(57) Abstract :
An ECU (60) determines based on a voltage (V) from an insulation resistance decrease detector (50) whether the insulation resistance
of a power supply device (100) decreases or not. When a load (80) external to the vehicle is not connected to the power supply device
(100), the ECU (60) sets a determination threshold value for determining that the insulation resistance decreases to a normal first
value. On the other hand, when the load (80) external to the vehicle is electrically connected to the power supply device (100), the
ECU (60) sets the determination threshold value to a second value which is lower than the first value, in consideration of an increase
in the capacitive component due to a capacitor (C3, C4) of a Y-capacitor (84).
