Power supply system for vehicle
First Claim
1. A power supply system for a vehicle comprising:
- a power storage device;
an input port that receives electric power supplied from a source external to the vehicle;
first and second rotating electrical machines that function as rotating electrical machines driven by electric power supplied from the power storage device when the vehicle is running;
a first charger that is operably configured to receive the electric power supplied from the source external to the vehicle and thereby charge the power storage device;
a second charger that is operably configured to receive the electric power supplied from the source external to the vehicle and thereby charge the power storage device; and
a control device that selects either the first or the second charger to be used for converting the electric power supplied from the source external to the vehicle into charging electric power, whereinthe first charger includes the first and second rotating electrical machines, andthe control device selects either the first or the second charger based on a voltage detected at the input port.

Abstract
A power supply system for a vehicle includes: batteries; motor generators operating as rotating electrical machines driven by electric power in the batteries when the vehicle is running, and constituting a first charger when the batteries are charged by electric power received from a source external to the vehicle and; an inlet receiving the electric power supplied from the external source; a second charger receiving the electric power supplied from the external source and charging the batteries; and a control device selecting one of the first and second chargers and performing control for converting the electric power supplied from the external source to the inlet into charging electric power using the selected charger. Thus, a power supply system for a vehicle that is chargeable from various power supplies at the time of charging and has reduced charge loss can be provided.
