Abstract

The invention discloses a control method of an electric automobile and the electric automobile. The method includes the steps that a vehicle control unit obtains the current temperature value of a power cable, and the power cable is used for connecting a power battery with a load system; and when the current temperature value exceeds a preset temperature, a control command is sent to the load system, so that the load system reduces the current of electric energy supplied by the power battery to a load according to the control command. The power of the load is controlled through the vehicle control unit, so that the current of the load is reduced, the temperature rise of the power cable is reduced, under the condition that the temperature of the power cable is controlled, the size of the power cable can be reduced, and therefore cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle control method and the electric vehicle. Background technique [0002] In the prior art, electric vehicles usually provide electric energy through power cables. Due to the large current, if the cross-sectional area of ​​the power cable is small, the temperature of the power cable will easily rise when the current is large, causing the The cable insulation layer of the power cable may dissolve, causing the wires of the power cable to be exposed, which may easily cause safety accidents. If a power cable with a larger cross-sectional area is used, the temperature rise of the power cable can be reduced, but it will increase the manufacturing cost and cannot be realized. Miniaturization of electric vehicles. Contents of the invention [0003] The main purpose of the present invention is to provide a control method for an electric vehicle and the electr...
