US Patent:

7224132, May 29, 2007

Filed:

Jan 22, 2004

Appl. No.:

10/761313

Inventors:

Chahee Peter Cho - Centreville VA, US
Eun S. Kim - Centreville VA, US

Assignee:

Wavecrest Laboratories, LLC. - Rochester Hills MI

International Classification:

H02P 1/00

US Classification:

318139, 290 9, 290 17, 320136, 320149, 180 651

Abstract:

A portable range extender is provided for an electric vehicle having a vehicle controller, and an electric traction motor powered by a battery. The portable range extender has an engine, a dynamoelectric machine coupled to the engine by a shaft and electrically connectable to the vehicle, and a range extender controller for controlling operations of the range extender independently of the vehicle controller. The range extender controller monitors voltage of the battery to automatically activate the range extender when the battery voltage is less than a first threshold value and automatically deactivate the range extender when the battery voltage reaches a second threshold value. The dynamoelectric machine operates as a motor for starting the engine when the battery voltage is less than the first threshold value. In response to prescribed engine conditions, the range extender controller operates the dynamoelectric machine as a generator driven by the engine to generate electric power supplied to the vehicle.

Bluwav Systems, LLC - Rochester Hills MI

International Classification:

F02B 63/04

H02P 9/04

US Classification:

290 1A, 290 40 B

Abstract:

A portable range extender can be used to supply electrical power to an electric vehicle operable by an electric traction motor. The portable range extender includes an engine, a dynamoelectric machine coupled to the engine by a shaft, an autonomous range extender controller for controlling operations of the range extender independently of a controller for the vehicle, and circuitry associated with the engine and machine. To start operation, electrical energization is applied from the vehicle battery to the dynamoelectric machine for operation as a motor to drive the shaft. As the shaft accelerates, the rotational speed of the shaft and the temperature of the engine are sensed. When the speed and temperature obtain predetermined thresholds, fuel is supplied to the engine and ignition is activated. The engine then operates as a prime mover to drive the shaft in lieu of the machine. After a period of engine prime mover operation, the machine is activated for operation as a generator to provide an electrical current output for charging the battery or supplying energy to the traction motor.

International Classification:

B60K 6/00

US Classification:

180 652, 180 654

Abstract:

A portable range extender can be used to supply electrical power to an electric vehicle operable by an electric traction motor. The portable range extender includes an engine, a dynamoelectric machine coupled to the engine by a shaft, an autonomous range extender controller for controlling operations of the range extender independently of a controller for the vehicle, and circuitry associated with the engine and machine. The range extender and its controlling circuitry are self contained within an enclosure. The enclosure is partitioned to form two sections, a first section housing the dynamoelectric machine and the second section housing the engine. Windows in the enclosure provide a path for air cooling of the range extender components. Air cooling is facilitated by a first set of cooling fins mounted on the rotor of the dynamoelectric machine at an end proximate an air inlet window, a second set of cooling fins mounted on the rotor of the dynamoelectric machine in the vicinity of an opening in the partition, and a third set of cooling fins mounted on the engine at the opposite side of the partition opening.

Abstract:

An O-GlcNAcase-specific inhibitor and substrate are engineered by the extension of the N-Acetyl Moiety of O-(2-acet-amido-2-deoxy-D-glucopyranosylidene)amino-N-phenylcarbamate (PUGNAc). The reagent substrate includes a fluorophor and the inhibitor. This reagent substrate is for high-throughput analysis of O-GlcNAcase within cellular assays and imaging agent for the in vivo analysis of O-GlcNAcase.
