The system also includes a sensor to detect when the backup battery should be engaged and a system control unit.
Claims1
A reserve power supply system, said system comprising:
- a first battery;
- an electrical interface adapted for being coupled to a second battery;
- a control unit;
- a switch coupled to said first battery, to said electrical interface and to said control unit, said switch being controlled by said control unit;
- a voltage sensor coupled to said control unit and to said electrical interface, said voltage sensor being adapted for measuring the voltage across said second battery when said second battery is coupled to said electrical interface and providing a corresponding voltage sensor signal to said control unit, wherein when said voltage sensor signal is below a predetermined value, said control unit controls said switch to coupled said first battery to said electrical interface.
