Abstract
A drive train for a vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device by an electrical power transmission system, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In all modes of operation where the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.
Claims20
A drive train for a vehicle, the drive train comprising:
- a first electromagnetic device;
- a second electromagnetic device electrically coupled to the first electromagnetic device by an electrical power transmission system;
- and
- an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy,
- wherein, in all modes of operation where the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.
A vehicle comprising:
- a first motor/generator;
- a second motor/generator electrically coupled to the first motor/generator by an electrical power transmission system;
- and
- an engine coupled to the first motor/generator and configured to drive the first motor/generator to provide electrical energy,
- wherein, in all modes of operation where the engine drives the first motor/generator to provide the electrical energy, the first motor/generator operates without being electrically coupled to an energy storage device that is configured to be charged by the electrical energy from the first motor/generator.
A method of operating a vehicle, the method comprising:
- driving, by an engine, a first electromagnetic device to generate electrical energy, the first electromagnetic device being electrically coupled to a second electromagnetic device;
- consuming, by the second electromagnetic device, at least a portion of the electrical energy generated by the first electromagnetic device while the first electromagnetic device is driven by the engine;
- and
- driving, by the second electromagnetic device, a drive axle to propel the vehicle,
- wherein the electrical energy generated by the first electromagnetic device while the first electromagnetic device is driven by the engine is never provided to an energy storage device.
