Abstract:
1. A battery status detection method for an electronic device, a battery module being pluggable into the electronic device, the battery module stopping outputting a battery voltage when a residual charge quantity of the battery module is lower than a threshold charge quantity, the battery status detection method comprising steps of: judging whether the battery module is in a plugged status or an unplugged status according to the battery voltage; if the battery module is in the unplugged status, periodically charging the battery module in a first time interval of a fixed cycle while said battery module remains connected to said electronic device until the residual charge quantity of the battery module is higher than the threshold charge quantity and the battery voltage is outputted from the battery module; and if the battery module is in the plugged status, judging whether the battery module is in the unplugged status according to a change of the battery voltage.
