Power battery remaining use value quantification and prediction method and system

The invention provides a power battery residual use value quantification and prediction method and system. The scheme comprises the following steps: acquiring the battery health state, residual service life and capacity fading rate index data of each single battery; on the basis of the index data, carrying out weight calculation on each index by utilizing an entropy weight method; determining an initial score of the single battery based on the maximum value and the minimum value of each index data and each index weight; based on the initial score, the use value proportion of the battery performance parameter influence and the battery raw material cost proportion, determining the percentage of the residual use value of the single battery; and obtaining a residual value prediction result of each single battery based on the percentage of the residual use value of the single battery and the price of the single battery. 本发明提供了一种动力电池剩余使用价值量化与预测方法及系统，所述方案包括获取各单体电池的电池健康状态、剩余使用寿命以及容量衰减率指标数据；基于所述指标数据，利用熵权法对每个指标进行权值计算；基
