  • System and method for managing the backup battery for an emergency call device
    Patent number: 10960837
    Abstract: A backup power supply system that is intended to be installed in a vehicle, the system includes a backup battery, a synchronous voltage step-up circuit, a user device providing an emergency service, supplied with power under normal circumstances by the main battery of the vehicle, and under exceptional circumstances by the backup battery through the voltage step-up circuit. The voltage step-up circuit includes a coil, a first transistor and a second transistor. The system includes a backup battery discharge test circuit. The first transistor is used to draw current from the backup battery according to a predefined pattern, which makes it possible, by simultaneously measuring the voltage of the backup battery, to determine an indicator of the state of health of the backup battery.
