In the embodiment of the invention, in order to determine the environmental temperature of the environment where the power supply to be detected is located, the temperature signal data acquired by the temperature sensor needs to be acquired first, and then the temperature signal data is converted into the environmental temperature (the unit is c) of the environment where the power supply to be detected is located by using a preset formula.

After the environment temperature of the environment where the power supply to be detected is located is determined, deviation data (namely target data) between a cold start current value for representing the environment temperature and a cold start current value at 25 ℃ is determined by inquiring a preset table, and the target data is determined as an adjustment coefficient.
