Case Studies

PHEV 4X2 Pickup Truck

The California Automobile Association and Alameda County awarded a grant to develop PHEV a pickup for its transportation division. The Matheson Group was contracted to develop a prototype PHEV based on a 4×2 Dodge Dakota.

The completed vehicle featured a permanent magnet motor (PMM) which was mounted between the body and frame. The motor was connected to the driveshaft via chain and sprockets. This configuration allowed for all-electric propulsion when the transmission was in Neutral, or continuous hybrid operation when in Drive.

A removable, 23 kWh battery pack was fixed to the bed of the truck. A battery management system (BMS) was installed to ensure safety and cell balancing.

A custom operating system allowed the operator to chose which driving mode best fit service needs.

BEV 4x4 Pickup Truck

The Matheson Group worked with a winner of California Clean Tech Open Transportation competition to develop a proof-of- concept battery electric 4×4 truck.

The goal was to integrate extended-range electric drive components into vehicle engine bays vacated by their old gas drive trains, eliminating the need for custom sheet metalwork and welding which would will allow for fast conversion of existing cars and light trucks to battery-electric or extended-range electric drive vehicles.

The prototype developed featured a battery range extender, a DC electric traction motor coupled to the OEM manual transmission and lead-acid batteries recessed into the bed of the tru

PHEV 4X2 Pickup Truck WITH V2G

EVAOS delivered fifteen Vehicle to Grid (V2G) PHEV pickup trucks under the DOD V2G Program and one V2G PHEV pickup truck to the US Forest Service in Juneau, Alaska.

EVAOS-quipped trucks retain their original gas engines and transmissions, providing for ease of hybrid system installation. Three different driving modes are available:

  • All-electric mode for maximum fuel savings
  • Hybrid mode for longer trips or extra towing power
  • Conventional mode for extended range


EVAOS systems can provide exportable power for external electrical equipment in locations where the electrical grid is unavailable.
