摘要：
A protective circuit includes a smoothing circuit in which a pulse-like charging output permitting signal is input in a normal charging state and the pulse-like charging output permitting signal is not input in an abnormal charging state, and a charging output control element that is controlled so as to permit or stop a charging output with respect to an electric storage device, permits the charging output by an output signal in which the charging output permitting signal is smoothened by the smoothing circuit, and stops the charging output when an abnormal charging state is detected.
