The invention relates to a method and device for controlling vehicle charging and a vehicle. When it is detected that a charging gun is inserted into a charging socket of the vehicle, a battery pack controller is controlled to obtain the battery pack temperature collected by a temperature sensor; the battery pack controller is used for sending the temperature of the battery pack to the vehicle control unit, controlling the heating assembly to heat the battery pack under the condition that the temperature of the battery pack is smaller than or equal to a second preset temperature threshold value, and controlling the heating assembly to stop heating the battery pack when the temperature of the heated battery pack is larger than the second preset temperature threshold value; the vehicle control unit is further used for charging the battery pack through the battery pack controller when it is determined that the battery pack temperature sent by the battery pack controller is larger than or equal to a first preset temperature threshold value; wherein the first preset temperature threshold value is smaller than the second preset temperature threshold value, so that the battery pack is flexibly controlled to be charged and heated, and the charging efficiency of the vehicle battery pack is improved.

    本公开涉及一种控制车辆充电的方法、装置以及车辆,在检测到充电枪插入车辆的充电插口时,控制电池包控制器获取温度传感器采集的电池包温度;电池包控制器用于将电池包温度发送至整车控制器,并在电池包温度小于或者等于第二预设温度阈值的情况下,控制加热组件加热电池包,在加热的电池包温度大于第二预设温度阈值时,控制加热组件停止加热电池包;整车控制器还用于在确定电池包控制器发送的电池包温度大于或等于第一预设温度阈值时,通过电池包控制器为电池包进行充电;其中第一预设温度阈值小于第二预设温度阈值,从而灵活地对电池包进行充电和加热的控制,提高车辆电池包的充电效率。
