Axion Power International Inc. announced its receipt of a second order for PbC batteries designed to operate in string formation to increase fuel efficiency and decrease emissions in Class 8 trucks retrofitted by ePower Engine Systems. The proprietary batteries and design for the ePower Class 8 application were featured recently in FLEETS AND FUELS. The Axion/ePower design is separate and distinct from other Axion trucking product offerings such as APU anti-idling for long-haul truckers who sleep in their cabs, and the dual battery product for hybrid vehicles equipped with "stop/start" technology.
