The invention discloses a hybrid electric vehicle battery target SOC management method, a medium and a vehicle, and belongs to the technical field of hybrid electric vehicles, and the hybrid electric vehicle battery target SOC management method comprises the steps that navigation state data are acquired, and whether a starting mode is adopted or not is judged according to the navigation state; if yes, determining a driving mode, a corresponding driving mode design power demand and a corresponding driving mode compensation power according to the navigation state data; determining the optimal power of the corresponding driving mode according to the design power demand of the corresponding driving mode and the compensation power of the corresponding driving mode, and determining the optimal SOC of a power battery of the corresponding driving mode according to the optimal power of the corresponding driving mode; and performing dynamic closed-loop control according to the optimal SOC of the power battery in the corresponding driving mode and a closed-loop adjustment interval obtained through calibration. The method can adapt to battery capacity change conditions in different driving states, and more accurate control and management are realized. The charging/discharging of the battery can be accurately controlled, so that the energy utilization efficiency of the battery is improved.

    本发明公开了一种混合动力汽车电池目标SOC管理方法、介质及车辆,属于混合动力汽车技术领域,包括:获取导航状态数据,根据所述导航状态判断是否为开启模式;若是,则根据所述导航状态数据确定驾驶模式、相应驾驶模式设计功率需求和相应驾驶模式补偿功率;根据所述相应驾驶模式设计功率需求和相应驾驶模式补偿功率确定相应驾驶模式最佳功率,根据所述相应驾驶模式最佳功率确定相应驾驶模式动力电池最佳SOC;根据所述相应驾驶模式动力电池最佳SOC和通过标定获取的闭环调整区间进行动态闭环控制。本发明能够适应不同的行驶状态下的电池容量变化情况,实现更加精准的控制和管理。能够准确地控制电池的充/放电,从而提高电池的能量利用效率。
