The invention discloses a charging adjustment method and device, charging equipment, a power system and a storage medium, and belongs to the technical field of new energy. The method comprises the following steps: in a process of charging a to-be-charged battery, acquiring temperature distribution data of the surface of the to-be-charged battery, pressure distribution data of the surface of the to-be-charged battery and residual electric quantity of the to-be-charged battery; and judging the current state of the battery to be charged according to the temperature distribution data, the pressure distribution data, the residual electric quantity and a coupling relationship among parameters when the battery to be charged is subjected to thermal runaway or lithium precipitation. Under the condition that it is judged that the to-be-charged battery will have thermal runaway or a lithium precipitation phenomenon occurs according to the parameters of the multiple dimensions, the charging current is adjusted, and the adjusted charging current is obtained; and charging the to-be-charged battery according to the adjusted charging current. The accuracy of the judgment result is improved, and the safety of the charging process is improved while the charging rate is ensured.

    本申请公开了一种充电调整方法、装置、充电设备、动力系统及存储介质,属于新能源技术领域。所述方法包括:在对待充电电池进行充电的过程中,获取待充电电池的表面的温度分布数据、待充电电池的表面的压力分布数据以及待充电电池的剩余电量;根据温度分布数据、压力分布数据、剩余电量,以及待充电电池在发生热失控或出现析锂时参数之间的耦合关系,判断待充电电池的当前状态。在根据多个维度的参数判断出待充电电池会发生热失控或出现析锂现象的情况下,对充电电流进行调整,得到调整后的充电电流;根据调整后的充电电流对待充电电池进行充电。提高了判断结果的准确性,在保证充电速率的同时,提高了充电过程的安全性。
