Abstract
A power supply apparatus includes a controller. If the controller detects that the internal resistance of a battery detected by an internal resistance detecting unit is relatively high, then the controller switches a first switch from an open state to a closed state using a first threshold value with respect to the voltage difference between a battery voltage and a system voltage, and if the controller detects that the internal resistance of the battery is relatively low, then the controller switches the first switch from the open state to the closed state using a second threshold value which is smaller than the first threshold value.
