A charging apparatus includes: a connecting unit; a charging unit; a temperature detecting unit; and an operation inhibiting unit. The connecting unit is electrically connected to a power supply portion installed inside a vehicle. The charging unit supplies at least a part of electric power supplied from the power supply portion via the connecting unit to a battery thereby to charge the battery. The operation inhibiting unit inhibits operation of a battery circuit provided in the battery when an ambient temperature detected by the temperature detecting unit has reached a preassigned designated temperature.
