Fuel Cell Mineloader
The objectives of this project included developing a zero-emissions fuel cell equivalent to a Caterpillar-Elphinstone R1300 loader, as well as a mine-safe refueling system based on electrolysis of water. The system would then be evaluated for safety and productivity in an underground mine in Nevada. AeroVironment served as energy system integrator for the U.S. Department of Energy Fuel Cell Mineloader project. This included providing fuel cell balance of plant, battery pack and battery management design, hybrid control system and communication between battery pack and fuel cell system, power electronics (to tie in fuel cell, battery pack and motor), fueling from fuel storage, and interface with motor controller and other system components.
