Abstract:
A vehicle includes a PCU controlling electric power supplied to a motor, a first power storage device, a second power storage device, an ECU, a charger, system main relays SMR1 to SMR4, SMRA, SMRB, and charging relays CR1 to CR4. The first power storage device is formed such that a first module and a second module which are separately disposed are connected in series through SMRA and SMRB. The first power storage device is connected to the PCU through SMR1 and SMR2. The second power storage device is connected to the PCU through SMR3 and SMR4. The charger has a capacitor that is connected to the first power storage device through CR1 and CR2 and also connected to the second power storage device through CR3 and CR4. When charging is completed, the ECU turns on CR1, CR2, SMR1, and SMR2, and turns off SMRA, SMRB, CR3, CR4, SMR3, and SMR4.
