description A battery module power supply management method is applied on a battery module which supplies electric power to a load. The battery module comprises N battery units (N>=2), N linear adjustors, and N switches which are correspondingly coupled between the N battery units and the N linear adjustors electrically in one-to-one manner. Output ends of the N linear adjustors are parallelly connected and are electrically coupled with a load. The battery module power supply management method comprises the steps of firstly controlling the N switches for totally conduction so that an output current of each battery unit is output through the output end of the corresponding linear adjustor; gathering the output currents of the battery units for obtaining a total current and supplying to the load; acquiring the output current of the N battery units, and controlling for realizing conduction of M switches in the N switches on condition that a fact that the total current of the output currents is smaller than M times of the rated current of the battery units and is larger than (M-1) times of the rated current, wherein 2
