DISPLAYED POWER CORRECTION METHOD AND DEVICE

A displayed power correction method, adapted to a target battery with a battery temperature lower than a threshold temperature, is performed by a controller (11) and includes: determining whether the target battery is a first type battery or a second type battery according to designed power of the target battery, lowering displayed power according to a first default rate of the first type battery when the target battery is the first type battery and a battery cell voltage of the target battery is lower than a threshold voltage, and lowering displayed power according to a second default rate of the second type battery when the target battery is the second type battery and a capacity parameter or a voltage parameter of the target battery is higher than a default value.
