Hybrid 320 Ton Off Highway Haul Truck: Quarterly Technical Status Report 1
The mine proving ground to be used for the hybrid off highway vehicle (OHV) demonstration was visited, to obtain haul route profile data and OHV vehicle data. A 6500-ft haul mission with 7% average grade was selected. Enhancements made to a dynamic model of hybrid missions provided capability to analyze hybrid OHV performance. A benefits study defined relationships between fuel and productivity benefits and hybrid system parameters. OHV hybrid system requirements were established, and a survey of candidate energy storage technology characteristics was carried out. Testing of the performance of an existing power battery bank verified its suitability for usemore »
