Abstract

The invention discloses an energy control method and device of an electric vehicle and the electric vehicle. The problems that in the existing energy control process, the electric energy of a battery cannot be fully utilized, the capacity of electric equipment cannot be exerted, and effective and efficient distribution of available electric energy cannot be achieved are solved. The method comprises the steps that the required power of electric equipment of the electric vehicle, the maximum output power of a vehicle-mounted charger and working parameters of a power battery are obtained, the working parameters comprise charging capacity information and discharging capacity information of the power battery, and the electric equipment comprises a low-voltage electric appliance and a heater of the power battery; based on the working parameters of the power battery, the required power of the electric equipment and the maximum output power of the vehicle-mounted charger, the output power of the vehicle-mounted charger is controlled; and based on the output power of the vehicle-mounted charger, the working parameters of the power battery and the required power of the electric equipment, the working power of the power battery and the working power of the electric equipment are controlled.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular to an energy control method and device for an electric vehicle and the electric vehicle. Background technique [0002] Electric vehicles use battery power instead of traditional vehicles to burn petroleum, which has the advantages of environmental friendliness, no pollution, strong acceleration, and no noise. However, the charge and discharge capacity of the battery is strongly related to the battery temperature, which changes with the change of power and temperature. Compared with traditional fuel vehicles, electric vehicles have more electrical equipment. During the charging process, especially in the In the case of low temperature and low power, the capacity of the battery is extremely limited. If the battery or the electric energy from the charging pile cannot be reasonably distributed, the battery will be overcharged or overdischarged, thereby affecting the servi...
