Classification: CPC B  H  G  Y | IPC B  G  H

Claim 12:
13. An apparatus comprising:
a battery;
circuitry including a primary switching circuit electrically coupled to a terminal of the battery, the primary switching circuit comprising, an electromechanical switching device configured to, when in a first closed position, enable current in a first direction through the primary switching circuit to facilitate charging the battery, and enable current in a second direction through the primary switching circuit to facilitate discharging the battery; and
the circuitry further including a secondary switching circuit electrically coupled to the terminal of the battery in parallel with the primary switching circuit, the secondary switching circuit comprising solid-state switching devices being configured to enable current in only one of the first direction and the second direction through the secondary switching devices when the secondary switching circuit is in a closed configuration; and
a battery control system operatively coupled to the primary switching circuit and the secondary switching circuit to test, operation of the circuitry, the battery control system being configured to determine target current to be supplied from the battery 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 secondary switching circuit to maintain the closed configuration to facilitate supplying electrical power at the target current from the battery 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.
