The invention relates to the technical field of electric vehicles, in particular to a battery life prediction method and device, a server and a storage medium, and the method comprises the steps: obtaining vehicle data reaching a battery life attenuation node; identifying basic attribute information of a vehicle in the vehicle data and internal and external information of a battery using process, establishing a first index data set according to the basic attribute information, and establishing a second index data set according to the internal and external information of the battery using process; weight assignment is carried out on indexes in the second index data set according to the time stage, a first prediction model is trained in combination with the number of battery cycles corresponding to the battery life attenuation node, the first index data set and the first prediction model are associated after training is completed, and the battery life of the vehicle is predicted through the first prediction model. Therefore, the problem that the accuracy of a prediction result is poor due to the fact that internal and external information in the battery using process is not fully considered when the service life of the battery is predicted in related technologies is solved.

    本申请涉及电动汽车技术领域,特别涉及一种电池寿命预测方法、装置、服务器及存储介质,其中,方法包括:获取已经达到电池寿命衰减节点的车辆数据;识别车辆数据中车辆的基础属性信息和电池使用过程内外信息,根据基础属性信息建立第一指标数据集,根据电池使用过程内外信息建立第二指标数据集;按照时间阶段对第二指标数据集中指标进行权重赋值,并结合电池寿命衰减节点对应的电池循环次数训练第一预测模型,在训练完成后关联第一指标数据集与第一预测模型,利用第一预测模型预测车辆的电池寿命。由此,解决了相关技术中在预测电池寿命时,没有充分考虑电池使用过程内外信息,导致预测结果准确性较差等问题。
