Abstract

The invention discloses a vehicle and a heating method and device for a battery pack of the vehicle. The heating method comprises the following steps: obtaining the temperature of a battery pack after a vehicle is started, and carrying out the judgment; if the temperature of the battery pack is lower than a preset temperature, generating a heating instruction; and sending the heating instruction to a microcontroller, so that the microcontroller outputs current to the motor of the vehicle according to the heating instruction, a motor rotor is kept static, and a motor winding emits heat so as to heat the battery pack. According to the method, heating of the battery can be achieved through heat generated by the motor before the vehicle is started, the situation that the battery pack cannot run due to the too low temperature is avoided, normal starting of the vehicle is guaranteed, other components are not needed, and cost is low.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for heating a battery pack of a vehicle, a heating device for a battery pack of a vehicle, and a vehicle. Background technique [0002] At present, in order to solve the shortage of global oil resources and the problems of urban air pollution, new energy vehicles including hybrid and pure electric technologies are booming. , may cause the battery to fail to function properly, which in turn may cause the vehicle to fail to start normally. [0003] Therefore, it is imperative to develop the heating function of the battery pack when it operates in a low temperature environment. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, the first object of the present invention is to propose a method for heating the battery pack of a vehicle, which can ...
