Abstract
A protective apparatus of an energy storage device includes a current breaker that interrupts the current of the energy storage device, and a control part. There are a plurality of conditions having different current thresholds and cumulative thresholds, and the control part calculates a cumulative value N of times during which the current exceeds any one of the current thresholds Is, and executes current interruption processing of interrupting the current when the calculated cumulative value N exceeds one of the cumulative thresholds Ns associated with the current threshold Is.
