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.

Safety device for a lithium electrochemical generator battery

An electronic system for a battery designed to supply electrical power to an application, such as in an aircraft, that includes a main power supply, comprises a charging circuit () with a charger (KC), a first battery discharging circuit () in parallel with the charging circuit, a component ensuring continuity of discharge (D) and an electronic control unit adapted to control opening and closing of the discharge switch (K) and adapted to control said charger (KC). The control unit keeps the battery charged as long as it is not being called on to discharge and interrupts battery charging and sets the discharge switch (K) to the closed position when a call for power is detected from the application, the component ensuring continuity of discharge (D) allowing passage of a discharge current during a transitional phase of closing of the discharge switch (K).

Electronic system for a battery

An electronic system for a battery comprises a charging circuit () for the battery connected to a connector powering the charging circuit (), a control and monitoring circuit () for the operation of the battery, and a discharge circuit connected to power connectors () of the battery. The control and monitoring circuit () interrupts battery charging when there is a call for current via the power connectors () of the battery. The electronic system has application to rechargeable batteries used to provide back up power.
