The invention provides a battery pack driving heating control method and device, a battery pack and an electric vehicle, and relates to the technical field of electric vehicles. The method comprises the steps that the average vehicle speed of a vehicle in a preset time period is acquired; acquiring the current temperature of the battery pack, a first temperature rise rate at which the temperature of the battery pack rises by a preset value, and the state of charge of the battery pack; obtaining a target driving mileage of the vehicle; determining the target temperature of the water inlet of the battery pack heating device according to the average vehicle speed of the vehicle within the preset time period, the first temperature rise rate, the state of charge of the battery pack and the target driving mileage; and controlling the temperature of the battery pack according to the target temperature. According to the scheme, the problems that the heating time point of the battery cannot be started and the heating power of the battery cannot be determined due to the fact that the heating of the battery cannot be adjusted in time through the temperature rise rate of the battery and the driving dynamic time in the prior art are solved.

    本发明提供了一种电池包行车加热控制方法、装置、电池包及电动汽车,涉及电动车技术领域。该方法包括:获取车辆在预设时间段内的平均车速;获取所述电池包的当前温度、所述电池包温度升高预设值的第一温升速率以及所述电池包的荷电状态;获取车辆的目标行驶里程;根据所述车辆预设时间段内的平均车速、所述第一温升速率、所述电池包的荷电状态以及所述目标行驶里程,确定所述电池包加热装置入水口的目标温度;根据所述目标温度,控制所述电池包的温度。本发明的方案解决了现有技术中无法通过电池的温升速率和行车动态时间及时调整对电池的加热,导致无法开始对电池进行加热的时间点,且无法确定对电池进行加热的功率的问题。
