Abstract: A vehicular power source device includes a first generator that generates electric power by rotating a rotor, a second generator that rotates at a higher rotation speed than an upper limit of a rotation speed of the first generator to generate electric power, a detector that detects the rotation speed of the first generator, and a controller that controls power generation of the first and second generators. The controller causes the first generator to generate electric power when the rotation speed of the first generator detected by the detector is not larger than the upper limit of the rotation speed of the first generator, and causes only the second generator to generate electric power when the rotation speed of the first generator detected by the detector is larger than the upper limit of the rotation speed of the first generator.
