A control device for a solid-state battery has a processor that controls charging of the solid-state battery by referring to a map which is defined in advance based on an SOC of the solid-state battery and indicates a range in which continuous charging of the solid-state battery is allowed. The processor charges the solid-state battery until the SOC reaches an SOC threshold acquired by referring to the map based on the SOC at the start of charging. When the SOC reaches the SOC threshold, the processor suspends the charging of the solid-state battery during a suspension time acquired by referring to the map based on the SOC threshold. When the suspension time has elapsed, the processor resumes the charging to charge the solid-state battery until the SOC reaches an SOC threshold acquired by referring to the map based on the SOC at the resumption of charging.
