The invention discloses an electric quantity balancing method and device for a hybrid electric vehicle, and the method comprises the steps: determining a first SOC threshold value and a second SOC threshold value under a normal driving condition, and enabling the first SOC threshold value to be higher than the second SOC threshold value; the method comprises the steps of identifying a vehicle working condition at a current moment; based on the first SOC threshold value, the second SOC threshold value and the vehicle working condition at the current moment, the adjusted first SOC threshold value and the adjusted second SOC threshold value are obtained. And obtaining the vehicle electric quantity at the current moment. And charging the vehicle based on the adjusted first SOC threshold value, the adjusted second SOC threshold value and the electric quantity of the vehicle at the current moment to increase the electric quantity of the vehicle. According to the method, the SOC threshold value is adaptively adjusted according to the vehicle working condition so as to adaptively adjust the electric quantity balance interval of the hybrid electric vehicle, and the electric quantity balance requirements of the vehicle under different working conditions are met.

    本申请公开了一种混合动力汽车电量平衡方法和装置,确定正常行驶工况下的第一SOC门限值和第二SOC门限值,其中,第一SOC门限值高于第二SOC门限值。该方法包括:识别当前时刻的车辆工况。基于第一SOC门限值、第二SOC门限值和当前时刻的车辆工况,获取调整后的第一SOC门限值和调整后的第二SOC门限值。获取当前时刻的车辆电量。基于调整后的第一SOC门限值、调整后的第二SOC门限值和当前时刻的车辆电量,对车辆进行充电,增加车辆电量。该方法根据车辆工况自适应调整SOC门限值以自适应调整混合动力汽车的电量平衡区间,满足了车辆在不同工况下的电量平衡需求。
