POWER SOURCE CONTROL DEVICE, AND RELAY MALFUNCTION DETECTING METHOD |
| 摘要 |
When an ignition key is turned ON, an ECU (50) drives a bidirectional DC/DC converter (40) to charge a capacitor (C1) to a voltage Vth1 (<VB). The ECU (50) turns on a first relay (SMR1) only and diagnoses whether or not a second relay (SMR2), which is off, is welded, based on a change in a voltage VL at that time. After the diagnosis on welding, the ECU (50) turns on the second relay (SMR2), and the capacitor (C1) is charged to a voltage level of a main power storage device (B). |
