The invention provides a heating control method and device for an electric vehicle, a vehicle and a storage medium. The method comprises the steps that when a battery heating request sent by a battery management system is received and it is judged that the electric vehicle cannot start range extending type battery heating at present, the battery heating request is sent to the battery management system; judging whether the battery is in a low-temperature state or not based on the current charge state data and the current temperature value of the battery; if yes, a heating device in the electric vehicle is controlled to conduct pure electric battery heating on the battery; and if not, when it is judged that the passenger compartment needs to be heated preferentially according to the water temperature of the warm air inlet of the passenger compartment and the power of the water heater of the electric automobile, the heating function of the battery is closed, so that the passenger compartment is heated preferentially. By means of the method and device, the heating requirements of the passenger compartment and the battery are balanced, energy distribution of passenger compartment heating and battery heating is adjusted, the comfort of passengers is met, meanwhile, it is ensured that the temperature of the battery can be within a proper temperature interval, and the dynamic property requirement of a vehicle is met.

    本申请提供了一种电动汽车的加热控制方法、装置、车辆及存储介质,所述方法包括:当接收到电池管理系统发送的电池加热请求,且判断电动汽车当前不能开启增程式电池加热时,基于电池的当前荷电状态数据和当前温度值判断电池是否处于低温状态;若是,则控制电动汽车内的加热装置对所述电池进行纯电式电池加热;若否,则当根据乘员舱暖风入口水温和电动汽车的水加热器的功率判断乘员舱需要优先加热时,关闭对电池的加热功能,以使乘员舱进行优先加热。通过所述方法及装置,平衡乘员舱和电池的加热需求,调整乘员舱加热和电池加热的能量分配,满足乘客的舒适性的同时确保电池温度能够处于合适的温度区间内,以保证车辆的动力性需求。
