Two ends of the current control unit are connected to a battery and a charging power supply, respectively. The method includes controlling, when a temperature of the battery is below a preset temperature, the current control unit to be in a first state in which the semiconductor device is reversely connected in a circuit, sending a first charging request including a first charging current required to heat the battery to the preset temperature, controlling, when the temperature of the battery reaches the preset temperature, the current control unit to be in a second state in which the semiconductor device is disconnected from the circuit or forwardly connected in the circuit, and sending a second charging request including a second charging current at which the battery is charged.",
