1. A management apparatus for an energy storage device used for activating a drive source, the management apparatus comprising:
a management part that operates by power supplied from the energy storage device;
a backup power source that supplies power to the management part when a voltage of the energy storage device decreases;
a circuit breaker connected in series with the energy storage device; and
a current sensor that detects a current value of a current flowing through the energy storage device,
wherein the management part turns off the circuit breaker when a current value equal to or larger than a predetermined value is detected by the current sensor.
