The invention provides a power battery system discharge power correction control method and system, and the method comprises the steps: enabling a minimum power battery monomer voltage to trigger a threshold value under the conditions that the working environment/working condition of a power battery is more complex or the performance of the battery is changed, and the actual discharge power is corrected through controlling the voltage and the current at the same time, and the actual discharge power is corrected while the trigger voltage threshold is ensured. The technical problems that the over-current risk is high, an under-voltage fault is likely to happen, and the actual power and the decreasing amplitude of the minimum voltage of the single body are not synchronous are solved.

    本发明提供动力电池系统放电功率修正控制方法及系统,方法包括:力电池的工作环境/工况更为复杂或电池性能发生一些变化,存在P实际远小于P允许的情况下,最小动力电池单体电压触发阈值,通过同时控制电压、电流,修正实际的放电功率,确保触发电压阈值的同时,修正实际放电功率。本发明解决了过流风险高、易发生欠电故障以及实际功率与单体最小电压的降幅不同步的技术问题。
