Abstract
A system and method for providing parallel power in a hybrid-electric vehicle. The system includes a compact motor coupled to the input shaft of the vehicle's transmission. Advantageously, the compact motor and the engine use the same drivetrain. Both the compact motor and the engine are able to apply power to the portion of the drivetrain from the transmission to the wheels. Since the motor is compact and does not require a separate drivetrain, the parallel power system can be installed in an otherwise conventional vehicle without packaging difficulties.
Claims3
A method of converting heavy duty internal-combustion engine vehicle into a heavy duty parallel hybrid-electric vehicle, the heavy duty internal-combustion engine vehicle having a GVW of at least 10,000 lbs. and including an internal combustion engine and a transmission, the method comprising the steps of:
- removing the transmission from the heavy duty internal-combustion engine vehicle;
- installing a compact, pan-type electric motor into the vehicle;
- coupling the compact, pan-type electric motor to the internal-combustion engine;
- installing the transmission into the vehicle so that the compact, pan-type electric motor is between the internal combustion engine and the transmission;
- and
- coupling the compact, pan-type motor to the transmission.
