With a familiar 5.7 liter HEMI V-8 gasoline engine ready to work to full diligence, the Ram 1500 PHEV incorporates a much more complicated powertrain. Primarily power for the Ram 1500 PHEV for a maximum of 20 miles of travel comes from an electric motor fed by the capacity of a liquid-cooled lithium-ion battery. Utilizing a Superpolymer battery supplied by Toronto, Ontario-based company Electrovaya is located comfortably underneath the rear seat. This particular 12.9-kilowatt power supply is advertised in providing low construction cost and is manufactured without the release of toxins or greenhouse emissions. Besides serving an active role in the Ram 1500 PHEV’s propulsion system, the lithium-ion battery will also be demonstrating itself as a mobile electrical power source for 120 and 240-volt power tools.
