ACCUMULATOR BATTERY PROTECTED AGAINST EXTERNAL SHORT-CIRCUITS

摘要

The invention relates to a power battery (21), comprising: electrochemical accumulators connected in series between two output terminals (B1, B2) of the battery; - a breaker (41) making it possible to selectively isolate one of the output terminals from an electrical load; a circuit (24) for detecting an external short-circuit, to which the voltage between the output terminals of the battery is applied, the detection circuit being configured to: compare the voltage applied with a voltage threshold representative of a short-circuit; generate an opening signal for said breaker (41) when the voltage applied becomes less than said threshold.
