The invention relates to a management method for a power battery of a vehicle, and the management method at least comprises the following steps: obtaining data of a plurality of state parameters of each single battery of the power battery; generating a battery diffusion index according to the data in combination with a machine learning algorithm model, wherein the battery diffusion index is used for analyzing the battery diffusion risk of the power battery; and when determining that a battery diffusion problem exists based on the battery diffusion index, implementing a corresponding balance control measure. The disclosure also relates to a corresponding computer program product and a battery management system for a vehicle. Therefore, the health condition of the power battery can be accurately evaluated, the battery diffusion phenomenon can be timely predicted, the performance degradation of the power battery can be reliably avoided, and the service life of the power battery can be prolonged.

    本公开涉及一种用于车辆的动力电池的管理方法,其中,所述管理方法至少包括以下步骤:获取所述动力电池的各个电池单体的多个状态参数的数据;根据所述数据结合机器学习算法模型生成电池扩散指数,所述电池扩散指数用于分析所述动力电池的电池扩散风险;当基于所述电池扩散指数确定存在电池扩散问题时,实施相应的均衡控制措施。本公开还涉及一种相应的计算机程序产品和用于车辆的电池管理系统。能够准确地评估动力电池的健康状况,及时预测电池扩散现象的出现,由此可靠地避免动力电池的性能衰减、延长动力电池的使用寿命。
