Charging current compensation control method and device for power battery of electric vehicle

The invention provides a charging current compensation control method and device for a power battery of an electric automobile, and the method comprises the steps: judging whether the power battery of the electric automobile is in a charging state or not when the electric automobile is detected to be normally connected with a charging gun of charging equipment; if yes, whether the actual current of the battery end of the power battery is larger than the preset battery allowable current or not is judged; if yes, the control instruction value of the battery request current is set to be 1, and the current value of the battery request current is set to be the battery allowable current; and performing charging current control on the power battery according to the battery request current. Therefore, the method and the device can accurately confirm the compensation starting time, and can determine the control instruction of the battery request current in real time, so as to improve the starting and stopping accuracy
