Abstract
A vehicle electric power supply device includes an electric power storage device, a relay device, an electric current sensor, and a control device. The control device instructs an external electric power supply to stop outputting supplied electric power when an abnormality in the electric current value is detected during charging of the electric power storage device. The control device also controls a timing of cutting off a switch of the relay device, based on a state of the electric current value and a state of an amount of electric power charged to the electric power storage device, after the instruction to stop output.
