Document Type and Number:
WIPO Patent Application WO/2020/195780
Kind Code:
A1
Abstract:
A protection device 120 for an electricity storage element 62 comprises: a current interrupter 53 that interrupts the current of the electricity storage element 62; and a control unit 130. The present invention has a plurality of conditions with different current threshold values and cumulative threshold values. The control unit 130 calculates a cumulative value N of time during which the current exceeds any of the current threshold values Is and executes a current cutoff process S150 for interrupting the current when the calculated cumulative value N exceeds a cumulative threshold value Ns associated with the current threshold value Is.
