The invention discloses an operation energy balance control method and assembly for an energy storage unit of a hybrid power vehicle, and aims to solve the problem that in the prior art, control strategies for each operation are different due to different SOC values before and after vehicle operation. By adopting the technical scheme, according to the load power requirement of the vehicle and the SOC value of the energy storage unit, the power is distributed to the power generation unit and the energy storage unit according to the pre-distribution principle, the corresponding relation between the termination SOC value and the initial SOC value after the vehicle runs after distribution according to the principle is calculated, whether SOC balance control needs to be carried out or not is determined according to the corresponding relation, and the SOC balance control efficiency is improved. If yes, the output power of the power generation unit and the energy storage unit is adjusted according to the corresponding relation, so that the termination SOC value is equal to the initial SOC value. According to the scheme, the SOC of the energy storage unit is controlled to be equal before and after the vehicle runs, so that the vehicle driving operation and the transient energy control strategy are the same, the operation difficulty of a driver is reduced, optimal energy control is conveniently realized, and the utilization efficiency of energy is improved.

    本申请公开了一种混合动力车辆储能单元运营能量平衡控制方法及组件,相对于当前技术中,由于车辆运行前后的SOC值不同导致每次运营的控制策略不同。采用本技术方案,根据车辆的负载功率需求以及储能单元的SOC值,按预分配原则给发电单元和储能单元分配功率,并计算按此原则分配后,车辆运行后的终止SOC与初始SOC值的对应关系,根据对应关系确认是否需要进行SOC平衡控制,若需要则根据对应关系调整发电单元和储能单元的输出功率,使终止SOC值与初始SOC值相等。本方案控制车辆运行前后储能单元的SOC相等,使车辆驾驶操作和瞬态能量控制策略相同,降低了司机的操作难度,也便于实现最优能量控制提高能源的利用效率。
