Embodiment Construction

[0085] Referring to Figure 1, a preferred embodiment of the apparatus is disclosed. The invention comprises an engine 1 connected to a transmission 4 . The engine 1 can be connected via a clutch or via a fixed gear or shafting. The first electric motor / generator 2 is connected to a shaft on the engine 1 or on the transmission 4 side of the engine / transmission interface. The transmission 4 transmits power from the engine 1 and the first motor / generator 2 through the transmission 4 to the drive shaft 15 , the differential 9 , and then to the axle 10 and the wheels 11 . The second motor / generator 3 is connected to the transmission 4 at a point on the transmission 4 close to the output. The transmission can selectively disengage the engine 1 or the individual motor / generators 2, 3 using no or one, two or three clutches.

[0086] The transmission system comprises a drive shaft 15 and a differential 9, both of which may be part of the transmission 4 or separate from the transmiss...

Abstract

The present invention relates to plug-in hybrid propulsion systems in which the energy storage elements of the hybrid drivetrain can be charged with externally supplied electrical power as well as energy from the engine or regenerative braking. The present invention is a plug-in hybrid system with a rapid energy storage and delivery system. In a preferred embodiment, the invention includes a fuel powered engine, battery, fast energy storage system, power converter, controller, drive motor, power distribution system and transmission system. Additionally, the present invention relates to plug-in hybrid systems that provide service to electrical utilities when the vehicle is connected to the utility grid.

Description

technical field [0001] The present invention relates to plug-in hybrid propulsion systems for cars, trucks and buses in which the energy storage elements of the hybrid drivetrain can be charged using externally supplied electricity as well as energy from the engine or regenerative braking. [0002] In particular, the present invention relates to plug-in hybrid systems capable of providing service to electrical utilities when the vehicle is connected to the utility grid. Background technique [0003] Existing products commonly found on the market include conventional hybrids such as the Toyota Prius, Honda Insight and Ford Escape Hybrid. Even more relevant to this invention is the prototype DaimlerChrysler Sprinter plug-in hybrid van. [0004] A major problem with existing conventional hybrid systems is that the full potential of conventional hybrid propulsion systems cannot be achieved due to the limited range of full electrification. This problem can be addressed by allow...
