Title:
電源装置、及びその制御方法
Document Type and Number:
Japanese Patent JP4510753
Kind Code:
B2
Abstract:
A power supply device and a method for controlling the power supply device in which a fusion checking process for the cathode side relay and the anode side relay is easily performed within a short period of time. A battery ECU (controller) measures a first voltage between a high potential output terminal and an anode terminal of the rechargeable battery when a cathode side relay arranged between the high potential output terminal and a cathode terminal of the rechargeable battery and an anode side relay arranged between a low potential output terminal and the anode terminal of the rechargeable battery are open to determine whether or not a cathode side relay is fused. The battery ECU also measures a second voltage between the low potential output terminal and the cathode terminal of the rechargeable battery to determine whether or not the anode side relay is fused.
