A current detection apparatus for detecting a current from a battery flowing through a harness. The apparatus includes a resistor having a current carrying member disposed between a terminal of the battery and the harness, a circuit board provided thereon with a current detection circuit for detecting a current flowing through the resistor, and a casing having a recessed portion for accommodating the circuit board, a cover for closing an opening of the recessed portion. The circuit board includes a solder junction between the circuit board and a terminal protruding from an inside bottom of the recessed portion and passing through a through hole arranged on the circuit board, and an open end of the recessed portion that can be engaged with the cover is non-parallel to the circuit board so that at least a portion of the circuit board including the solder junction lies outside of the recessed portion.

Current detection apparatus

The vehicle-use power generation control apparatus includes a first section to control an excitation current of a vehicle generator driven by a vehicle engine such that a power generation voltage of the vehicle generator is kept at a first set value, a second section to perform gradual excitation control in order to gradually increase the excitation current, a third section configured to inhibit the gradual excitation control when the power generation voltage falls below a second set value lower than the first set value while the gradual excitation control is performed, a fourth section to detect a rotational speed of the vehicle engine or the vehicle generator, a fifth section to determine a limit value of the excitation current based on the detected rotational speed, and a sixth section configured to limit the excitation current below the limit value when the power generation voltage falls below the second set value.

Vehicle-use power generation control apparatus and vehicle-use power generation control system

The vehicle-use power generation control device includes a first function of detecting a temperature around a generator mounted on a vehicle, a second function of setting a target control voltage in accordance with the temperature detected by the first function, and a third function of controlling an output voltage of the generator at the target control voltage set by the second function. The second function is configured to determine the target control voltage on the basis of a target power generation voltage defining the target control voltage to be set at a predetermined temperature, and a predetermined gradient of the target control voltage with respect to the temperature detected by the first function.
