A power supply system includes a first drive motor, a second drive motor, a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter that converts a voltage between the first power line and the second power line, and an ECU that operates the first and second inverters and the voltage converter and controls charging and discharging of the first and second batteries. In a case where total required power is larger than first outputtable power of the first battery, the ECU discharges a shortage of power from the second battery to the second power line, wherein the shortage of power is obtained by excluding an amount that is output by the first battery from the total required power.

In a power source system, a high-voltage battery and a low voltage battery are configured to store electric powers to be supplied to a traveling motor and an accessory, respectively. A step-up unit is interposed between the low-voltage battery and the traveling motor, and is configured to step up a voltage of the low-voltage battery and apply the stepped-up voltage to the traveling motor. A controller is configured to perform switching to a normal-time electric power supply circuit, in which the high-voltage battery and the traveling motor are coupled to each other, when the high-voltage battery is in a normal state and perform switching to an abnormal-time electric power supply circuit, in which the low-voltage battery and the traveling motor are coupled to each other via the step-up unit, when the high-voltage battery is in an abnormal state.

A system and method for integrated charging a vehicle includes a hybrid excitation machine, operable as a traction motor and including a rotor separated by an air gap from a stator with AC windings. An AC utility line power supply is connected to the AC windings providing an electrical current to the vehicle and inducing a magnetic flux across the air gap and in the rotor. A short circuit, an open circuit, or a DC voltage may be applied to a DC winding in the stator to reduce the magnetic flux into the rotor. A field coil in the rotor may be excited with a DC voltage using a secondary coil on the rotor in a traction mode. The secondary coil is excited by the stator windings using field-oriented control in a “self-excited machine” embodiment, and is directly excited by a separate primary coil in an “externally-excited machine” embodiment.
