Electric Power Research Institute (EPRI), Eaton, Ford and the California South Coast Air Quality Management District (AQMD), are developing a plug-in hybrid electric vehicle (PHEV) system for utility trouble trucks and vans.
In Phase 1 of the project, four prototype PHEV trucks based on a Ford F-550 truck chassis will undergo testing this year with the utility partners in the project: Southern California Edison (SCE), Los Angeles Department of Water and Power (LADWP), and Pacific Gas & Electric (PG&E). Phase 2 will expand to 50 trucks and E-450-based vans for utility and public fleets.
The PHEV trouble truck is smaller than the hybrid trouble trucks already being developed and tested through the Hybrid Truck Users Forum (HTUF). (Earlier post.) Smaller trucks have an easier time navigating small access roads and alleys to get to work locations.

The F-550 PHEV uses either the 6.8L V10 gasoline or 6.0L V8 diesel engine in a parallel, pre-transmission hybrid architecture.
Design goals for the truck include:
Reduced fuel consumption, reduced emissions, and reduced operating costs compared to stock vehicle, while providing equivalent or superior performance to the base truck in all modes including full cabin air conditioning while operating all accessory loads.
The ability to use grid electricity for part of the vehicle’s daily duty cycle and incorporate regenerative braking with four-wheel drive capability.
30 kW of standby AC generation capacity with 5kW of export power and standby operation time of at least six hours, running the bucket, power tools, lights, and accessories without the need to run the engine.
Advanced battery packaging, charging, and cooling systems lasting the intended vehicle life of five years.
The final design will consider manufacturability, vehicle integration with minimal rework, component costs, and durability to enable approvability by Ford MVE engineering as a ship-thru product and migration of this powertrain to similar class commercial vehicles.
EPRI will work with Eaton to apply modeling to this 17,500 GVW plug-in hybrid prototype based on current work underway to build an Eaton hybrid 30,000 GVW truck.
PG&E, SCE and LADWP will each test the first PHEV utility truck prototype for a defined period and help generate and finalize vehicle specifications. PG&E and SCE will demonstrate diesel PHEVs, and PG&E and LADWP will demonstrate gasoline PHEVs. Additional funding from the California Air Resources Board and other entities is being pursued to add the 46 additional demonstration vehicles in the US and Canada.
