The embodiment of the invention is suitable for the technical field of vehicles, and provides a vehicle battery temperature control method and a vehicle, and the method comprises the steps: if the current temperature of a battery in the vehicle is not within a preset temperature range, determining a target control value of a temperature adjusting device in the vehicle according to the target temperature and the current temperature of the battery; a target fan duty ratio of a fan and a target water pump duty ratio of a water pump in the heat dissipation system; the target control value is corrected based on the current environment temperature of the vehicle and the temperature change rate of a water outlet of cooling liquid of the heat dissipation system; and controlling a temperature adjusting device according to the corrected target control value so as to adjust the temperature of the battery. Through the method, the temperature of the vehicle battery can be controlled more accurately.
本申请实施例适用于车辆技术领域,提供了一种车辆电池温度的控制方法及车辆,该方法包括:若车辆中电池的当前温度不在预设的温度范围内,则根据电池的目标温度和当前温度,确定车辆中温度调节装置的目标控制值;散热系统中风扇的目标风扇占空比和水泵的目标水泵占空比;基于车辆所处的当前环境温度和散热系统的冷却液的出水口温度变化速率,对目标控制值进行校正;根据校正后的目标控制值,对温度调节装置进行控制,以调节电池的温度。通过上述方法,能够更精准地对车辆电池的温度进行控制。
