Patent attributes
Provided is an in-vehicle power supply device that ensures safety and meets the standards required by the regulation associated with a high voltage, without requiring a large change in the in-vehicle power supply device when outputting DC electric energy stored in a storage battery mounted on a vehicle to the outside of the vehicle, and also provided is a photovoltaic power generation device. In the in-vehicle power supply device, when controlling a switching unit (112) so that a second DC voltage output from a DC/DC converter (111) is output to a DC voltage outlet (103), a vehicle-side control unit (107) controls the DC/DC converter (111) so that the second DC voltage becomes smaller than or equal to a predetermined voltage value that is smaller than the rated voltage value of a storage battery (106).
