Abstract:
1. A vehicle comprising: a power storage device; an electric power reception unit receiving electric power from an electric power transmission unit external to a vehicle; a first rotating electric machine driven by electric power supplied from said power storage device and electric power supplied from said electric power reception unit; and a control device for performing drive control of said first rotating electric machine, said control device calculating first electric power that can be output from said power storage device based on a state of said power storage device, calculating second electric power that can be charged from outside based on transmittable electric power of said electric power transmission unit and chargeable electric power of said electric power reception unit, obtaining a sum of said first electric power and said second electric power as electric power suppliable from a power supply, and performing drive control of said first rotating electric machine based on said electric power suppliable from a power supply; a voltage conversion unit converting a first voltage output from said power storage device; and a rotating electric machine driving unit receiving a voltage converted by said voltage conversion unit to drive said first rotating electric machine, wherein said electric power reception unit is connected to an electric power transfer path connecting between said voltage conversion unit and said rotating electric machine driving unit, and said control device performs voltage conversion control for said voltage conversion unit based on a highest voltage among said first voltage output from said power storage device, a second voltage requested by said rotating electric machine driving unit and a third voltage requested by said electric power reception unit; and an internal combustion engine; a second rotating electric machine receiving power from said internal combustion engine to generate electric power used in said first rotating electric machine; a voltage conversion unit converting a first voltage output from said power storage device; and a rotating electric machine driving unit receiving a voltage converted by said voltage conversion unit to drive said first and second rotating electric machines, wherein said rotating electric machine driving unit requests a second voltage determined based on an operation of each of said first and second rotating electric machines, said electric power reception unit is connected to a neutral point of a stator coil of said second rotating electric machine and a neutral point of a stator coil of said first rotating electric machine, and said control device performs voltage conversion control for said voltage conversion unit based on a highest voltage among said first voltage output from said power storage device and said second voltage requested by said rotating electric machine driving unit, and on a third voltage requested by said electric power reception unit.
