By implementing the optional implementation mode, before the vehicle is controlled to return the electric energy stored in the vehicle battery to the charging parking space, whether the electric quantity of the battery is larger than a first preset electric quantity or not is detected, if the electric quantity is smaller than or equal to the first preset electric quantity, it is indicated that the sound residual electric quantity of the battery of the vehicle is insufficient, the vehicle is forbidden to release the electric energy of the battery through the wireless transceiving coil, and the normal electric energy supply of the vehicle can be ensured.

205. The vehicle battery management system controls the vehicle to receive the electric energy of the power grid transmitted by the charging parking space through the wireless transceiving coil so as to convert the electric energy of the power grid into electric energy of the battery and store the electric energy of the battery in the vehicle.

By implementing the optional implementation mode, before charging the battery of the vehicle, whether the electric quantity of the battery is smaller than the second preset electric quantity is detected, if the electric quantity is larger than or equal to the second preset electric quantity, the residual electric quantity of the battery of the vehicle is still sufficient, the vehicle is forbidden to receive the electric network electric energy transmitted by the charging parking space through the wireless transceiving coil, and the waste of the electric energy can be avoided.

It can be seen that, by implementing the method described in fig. 2, by making the vehicle participate in power consumption regulation, when the power consumption peak is reached, the grid voltage is reduced, and when it is detected that the grid voltage is lower than the preset voltage value, the vehicle is controlled to return the electric energy stored in the vehicle battery to the charging parking space, so that the charging parking space converts the electric energy of the battery into the grid electric energy with proper frequency and voltage, and the contradiction between the power demand of people and the power failure during the power consumption peak can be effectively alleviated; in the non-electricity-consumption peak period, the voltage of the power grid is increased, and when the fact that the voltage of the power grid is higher than or equal to a preset voltage value is detected, the vehicle is controlled to receive the power grid electric energy emitted by the charging parking space for charging. In addition, when the vehicle drives into the parking space that charges, owing to adjust the distance to the appointed distance between the wireless transceiver coil of vehicle and the wireless transceiver coil of parking space that charges in advance, need not the manual work and carry out loaded down with trivial details pulling out and inserting the rifle that charges, can carry out wireless discharge and charge, raise the efficiency.
