Abstract: In a control method for a zinc battery, when the zinc battery is charged, the charging is terminated when a charging current falls below a first threshold value. Then, even when the charging current does not fall below the first threshold value, the charging is terminated when a charge amount of the zinc battery exceeds a second threshold value. A power supply system comprises a zinc battery and a control unit controlling charging and discharging of the zinc battery. The control unit terminates the charging when a charging current falls below a first threshold value. The control unit terminates the charging when a charge amount of the zinc battery exceeds a second threshold value even when the charging current does not fall below the first threshold value.
