The 2019 Dodge Ram 1500 eTorque basically has an electrical generator and not a true alternator. The eTorque technology provides the electricity for the vehicle. Additionally, it keeps the 12-volt battery charged, the motor/generator quickly restarts the motor when the automatic stop/start system is used, and it adds assist as a mild-hybrid system. The 2019 Ram is technically a hybrid with either of the two gasoline engines offered, V6 or V8.
While most of the Ram 1500’s electrical systems still use traditional 12-volt power, eTorque is actually a 48-volt system. It uses a DC-to-DC converter to change 48 volts to 12 (for the traditional electrical systems), and a battery pack about the size of a small suitcase that can store up to 430 watt-hours of energy. The total eTorque system, cables and all, adds about 100 pounds of weight to the truck. The battery pack is located inside the rear wall of the cabin.
