The 2025 Ram 1500 Ramcharger has a liquid-cooled 92 kWh battery pack and is paired with a 3.6-liter V6 engine on-board 130 kW generator, sending power to a 250-kW front electric drive module and 238-kW rear electric drive module (EDM). The EDMs combine the motor, gearbox and inverter along with all-wheel-drive capability. The one EDM on the front axle has an automatic wheel-end disconnect that allows the front wheels to spin freely in certain conditions, maximizing efficiency. The second EDM is positioned on the rear axle with an optional electronic-locking rear differential.

Power flows in sequence from the 3.6-liter V-6 engine to the on-board 130-kW generator. The engine generates mechanical power that is converted to electrical power by the generator. The electrical power can be used to charge the battery when the battery is depleted or if the driver wants to preserve the battery power. It can also be applied to the high-voltage bus where the EDMs can use the generator electrical power plus the battery electrical power to provide maximum power to the wheels. There is no direct mechanical path from the engine to the wheels.

The 3.6-liter Pentastar V-6 engine is specifically adapted for powering the onboard generator, with packaging to make room for the front EDM. The on-board generator mounts directly to the engine while a power inverter module mounts on the vehicle and connects to a junction box.

A liquid-cooled 92-kWh battery pack has a pouch cell format in a parallel configuration. Ramcharger’s battery is positioned under the floor in the center of the truck and maintains a flat floor. Ram is capable of external recharging with the ability to add up to 50 miles of all-electric range in approximately 10 minutes with 400-volt DC fast charging at up to 145 kW.
