A charging device is provided. The charging device switches to a (n+1)-th charging rate from a n-th charging rate when constant current charging is performed on a secondary battery at the n-th charging rate, at an SOC smaller than an SOC at which a voltage local minimum value appears when an experimental battery is charged at the n-th charging rate. The (n+1)-th charging rate is lower than the n-th charging rate, and n is a natural number.
Charging device, charging method, secondary battery, battery pack, electric vehicle, power storage device, electronic device, and power storage system using SOC
