2006 Phoenix Motorcars

All-Electric Vehicle with advanced nanotechnology Lithium Titanate battery.

I was the Science and Technology Specialist for systems integration. Responsible for battery pack wiring configuration and interface to motor controller and vehicle 12V electrical subsystem. Also designed fault-tolerant interlock loop that included secondary high-rate charge port.

As the Manager of Business Development for Altairnano, I handled the debut demonstration at the California Clean Air Show in September 2006.

2003 Segway

I was the lead Systems engineer for the lithium-ion battery pack system. Wrote algorithms for lithium battery control. Specified design for lithium battery management electronics. Resulted in 4 patents and 6 pending. Tested battery pack performance and compliance. Commuted for 6 months on a Segway. (photo shows a Segway in a radiation chamber)

2002 Delphi Energen 10 Hybrid

Integrated Starter Generator (ISG) Hybrid

I was the systems engineer for a hybrid 48V battery using lead-acid (PbA) combined with nickel metal hydride (NiMH). Awarded patent US 6,577,099 Method and Apparatus for Providing and Storing Power in a Vehicle for the hybrid battery design.

The ISG system was built into a Mercury Mariner.


During 2000-2002, I worked to
maintain Delphi's privately held EV1.

I routinely commuted in this car
over a period of several years, and
learned the best practices of
efficient driving.

It remains pristine in a museum.

2002 Delphi Energen 5 Hybrid

Belt Alternator Starter (BAS) Mild Hybrid

Systems engineer for lead-acid battery that was coupled to a 5kW belt alternator starter. Built into Peugeot subcompact.

2001 BMW Fuel Cell Hybrid

Test engineer for 31Ah 42V (23kg) high-power Delphi lithium-ion battery pack system that was capable of delivering over 700 Amperes. The battery provided power during BMW's fuel cell startup.

The battery was a Bellcore (Telcorida) plastic lithium ion design, tested and validated on Aerovironment ABC-150 equipment.

1999 "Papillon" Solar Car

Graduate Advisor to the Texas A&M Solar car team. The car was a lightweight space frame using lead-acid batteries and a high efficiency permanent magnet, variable air-gap, axial flux motor.

The solar array was segmented by angular orientation with individual peak power trackers for optimal energy output.

1997 "MACH V" Solar Car

Graduate Advisor to the Texas A&M Solar car team. The chassis was a Nomex honeycomb construction with a permanent magnet axial flux fixed air gap motor. Power was provided by lead-acid batteries and seven solar
arrays segmented by angular orientation.

This car won many awards, including the Winner's Circle for the 1997 Sunrayce.

1995 Hybrid Electric Vehicle

Graduate Advisor to the Texas A&M University HEV Challenge. This car was a converted Dodge Neon with a small 2 cylinder engine, compressed natural gas fuel, 12" advanced DC motor, and lead-acid Horizon batteries.

I was responsible for computer modeling and simulation of the hybrid system and developing control algorithms for balancing energy for the drivertrain, fuel consumption, and batteries.

This car was very fun on the racetrack.

1995 Solar Car

Graduate advisor for 1995 "Aggie Beamer" Solar Car. Space frame construction with suspended flat solar array. Three-wheel design with lead-acid batteries and 5kW coaxial permanent magnet motor.

1994 "T-Star" Electric Vehicle

Converted Geo Metro with a Zinc-Bromine (fluid) battery and twin Solectria permanent magnet motor drives.

This car is still in operation, but with different batteries. Last time I saw it, I could still smell the Bromine.

TEES Utility Van

Full-electric converted GMC Van for utility duty for Texas Engineering Experimental Station (TEES).

My work with the TEES Van closes a full circle with the Phoenix Motorcars utility vehicle.
