The invention relates to the technical field of new energy vehicles, and discloses a hydrogen-electricity hybrid power system energy control method, which comprises the following steps of: acquiring the required power of a whole vehicle and the SOC (State of Charge) of a power battery; if the SOC of the power battery is fully discharged, the required power of the whole vehicle is covered by the output power of the fuel cell system, and the power battery is charged at the same time; otherwise, the output power of the power battery covers; when the SOC of the power battery rises to be fully charged, the required power of the whole vehicle is covered by the power output by the power battery and the fuel cell system in a mixed mode, and meanwhile the current moment is marked as the completion of the full-charge and full-discharge cycle; in the process that the hybrid output power covers the required power of the whole vehicle, the total throughput of the output power of the power battery is calculated; when the total throughput of the output power of the power battery is greater than the total throughput of the battery with the minimum influence, covering by the output power of the power battery, and judging whether the SOC of the power battery is fully discharged or not in real time; according to the invention, the electric quantity calibration and voltage balance of the power battery can be effectively improved.
本申请涉及新能源汽车技术领域,公开了一种氢电混合动力系统能量控制方法,包括获取整车需求功率以及动力电池的SOC;若动力电池的SOC为满放,则整车需求功率由燃料电池系统的输出功率覆盖,同时为动力电池充电;否则由动力电池的输出功率覆盖;当动力电池的SOC上升至满充,则整车需求功率由动力电池和燃料电池系统混合输出的功率覆盖,同时标记当下时刻为完成满充满放循环;在混合输出功率覆盖整车需求功率的过程中,计算动力电池的输出功率总吞吐量;当动力电池的输出功率总吞吐量大于影响最小的电池总吞吐量时,由动力电池的输出功率覆盖,并实时判断动力电池的SOC是否为满放;本申请可有效改善动力电池电量校准和电压均衡性。
