Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

Compared to advanced lead-acid batteries, the PbC batteries: Support higher [10-20x] charge acceptance and faster recharge [5-10x] in partial state-of-charge (PSOC) applications; Offer an 4x increase in cycle life in 100% depth-of-discharge applications; and.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

A forklift equipped with an EERS module will increase the useable time of the battery pack by 30% allowing an operator to complete a full eight hour shift on a single charge of the lead acid storage pack. The use of the module also prevents the battery from deep cycling, extending the life of the battery.
