Lithium Ion to Replace NiMH ‘in Hundreds of Hybrid Buses’
Indiana’s EnerDel reports a five-year agreement to supply as many as 48 of its lithium ion battery packs annually to replace nickel metal hydride units “in hundreds of hybrid buses” operated by the Seattle area’s King County Metro Transit.
The agreement follows an EnerDel demonstration pack’s operating “failure-free in regular passenger service for over one year,” states a release.
EnerDel will supply its PP320-689-LP Vigor+ ESS – energy storage systems – through 2019.
The Seattle area has upwards of 770 hybrid buses, and will replace batteries as they fail or reach their end of life (F&F, April 14).
Fits the Footprint, With Greater Capacity
The first delivery of EnerDel’s Vigor+ packs is slated for next month, EnerDel said Tuesday, “and will initiate ESS upgrades for its New Flyer Allison Hybrid bus fleet.”
“The transit authority required a complete ESS to fit into the footprint of its current NiMH battery systems,” EnerDel says, noting that the “retrofitted solution needed to be virtually seamless, and have the ability to maintain established diagnostic reporting.”
EnerDel says its product “met and improved upon the direct replacement requirements,” in that the 20 kilowatt-hour ESS “delivers over three times the rated energy of the existing NiMH system.”
‘Lower Costs, Multiple Resources’
“Our technology has proven to surpass the incumbent technology, yielding enhancements in performance and warranty, offered as a lower-cost alternative for municipalities,” EnerDel CEO Michael Canada said in a release.
“The contract we have established with EnerDel will meet the high standards set by the original vendors while helping to lower costs for the county and provides multiple resources in case one part stream dries up,” said George Stites, King County Metro’s superintendent of fleet engineering.
