Abstract: A charging system includes a charger for a storage battery including a lithium-ion battery, and a battery-side device that monitors a battery state including a lithium precipitation amount in the lithium-ion battery. The charger includes an information acquisition unit that acquires battery information including the battery state from the battery-side device, a charging determination unit that determines whether charging of the storage battery is possible based on the battery information, and a charging control unit that charges the storage battery based on a determination result of the charging determination unit.

Abstract: The battery evaluation system is a system for evaluating a storage battery including a lithium-ion battery. The battery evaluation system includes a battery monitoring unit that monitors a battery state of the storage battery, and an evaluation device that acquires battery state information including a monitoring result of the battery state from the battery monitoring unit and evaluates the storage battery based on the battery state information. The battery monitoring unit calculates a lithium precipitation amount in the lithium-ion battery as one index indicating the battery state. The evaluation device determines safety of the storage battery based on the lithium precipitation amount.
