The invention provides a power conversion method and device between power batteries. The method comprises the following steps: respectively acquiring first SOC information determined by a first power battery in a first SOC determination mode and second SOC information determined by a second power battery in a second SOC determination mode; based on the second SOC information, performing SOC conversion on the first SOC information to obtain SOC conversion information of the first power battery in the second SOC determination mode; based on the SOC conversion information and the second SOC information, determining an SOC association relationship between the first power battery and the second power battery in a second SOC determination mode; and converting the power value in the original power MAP of the first power battery by adopting the SOC association relationship to obtain a new power MAP. According to the method, the power conversion of the power battery of different SOC determination methods is realized, and the stable operation of the whole vehicle is ensured.

    本申请提供一种动力电池间的功率转换方法及装置。该方法中分别获取第一动力电池以第一SOC确定方式确定的第一SOC信息,以及第二动力电池以第二SOC确定方式确定的第二SOC信息;基于第二SOC信息,对第一SOC信息进行SOC转换,得到第二SOC确定方式下第一动力电池的SOC转换信息;基于SOC转换信息和第二SOC信息,确定第二SOC确定方式下第一动力电池和第二动力电池的SOC关联关系;采用SOC关联关系,对第一动力电池的原功率MAP中的功率数值进行转换,得到新功率MAP。该方法实现了不同SOC确定方法的动力电池的功率转换,确保了整车能够保持稳定的运行。
