Abstract
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.
