A voltage increase due to a charging current from a driving motor is limited to prevent battery deterioration resulting from the voltage increase, and sufficient safety is ensured. A battery pack includes a rechargeable battery (1), a charge FET (3) including a parallel diode (7) connected in series with the battery (1), and a control circuit (7) configured to control turning on and off of the charge FET (3). The control circuit (7) includes a discriminating circuit (5) configured to detect a bicycle-mounted state and a charger-connected state, and a memory (6) configured to store a full charge voltage of the battery (1). The control circuit (7) is configured to, while the discriminating circuit detects the bicycle-mounted state, turn off the charge FET (3). The control circuit (7) is configured to, while the discriminating circuit detects the charger-connected state, stop charging the battery (1) by switching the charge FET (3) to turn off the charge FET (3) upon detecting that a voltage of the battery (1) charged by a charger becomes higher than the full charge voltage.
