The invention provides a method for improving the low-temperature cruising ability, and the method comprises the steps: calculating the average output power of a battery in a preset time period based on the received heating request information of the battery in a driving process; wherein the heating request information comprises a driving heating closing threshold value; in response to the fact that the average output power of the battery is smaller than a preset power value and it is determined that the vehicle needs to be charged in the process of driving to the destination, the estimated temperature and the estimated SOC of the battery when the vehicle reaches the charging site are calculated; and if it is determined that the battery needs to be cooled in the charging process based on the pre-estimated temperature and the pre-estimated SOC, the driving heating closing threshold value of the battery is reduced. According to the method, the battery is pre-estimated and analyzed in the driving process, and the driving heating closing threshold value for reducing the battery is determined, so that the energy of the battery can be more used for power output of the battery, the cruising ability of the battery is improved, and the cruising ability of the vehicle is further improved.

    本申请提供一种提高低温续航能力的方法,包括:在行车过程中,基于接收到电池的加热请求信息,计算预设时段内电池平均输出功率;其中,所述加热请求信息中包括行车加热关闭阈值;响应于确定所述电池平均输出功率小于预设功率值,且确定车辆行驶至目的地的过程中需要充电,则计算车辆到达充电地点时电池的预估温度及预估SOC;基于所述预估温度及预估SOC确定电池在充电过程中需要降温,则降低电池的所述行车加热关闭阈值。本申请通过在行车过程中对电池进行预估分析,确定降低电池的行车加热关闭阈值,以使得电池的能量能够更多地用于电池的功率输出,提升电池的续航能力,进而提升车辆的续航能力。
