PROTECTIVE CIRCUIT AND CHARGING DEVICE
First Claim
Patent Images
1. A protective circuit comprising:
- 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.

Abstract
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.

4. A protective circuit comprising:
-
a smoothing circuit in which a pulse-like discharging output permitting signal is input in a normal discharging state and the pulse-like discharging output permitting signal is not input in an abnormal discharging state; and a discharging output control element that is controlled so as to permit or stop a discharging output from an electric storage device to a load, permits the discharging output by an output signal in which the discharging output permitting signal is smoothened by the smoothing circuit, and stops the discharging output when an abnormal discharging state is detected. - View Dependent Claims (5, 6)

7. A charging device comprising:
-
a power supply circuit that generates a charging power supply; a charging output control element that controls permitting or stopping of output of the charging power supply; a charging control portion that detects a charging state, outputs a pulse-like output permitting signal when a charging state is normal, and does not output the output permitting signal when a charging state is abnormal; and a control signal generating portion that is connected to the charging control portion and outputs a control signal from the output permitting signal to the charging output control element. - View Dependent Claims (8, 9, 10, 11, 12, 13)
