1. An automotive vehicle comprising:
a battery cell;
circuitry including a primary switching device electrically coupled to a terminal of the battery cell, the primary switching device comprising an electromechanical switching device configured to, when in a first closed position:
enable current in a first direction through the primary switching device to facilitate charging the battery cell; and
enable current in a second direction through the primary switching device to facilitate discharging the battery cell; and
the circuitry further including a secondary switching device electrically coupled to the terminal of the battery cell in parallel with the primary switching device, the secondary switching device comprising:
a solid-state switching device; and
a diode electrically coupled in series with the solid-state switching device, the diode being configured to enable current in only one of the first direction and the second direction through the secondary switching device when the solid-state switching device is in a second closed position; and
a battery control system operatively coupled to the secondary switching device to test operation of the circuitry, the battery control system being configured to
determine target current to be supplied from the battery cell to an electrical device electrically coupled to the primary switching device and the secondary switching device; and
when the target current is less than a first current threshold:
instruct the solid-state switching device to maintain the second closed position to facilitate supplying electrical power at the target current from the battery cell to the electrical device; and
instruct the electromechanical switching device to maintain a first open position to facilitate limiting supply of electrical power to the electrical device.
