1. A storage battery control device configured to control a storage battery system, the storage battery system comprising a plurality of storage batteries connected in series and a bypass circuit configured to selectively bypass each of the plurality of storage batteries, the storage battery control device comprising:
a processor; and
a memory having instructions that, when executed by the processor, cause the storage battery control device to perform operations comprising:
performing a first process of causing the bypass circuit to preferentially bypass, among the plurality of storage batteries, a storage battery having a smaller remaining charge amount until completion of charging than those of the other storage batteries, and charging at least one of the plurality of storage batteries such that a difference in remaining charge amounts of the plurality of storage batteries until completion of charging is reduced; and
performing, after the first process, a second process of charging the plurality of storage batteries until the charging is completed.
