Demonstration of new high-performance batteries in coal-mining scoops. Final technical report
The program objective was to demonstrate the performance features of an improved battery system in underground coal haulage applications that might increase productivity for the equipment and lower operating costs for the mine operator. The program was initiated with an investigation of several mine facilities to evaluate the operation of battery powered coal haulers. A design concept and specification for the nickel-iron battery was developed for use in a S and S Corporation CX-2 UNATRAC Coal Hauler. An 800 Ah, 132 VDC nickel-iron battery system was assembled and tested. Field tests were conducted at an aboveground test track to simulate actual mining environments. Test results indicated that the nickel-iron battery could provide a range of 40 to 70% additional trips per battery charge cycle. Auxiliary hardware functioned as designed and demonstrated the automatic battery maintenance features. A relatively high number of cell package failures occurred during this test period that precluded an underground demonstration. As a result of the performance improvements demonstrated by the battery and the potential for an additional increase in performance due to recent advancements in electrode technology, the final phase of the program was redirected to design and test additional prototype cells addressing the packaging problems encountered during the field test period. The increased energy storage and high rate charging for the nickel-iron system does provide the mine operator with more options on operating the equipment within a section by extending the useful service time of the battery for a shift or multiple shift operation.
