The invention provides a battery charging method and device, a medium and a product, and relates to the field of battery charging. Extracting charging characteristics according to the battery state information, and constructing a battery characteristic database; based on the battery characteristic database, analyzing a charging habit of a user; the charging habit of the user comprises a charging time period and an average charging time length corresponding to the charging time period; based on the battery characteristic database, analyzing the accumulated ampere-hour amount of the battery charged under different SOC charging segments; estimating the optimal charging current of the user according to the charging habit of the user and the accumulated ampere-hour amount of the battery charged under different SOC charging segments, and formulating an optimal charging current strategy; and charging according to the optimal charging current strategy in idle time when the battery is fully charged but is not pulled out, and limiting the charging current. The battery can be effectively protected, and the service life of the battery is prolonged.

    本发明提供了一种电池充电方法、设备、介质及产品,涉及电池充电领域,方法包括:获取电池状态信息;根据所述电池状态信息,提取充电特征,构建电池特征数据库;基于所述电池特征数据库,分析用户充电习惯;所述用户充电习惯包括充电时段以及充电时段对应的平均充电时长;基于所述电池特征数据库,分析电池在不同SOC充电片段下充入的累计安时量;根据所述用户充电习惯以及电池在不同SOC充电片段下充入的累计安时量估算用户本次最优充电电流,制定最优充电电流策略;在电池充电满电后但未拔出的闲置时间,按照所述最优充电电流策略进行充电,对充电电流进行限制处理。本发明能够有效保护电池,延长电池使用寿命。
