Patent ID: 8253277

Claim:
An electronic assembly adapted to be coupled electrically to a first battery unit and a second battery unit, the electronic assembly comprising: a system module provided with a threshold value; a parallel circuit coupled electrically to said system module, and including a first power diverter circuit consisting of a first diode member that is electrically coupled to the first battery unit and said system module in such a manner that a first normal bias voltage is existed between the first battery unit and said system module and a first operation switch that is coupled electrically to said first diode member in parallel manner and that is coupled electrically to the first battery unit and said system module, and a second power diverter circuit consisting of a second diode member that is electrically coupled to the second battery unit and said system module in such a manner that a second normal bias voltage is existed between the second battery unit and said system module, and a second operation switch that is coupled electrically to said second diode member in parallel manner and that is coupled electrically to the second battery unit and said system module; wherein, when the electronic assembly is in a first power supply condition, a first current is supplied via said first diode member to said system module, which, transmits a first switch signal and a second switch signal to said first operation switch and said second operation switch respectively, thereby switching said first operation switch ON and switching said second operation switch OFF in order to supply the first electrical power to said system module via said first operation switch; wherein, when a second current is greater than said threshold value, said system module is capable of transmitting said first switch signal and said second switch signal to said first operation switch and said second operation switch respectively, thereby switching said first operation switch OFF and switching said second operation switch ON to convert the electronic assembly into a second power supply condition, where the second electrical power is supplied to said system module via said second operation switch.
