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

A safety device () for a lithium electrochemical generator battery, including a box (), configured to house a plurality of lithium electrochemical generators; a cover () arranged gas-tightly on the opening () of the box; an opening () forming a vent situated in one of the walls of the box () or situated in the cover (); a conduit () having two openings () where one of the openings () is gas-tightly connected to the opening () forming a vent of the box; a covering part () positioned gas-tightly at an opening of a wall of the compartment and the second opening () of the conduit, and where said covering part comprises a portion () adapted to tear at a threshold pressure Ps; where the walls of the box, the cover, the conduit and the covering part are secured to each other so as to ensure sealing against the gases up to a pressure above the threshold pressure Ps.
