Document Type and Number:
Japanese Patent JP2014087156
Kind Code:
A
Abstract:

To shorten a time until a vehicle becomes a Ready-On state by improving fault detection efficiency of a relay device.

ECU 30 operates a system main relay SMR2 to connect a second energy storage device BAT2 with a second capacitor C2 and carries out fault detection of the system main relay SMR2 based on voltage of the second capacitor C2. After the fault detection of the system main relay SMR2, ECU 30 operates a system main relay SMR1 to connect a first energy storage device BAT1 with a first capacitor C1 and carries out fault detection of the system main relay SMR1 based on voltage of the second capacitor C1.
