The invention relates to a charging control method, a controller and a vehicle, and the method comprises the steps: obtaining the battery temperature of a battery, controlling a first battery pack to supply power to a load and controlling a second battery pack to charge the first battery pack when the battery temperature is lower than a first threshold value, the first battery pack is composed of a first battery cell of a plurality of battery cells, and the second battery pack is composed of a second battery cell of a plurality of battery cells; the second battery pack is composed of the remaining second battery cells, and the low-temperature performance parameters of the first battery cells are superior to those of the second battery cells; under the low-temperature condition, the battery pack with the better low-temperature performance parameter is selected to preferentially supply power to the load, the battery pack with the poor low-temperature performance parameter is controlled to supply power to the battery pack with the better low-temperature performance parameter, and the battery temperature is gradually increased to the proper temperature in the battery discharging process. The battery can support high-power discharge and endurance discharge under the low-temperature condition, can normally supply power to the electric vehicle, and meets the endurance mileage requirement of the electric vehicle.

    本公开涉及一种充电控制方法、控制器及车辆,该方法包括:获取电池的电池温度,在电池温度低于第一阈值的情况下,控制第一电池包供电给负载,且控制第二电池包给第一电池包充电,第一电池包由多个电芯的第一电芯组成,第二电池包由余下的第二电芯组成,第一电芯的低温性能参数优于第二电芯的低温性能参数;在低温条件下,选择低温性能参数更优的电池包优先对负载进行供电,并控制低温性能参数差的电池包为低温性能参数更优的电池包供电,电池放电的过程使得电池温度逐步升高到合适的温度,使得电池在低温条件下既能支持大功率放电,也能支持续航放电,可以正常为电动汽车供电,满足电动汽车的续航里程要求。
