Claims

[Scope of utility model registration request]

In a vehicle charging device that controls the output voltage of an alternator with an excitation current and rectifies the output voltage to charge the battery, a Zener diode that detects the battery voltage;
It has an auxiliary transistor that turns on and off as the Zener diode turns on and off, a time constant circuit inserted between the input terminal and the output terminal of the auxiliary transistor, and a transistor that switches an excitation current. A vehicle charging device characterized by having a hysteresis characteristic in turning on and off an excitation current.
