A battery element includes series-connected electrochemical accumulators applying a difference in potential between first and second poles, two power output terminals, and a securing device. The securing device comprises first and second switches connected in series between the first and second poles. The first switch is a normally-closed switch, and the second switch is a normally-open switch. The normally-open second switch is configured to selectively isolate/connect the first pole and the first terminal, and the normally-closed first switch being configured to selectively isolate/connect the first and second terminals. The electrochemical accumulators are configured to apply a voltage as a control signal for the normally closed first switch.
