The invention relates to the technical field of vehicle-mounted power supply control, and particularly discloses a vehicle energy balance control method and device, a hybrid electric vehicle and a storage medium. The vehicle energy balance control method comprises the following steps: acquiring actual accumulative mileage of each time point of vehicle operation and standard accumulative mileage corresponding to each time point; when the difference value between the actual accumulative mileage and the standard accumulative mileage is smaller than a preset mileage, the actual output energy of the battery management system is obtained; and correcting the actual output energy of the battery management system to ensure the energy balance of the vehicle. According to the method, by calculating the charging and discharging conditions of the battery, the expected difference of the energy change is used as a compensation item to correct the energy change, and the energy balance of the complete driving cycle is ensured. And the energy balance consistency problem caused by external reasons such as objective driving factors, hardware aging and efficiency fluctuation under fixed-point power generation control is reduced.

    本发明涉及车载电源控制技术领域,具体公开了一种车辆能量平衡控制方法、装置、混动车及存储介质。所述车辆能量平衡控制方法包括:获取车辆运行各时间点的实际累计里程以及各时间点对应的标准累计里程;在所述实际累计里程与所述标准累计里程的差值小于预定里程时,获取电池管理系统的实际输出能量;对所述电池管理系统的实际输出能量进行修正以保证车辆的能量平衡。该方法通过计算电池充放电状况,将能量变化的预期差距作为补偿项进行能量变化的修正,保证完整的驾驶循环的能量平衡。减少对于定点发电控制下由于客观驾驶因素、硬件老化、效率波动等外界原因引起的能量平衡一致性问题。
