The invention provides a thermal management control method and device based on battery fast charging and electronic equipment. The method comprises the steps of obtaining a current parameter set of a battery system; according to a pre-created charging MAP table, determining an optimal charging rate of the battery system at the starting point of the next charging stage and a target temperature corresponding to the optimal charging rate; determining an expected thermal management rate of the thermal management system for charging the battery system at the optimal charging rate and the target temperature at the starting point; before the current SOC of the battery system reaches the next charging stage, the thermal management system is controlled to operate based on the thermal management multiplying power obtained through interpolation of the current thermal management multiplying power and the expected thermal management multiplying power; and when the current SOC of the battery system reaches the next charging stage, controlling the thermal management system to operate based on the expected thermal management rate. Therefore, the charging capability of the battery system can be brought into full play, and the charging efficiency is improved.

    本申请提供一种基于电池快充的热管理控制方法、装置及电子设备。方法包括:获取电池系统的当前参数集;根据预先创建的充电MAP表,确定电池系统在下一充电阶段的起始点的最优充电倍率及与最优充电倍率对应的目标温度;确定热管理系统在起始点使电池系统以最优充电倍率和目标温度进行充电的期望热管理倍率;在电池系统的当前SOC到达下一充电阶段前,基于当前热管理倍率和期望热管理倍率插值得到的热管理倍率,控制热管理系统运行;在电池系统的当前SOC到达下一充电阶段时,基于期望热管理倍率,控制热管理系统运行。如此,有利于充分发挥电池系统的充电能力,提高充电效率。
