- EV traveling control is executed in a state where the first slave power source is connected to second converter 12-2 (S102) ( S108). Therefore, until the time t1 when SOCs1 falls to the threshold value, EV running control is performed with the power of the master power supply and the first slave power supply.

- the system voltage Vh during the HV running control becomes the lower limit value Vlow (HV) without performing the boosting operation by the first converter 12-1. Therefore, power loss due to boosting can be reduced. Furthermore, it is possible to reduce power consumption by suppressing the system voltage Vh from becoming unnecessarily high as compared to the case where the necessary total number N of cells is evenly distributed among the power sources.
- forced HV traveling control is executed (S112).
- the connection state with each power source is maintained at the time when the HV switch 17 is turned on (when the HV request signal Rhv is received). Therefore, it is possible to run while maintaining the SOC of the main power supply and the slave power supply within a predetermined range.
- Such traveling is effective when the driver wants to maintain the power for some reason, for example, when the power of each power source is required after arrival at the destination.
- the control device only the master power source is connected to the MG at the time of HV traveling control, and the output voltage of the master power source among the necessary number of cells is the voltage at the time of HV traveling control.
- the number of battery cells to be the lower limit value of the control range is distributed to the master power source, and the remaining number of battery cells is evenly distributed to the remaining slave power sources.
- the present invention can also be applied to a hybrid vehicle including three or more slave power supplies.
