Abstract
A power supplying system includes multiple rechargeable battery devices each including a first switch module, a series connection of a battery unit which includes multiple rechargeable batteries connected in series with each other and a second switch module connected in parallel to the first switch module, and a control module for controlling operations of the first and second switch modules. For each rechargeable battery device, the first and second switch modules are normally operated in an OFF-state and an ON-state, respectively, and the control module enables the first and second switch modules to switch respectively from the OFF-state and the ON-state to an ON-state and an OFF-state upon detecting that a voltage of any one of the rechargeable batteries of the battery unit is not within a predetermined voltage range during charging or discharging of the battery unit.
