Abstract
A battery power supply system and a battery power supply method for a main system are provided. The battery power supply system includes a power supply processor, an expansion slot module with plural slots, and plural battery units. The plural battery units are docked with the corresponding slots. Moreover, plural control switches are electrically connected between the corresponding slots and the power supply processor. A voltage value of one battery unit is defined as a fiducial voltage value. If the difference between the fiducial voltage value and the voltage value of at least one battery unit of the rest of the battery units is within a predetermined value, the control switch corresponding to the at least one battery unit is turned on. The battery unit with the fiducial voltage value and the at least one battery unit are connected with each other in parallel.
