The invention provides a parallel control method and device of battery clusters and a storage medium, the method obtains control operation and parameter information of each battery cluster by responding to a parallel control instruction, and the parameter information comprises a first electric quantity value and a first voltage value of each battery cluster. The magnitude of the circulating current is mainly influenced by the inter-cluster voltage difference of the battery clusters. Therefore, in the charging and discharging stage, the target cluster is selected from the battery clusters according to the to-be-executed control operation and the first electric quantity value of each battery cluster, and then the to-be-processed cluster used for parallel connection is determined according to the first voltage value of the target cluster. Therefore, the selected to-be-processed cluster can generate less circulating current at the cluster merging moment so as to protect components of a power loop in the cluster, and an additional control circuit does not need to be introduced in the process, so that the cost can be effectively reduced.

    本申请提供了一种电池簇的并联控制方法、装置和存储介质,该方法通过响应于并联控制指示以获取控制操作和各电池簇的参数信息,该参数信息中包括每个电池簇的第一电量值和第一电压值。由于环流的大小主要受电池簇的簇间压差影响。因此在充放电阶段,进而根据待执行的控制操作和各电池簇的第一电量值从各电池簇中选定目标簇,继而根据目标簇的第一电压值确定用于并联的待处理簇。由此选出的待处理簇在并簇瞬间会产生较少的环流进而保护簇内动力回路的元器件,并且上述流程无需引入额外的控制电路,可有效降低成本。
