFC receptacle and a first terminal of the battery pack, and a first SSR connected in series with the first contactor between the DCFC receptacle and the first terminal of the battery pack. The first SSR has an open state where current from the DCFC receptacle to the battery pack is interrupted and a dosed state where current flows from the DCFC receptacle to the battery pack, the first SSR is configured to transition from the dosed state to the open state prior to the first contactor, and current only flows from the DCFC receptacle to the battery pack when both the first contactor and the first SSR are in the closed state.
