Abstract
A detecting device used to detect storage capacity of a battery is connected to a load by a first output terminal and a second output terminal. The detecting device includes a switch unit, a detecting unit, and a control unit. The switch unit is connected between the first and second output terminals. The detecting unit is connected to the first and second output terminals. The detecting unit detects output voltage and current of the battery when the switch is turned on and off and obtains an internal resistance of the battery according to the detected output voltage and current. The control unit controls the switch unit to turn on and off and compares the detected resistance with a reference resistance, and determines the storage capacity of the battery according to the comparison.
