Abstract
A battery pack, a charger, and a charging system. The battery pack includes a rechargeable battery, and a protection circuit to control charging and discharging of the battery, wherein the protection circuit includes a micom to output an operating state signal representing an operating state of the micom and a malfunction transferring unit to transfer information on whether the battery is malfunctioning based on the operating state signal. Accordingly, when an error is detected by the protection circuit of the battery pack, charging is stopped, and thus the battery pack may be stably charged.
