Patent ID: 7898103

Claim:
A power supply apparatus for a vehicle, comprising: a first power storage device; a power supply line for feeding an inverter that drives a motor; a first voltage converter provided between said first power storage device and said power supply line for converting a voltage; a second power storage device; a second voltage converter provided between said second power storage device and said power supply line for converting a voltage; a connecting portion provided between said second power storage device and said second voltage converter for switching between an electrically connected state and a disconnected state; a capacitor coupled to a path connecting said connecting portion and said second voltage converter; and a control device controlling said first and second voltage converters and said connecting portion, upon receiving a startup instruction, said control device controlling said first voltage converter such that electric power is supplied from said first power storage device to said power supply line, and controlling said second voltage converter such that said capacitor is charged from said power supply line, and after charging of said capacitor is completed, said control device switching said connecting portion from said disconnected state to said connected state.
