An electronic connecting/disconnecting device for a high voltage unit for storing electrical energy designed to be charged and discharged asymmetrically, in particular a battery arranged as part of an electrical circuit is provided. The device includes a charging switch and a discharge switch arranged in parallel and dimensioned asymmetrically for charging and discharging the unit for storing electrical energy, the charging switch being adapted to block, in a first direction of passage, an electric current flowing therethrough, this first direction of passage being opposite to a second direction of passage in which the discharge switch is adapted to block an electric current passing therethrough, the device being able to be activated when a physical magnitude of an electrical current flowing through the circuit is greater than a predetermined threshold.

Electronic connect/disconnect device and method for a high voltage battery

The invention relates to an electric energy storage system, comprising an inverter (), several associations (), of an electric energy storage unit () in series with a bidirectional chopper (), connected in parallel to a same input of the inverter (), on the side of their chopper (), characterized in that at least one bidirectional chopper (), associated with an electric energy storage unit () that can be charged and discharged asymmetrically, is sized asymmetrically for the charge and discharge of said associated storage unit ().
