ELECTRICAL SYSTEM FOR PRECHARGING A CAPACITY ARRANGED BETWEEN POSITIVE AND NEGATIVE LINES CONNECTABLE TO A BATTERY

Abstract

The invention relates to an electrical system (10) comprising an electric battery having a positive terminal (11) and a negative terminal (12), a first positive line (L1), a second negative line (L2), a first contactor (S1) interposed between the positive terminal and the first line (L1), a second contactor (S2) interposed between the negative terminal and the second line, a reservoir capacity (CR) interposed between the first line and the second line, the system comprising a precharging circuit, connected on the one hand to the first line and on the other hand to the positive terminal, the precharging circuit comprising in series an inductance (LPC) and a control transistor (T1) configured to be controlled by a control unit (4), the control transistor being controlled, after closing the second contactor and before closing the first contactor, according to a pumping cycle control to charge the reservoir capacity.
