Abstract

The invention relates to a vehicle battery temperature adjusting method and system and a vehicle. The method comprises the steps that the battery temperature is acquired; and when a braking resistor is in a feedback energy releasing process, if the battery temperature is lower than the lower limiting value of a battery work temperature interval, a cooling loop of the braking resistor is connectedinto a heating loop of a battery, and a cooling liquid circulating loop is formed by the cooling loop and the heating loop to heat the battery. According to the technical scheme, electricity generatedby feedback power in the vehicle braking process is consumed through the braking resistor, the braking performance of the vehicle is guaranteed, and meanwhile the battery can be heated through the heating quantity of the braking resistor; and therefore consumption of the electric quantity of the battery can be effectively reduced when the battery is heated, the utilization rate of the vehicle braking feedback energy is increased, and the endurance ability of the vehicle is improved.

Description

technical field [0001] The present disclosure relates to the field of vehicles, in particular, to a method, system and vehicle for regulating temperature of a vehicle battery. Background technique [0002] Vehicle batteries generally have a battery operating temperature range during normal operation. In order to ensure battery performance, it is necessary to control the battery temperature within this temperature range. Therefore, in the prior art, when the temperature of the battery is adjusted, it is necessary to provide cooling and heating equipment to ensure that the temperature of the battery is within the battery working temperature range. For example, in the prior art, when the battery is heated, the electric power of the vehicle battery needs to be consumed to convert electric energy into heat energy to heat the battery. Therefore, the battery life of the whole vehicle will be reduced. Contents of the invention [0003] In order to solve the above problems, the p...
