The invention provides a battery temperature control method and a vehicle, the control method is used for a thermal management system of the vehicle, and the thermal management system comprises a cooling liquid loop and a switching valve. The cooling liquid loop comprises a first sub-cooling liquid loop and a second sub-cooling liquid loop. The switching valve is connected between the first sub cooling liquid loop and the second sub cooling liquid loop and comprises a first state and a second state. The first sub-coolant loop includes a battery, and the second sub-coolant loop includes an electrical component. The control method comprises: acquiring the temperature of a battery; and controlling the switching valve to operate according to the temperature of the battery. And if the temperature of the battery is higher than the first set temperature, the switching valve is controlled to be switched to a first state, so that the first sub cooling liquid loop and the second sub cooling liquid loop are separated. And if the temperature of the battery is smaller than the second set temperature, the switching valve is controlled to be switched to the second state, so that the first cooling liquid sub-loop and the second cooling liquid sub-loop are connected. The first set temperature is greater than or equal to the second set temperature. The cooling speed is high.

    本申请提供一种电池温度的控制方法及车辆,控制方法用于车辆的热管理系统,热管理系统包括冷却液回路和切换阀。冷却液回路包括第一子冷却液回路和第二子冷却液回路。切换阀连接于第一子冷却液回路和第二子冷却液回路之间、且包括第一状态和第二状态。第一子冷却液回路包括电池,第二子冷却液回路包括电气组件。控制方法包括:获取电池的温度。根据电池的温度,控制切换阀运作。若电池的温度大于第一设定温度,控制切换阀切换至第一状态,以使第一子冷却液回路和第二子冷却液回路分离。若电池的温度小于第二设定温度,控制切换阀切换至第二状态,以使第一子冷却液回路和第二子冷却液回路连接。第一设定温度大于等于第二设定温度。降温速度快。
