1. Field
The present invention relates to a charging apparatus for charging a battery for a vehicle.
2. Description of Related Art
Japanese Patent Laid-Open No. 2006-136122 discloses a technique in which switching elements that supply control voltages to armature coils of a dynamo are added to a rectifying circuit to control the control voltages, so as to increase or decrease output voltages of the dynamo. Upon execution of this control, switching elements which control phases of voltages to be supplied to armature coils for three phases of the dynamo are required, and correspondence between the switching elements and three phases to be controlled has to be specified. A correct connection between the switching element and corresponding armature coil is required not only at the time of manufacture of a vehicle but also at the time of re-assembly after the dynamo and rectifying circuit are disconnected upon maintenance of the vehicle. If the correct connection is not attained at the time of manufacture or re-assembly, a normal operation as a battery charging apparatus cannot be obtained.
For this reason, for example, an input terminal of the rectifying circuit and a corresponding output terminal of the dynamo are colored in the same color to clarify distinctions of the terminals in advance, so that each switching element is correctly connected to the corresponding armature coil. However, distinctions by coloring of the terminals increase cost of the dynamo and rectifying circuit accordingly.
