The invention provides a battery heating control method, device and system, a storage medium and a vehicle. The method comprises the steps of detecting the temperature of a battery of the vehicle; ifthe temperature of the battery is less than or equal to a first preset temperature, controlling a generator of the vehicle to supply power to a brake resistor to heat the battery with the heat generated when the brake resistor works; and if the temperature of the battery is greater than the first preset temperature, controlling the generator to supply power to the battery. When the temperature ofthe battery is lower than the first preset temperature, the braking energy is used for heating the battery so as to improve the charging capacity of the battery; and after the battery temperature is higher than the first preset temperature, the braking energy is used for supplying power to the battery, and the braking energy recycling effect is achieved. Through the method, the charging performance of the battery of the vehicle in a low-temperature environment can be improved, the braking energy recovery efficiency is improved, and the endurance mileage of the vehicle is prolonged.

本申请提供一种电池加热控制方法、设备、系统、存储介质和车辆，所述方法包括：检测车辆的电池的温度；若所述电池的温度小于等于第一预设温度，则控制所述车辆的发电机为制动电阻供电，以使所述制动电阻工作产生的热量为所述电池加热；若所述电池的温度大于第一预设温度，则控制所述发电机为所述电池供电。在电池温度低于第一预设温度时，将制动能量用于为电池加热，以提高电池的充电能力；在电池温度高于第一预设温度后，将制动能量用于为电池供电，达到制动能量回收的效果。通过此方法，可以提高车辆的电池在低温环境下的充电性能，提高制动能量回收效率，延长车辆续航里程。
