The heavy-hauling PHEVs use Electrovaya's 12-kWh lithium ion "SuperPolymer" battery system that provides enough juice to move the light-duty truck for up to 20 miles in electric-only mode. Additionally, the plug-in Ram comes packing a 5.7-liter Hemi V8 gasoline engine, a two-mode hybrid transmission and a 6.6-kilowatt on-board charger.
Chrysler, along with Electrovaya, will build a test fleet of 140 PHEV Ram thanks, in part, to a $48-million grant from the American Recovery and Reinvestment Act DOE Vehicle Electrification Program and a $5-million grant from the Canadian government. The Ram plug-in project is a $97.4-million effort that will soon expand to another ten locations. Earlier this year, Chrysler sent 10 PHEV Rams to Yuma, AZ and Clark County, NV.
28 plug-in hybrid electric vehicles (PHEV) will be supplied to San Francisco and Sacramento as part of a demonstration project by Chrysler Group LLC
Real world city miles to be accumulated on demonstration vehicles over the next three years
Fleet of vehicles developed in partnership with U.S. Department of Energy
Ram 1500 plug-in hybrid test trucks will be used to evaluate city drive cycles, charging performance, fuel economy and real-world performance
August 2, 2011 , Auburn Hills, Mich. - Chrysler Group LLC, working in partnership with the U.S. Department of Energy (DOE), will deliver 14 demonstration fleet Ram 1500 plug-in hybrid electric vehicle (PHEV) pickup trucks to officials in both San Francisco and Sacramento this week.
The 28 PHEV Ram 1500 pickups to be delivered by Abdullah Bazzi, senior manager of the Chrysler Group's advanced hybrid vehicle project, are part of a national demonstration fleet of 140 vehicles that will be used during the next three years to evaluate customer usage, drive cycles, charging, thermal management, fuel economy, emissions and impact on the region's electric grid. In addition to San Francisco and Sacramento, ten other partners across the United States will receive vehicles for demonstration and testing purposes.
Earlier this year, Chrysler Group LLC delivered 10 Ram 1500 PHEV trucks to the city of Yuma, Ariz., to take full advantage of hot weather and conduct thermal testing in the desert southwest.
Strictly a demonstration program, there are no plans for a production version of the PHEV Ram 1500 truck at this time.
Cities and states were selected to evaluate temperature extremes, urban traffic cycles and diverse climates and geographies from North Dakota, Massachusetts, Hawaii and Arizona. California cities include San Francisco and Sacramento.
The Ram 1500 PHEV includes a liquid-cooled 12.9kWhr lithium ion battery pack and a 6.6 kilowatt (kW) on-board charger. Additional features include AC power generation of up to 6.6kW; directional charging; reverse power flow and full regenerative braking used to capture more energy. For fuel economy improvements, the front axle of the four-wheel-drive automatic transmission can be disconnected when not needed. The powertrain also includes a 5.7-liter HEMI® V-8 engine and a two-mode hybrid transmission. The 5.7-liter Hemi is equipped with a Fuel Saver technology that improves fuel efficiency at highway speeds by shutting down fuel delivery to up to four cylinders.
The battery pack is located under the second-row seat of the pickup and is liquid cooled to help maintain a consistent battery temperature. For on-the-job electrical power tools, a 240 volt/30 amp four-prong outlet and 120volt/20amp duplex outlet power strip is located in the rear box.
"Cities have been carefully selected to help the Chrysler Group LLC collect a wide range of data," explained Abdullah Bazzi, senior manager of Chrysler's advanced hybrid vehicle project. "Both San Francisco and Sacramento offer heavy traffic and urban driving that are ideal city test cycles. The constant charging will allow us to measure the impact on battery life and charging efficiency."
The choice of a Ram 1500 pickup truck was based upon two-speed transmission technology that was readily available.
Urban use also will be tracked to measure battery performance and overall hybrid efficiency with the demonstration fleet of pickups. Other uses include military bases where vehicles will be able to provide power back to the electric grid in what is termed "reverse power flow" of up to 6.6kW.
Funding for the program in part is provided by the American Recovery and Reinvestment Act of 2009 through the Transportation Electrification Initiative sponsored by the DOE. The grant, totaling $48 million from DOE and $49.4 million from Chrysler Group LLC, was designed to develop vehicles that will be cost-efficient for consumers, satisfy safety concerns of daily travel without recharging and help reduce dependence on foreign oil.
The Chrysler Group LLC also is developing a similar fleet of 25 Town & Country minivans with plug-in hybrid technology for demonstration and evaluation that will be allocated to select cities later this year.
