Truck Electrification Process Diagrams

A DOE project called the "More Electric Truck" is working on making diesel engines for long-haul trucks more efficient. The project aims to take loads off the engine by using electrically powered accessories instead of mechanically powered ones. Electrical power allows the accessories to operate independently of the engine, so they can perform at the precise speed, pressure, or flow rate required.

This three-step diagram illustrates how conventional heavy trucks would deploy technology resulting from DOE's planned Essential Power Systems Program. The final step demonstrates hybrid electrification under the Heavy Hybrid Electric Truck AHHPS Program.
This diagram depicts a plausible More Electric Truck model. It shows various fuels traveling to internal combustion engines, turbines, and hydrogen reformers. These power sources drive electric generators that help satisfy the vehicle's accessory load.
