Claims

[Scope of utility model registration request]

(1) The power generated by the alternator is controlled by the field current,
A vehicle charging device that rectifies the output voltage to charge a battery includes a power detection circuit that detects the generated power of the alternator, the input power of the battery, and the load power consumption, and the accumulation of the sum of the respective powers over a long period of time. A vehicle charging device comprising: a power calculation circuit that calculates a value such that the value becomes 0; and an If control signal output circuit that controls on/off of a field current based on the calculation result of the calculation circuit. ,Device.

(2) The power calculation circuit supplies the load power consumption during acceleration and constant speed from the battery, and replenishes the battery output power during deceleration to reduce the cumulative value of the long-term sum of each power to 0. 1. A vehicle charging device according to claim 1, which is configured to perform such control.

(3) The If control signal output circuit is configured to control power generation by flowing a field current regardless of the output of the power calculation circuit when the battery voltage is abnormally low. The vehicle charging device described in Section 1.
