Abstract
The smart battery includes an electronic circuit for managing the supply voltage connected to a battery. The electronic circuit includes a battery end-of-life detector, a management unit, an oscillator stage, a DC-DC converter powered on when the supply voltage of the battery is close or equal to a battery end-of-life threshold, and a data or command communication interface. The data or command communication interface is a 1-wire interface which is connected to a positive supply voltage terminal of the smart battery for transmitting a modulated data or command signal through one of the supply voltage terminals. The modulated signal transmitted by the interface may include battery end-of-life information.
