Abstract
An apparatus for providing electrical power for a hybrid vehicle includes an integrated starter-generator and an inverter connected to an electrical energy storage device such as a capacitor and a battery by first and second switches respectively. A control turns the switches on and off in accordance with selected modes of operation to provide power from the capacitor to the integrated starter-generator and the battery and to provide power from the integrated starter-generator to the capacitor and the battery.
Claims15
An apparatus for providing electrical power for a hybrid vehicle comprising:
- an integrated starter-generator;
- an inverter connected to said integrated starter-generator;
- a storage means for storing electrical energy;
- a first switch means connected between said inverter and said storage means;
- a battery means for storing electrical energy;
- a second switch means connected between said inverter and said battery means;
- and
- a control means connected to said first and second switch means for selectively turning each of said first and second switch means on and off.
An apparatus for providing electrical power for an integrated starter-generator in a hybrid vehicle comprising:
- a capacitor means for storing electrical energy at a first voltage;
- a first switch means connected to said capacitor means;
- a battery means for storing electrical energy at a second voltage lower than the first voltage;
- a second switch means connected to said battery means, said first and second switch means being connected at a junction;
- and
- a control means connected to said first and second switch means for selectively turning each of said first and second switch means on and off to provide electrical power at the junction.
