Claim 6:
7. A method comprising:
operating an automotive vehicle including a battery cell and circuitry including an electromechanical switching device coupled to a terminal of the battery cell and a semiconductor switching device coupled to the terminal of the battery cell in parallel with the electromechanical switching device;
enabling current in a first direction through the electromechanical switching device to discharge the battery cell;
enabling current in a second direction through the electromechanical switching device to charge the battery cell;
limiting current through a solid-state switching device in one of the first direction and the second direction with a diode electrically coupled in series with the solid-state switching device when the solid-state switching device is in closed position;
testing operation of the circuitry with a battery control system operatively coupled to the solid-state switching device;
determining a target power output from the battery cell;
maintaining an open position of the electromechanical switching device when the target power is less than or equal to a power threshold; and
if the target power exceeds the power threshold, maintaining a closed position of the electromechanical switching device.
