Abstract: A method for calculating a resistance of an internal short circuit in a battery is provided, which includes the following steps. Multiple voltage-capacity curve samples of a battery under multiple stable current charging and/or discharging conditions are obtained. The charge and/or discharge data of the battery are measured, and the charge and/or discharge data at least includes a charging voltage sequence and a charging current sequence, and/or a discharge voltage sequence and a discharge current sequence. The charge and/or discharge data of the battery is compared with at least one reference curve in the voltage-capacity curve samples to determine whether the battery is charging and/or discharging normally. When the charge and/or discharge data of the battery deviates from the reference curve, a leakage current and a leakage resistance of the battery are calculated.
