POWER SUPPLY SYSTEM OF VEHICLE AND VEHICLE INCLUDING SAME

摘要

A power supply system of a vehicle includes: a first power storage device that stores power for travel; a second power storage device that stores power for auxiliary equipment; a voltage conversion device that is provided between the first power storage device and the second power storage device, and that charges the second power storage device through voltage conversion of power that is outputted by the first power storage device; and a control device that executes charging control of charging the second power storage device by way of the voltage conversion device, while the vehicle is parked. The control device determines an abnormality in the second power storage device on the basis of information relating to dark current in the second power storage device during parking, and, upon determination of abnormality in the second power storage device, sets the charging control to non-execution.
