The invention relates to a power battery SOC calibration method, a power battery SOC calibration device, power battery SOC calibration equipment and a readable storage medium, and relates to the technical field of hybrid power commercial vehicle whole vehicles. The real-time accumulated throughput electric quantity of the power battery, the real-time accumulated travelled distance of the vehicle and the real-time accumulated running duration of the vehicle are obtained; determining whether SOC initial value calibration needs to be carried out or not based on the real-time accumulated throughput electric quantity, the real-time accumulated travelled distance and the real-time accumulated operation duration; if it is determined that the SOC initial value needs to be calibrated, the engine and the driving motor are controlled to fully charge the power battery so that the SOC initial value can be calibrated to be 100%, and if it is determined that the SOC initial value does not need to be calibrated, the step of obtaining the real-time accumulative throughput electric quantity of the power battery, the real-time accumulative travelled distance of the vehicle and the real-time accumulative running duration of the vehicle is executed again. According to the invention, automatic calibration of the SOC initial value of the power type power battery of the hybrid commercial vehicle can be effectively realized, so that the error of SOC estimation is reduced.
本申请涉及一种动力电池SOC校准方法、装置、设备及可读存储介质,涉及混合动力商用车整车技术领域,包括当动力电池完成上一周期的SOC初始值校准后,获取动力电池的实时累计吞吐电量、车辆的实时累计行驶里程以及车辆的实时累计运行时长;基于实时累计吞吐电量、实时累计行驶里程和实时累计运行时长确定是否需要进行SOC初始值校准;若确定需要,则控制发动机和驱动电机对动力电池进行满充,以校准SOC初始值为100%,若确定不需要,则重新执行获取动力电池的实时累计吞吐电量、车辆的实时累计行驶里程以及车辆的实时累计运行时长的步骤。本申请可有效实现混动商用车功率型动力电池的SOC初始值的自动校准,进而降低SOC估算的误差。
