Abstract

The invention discloses a vehicle, and a battery heating method and system. The battery heating method of the vehicle comprises the following steps: obtaining the temperature of a power battery of the vehicle; obtaining the SOC value of the storage battery; and according to the temperature of the power battery and the SOC value of a storage battery of the vehicle, controlling the DC-DC conversion module to enter a boosting mode, in the boosting mode, controlling the DC-DC conversion module to boost a first direct current output by the storage battery so as to obtain a second direct current, and outputting the second direct current to a heating module to make the heating module heat the power battery. Therefore, due to the fact that the electric quantity of the storage battery is limited, the power battery can be prevented from being overheated or overcharged, the power battery can be safely heated, the power battery can be heated under the condition of not depending on charging equipment, and therefore the cost of the whole vehicle is saved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and a battery heating method and system thereof. Background technique [0002] Vehicles in the related art use charging equipment to heat the power battery to keep the power battery working at a low temperature. However, the problem is that this heating method relies on the charging equipment, and when the charging equipment fails, it may cause power failure. The battery is overheated or overcharged. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first purpose of the present invention is to propose a battery heating method for a vehicle, which uses battery boost to supply power to the heating module, and then heats the power battery. Since the power of the battery is limited, the power battery can be prevented from being overheated or overch...
