A team of Penn State researchers is developing more cost-effective ways to prolong the life of valve regulated lead-acid (VRLA) batteries, such as those applied in Norfolk Southern Railway No. In this paper, the cell voltage and pressure of new and dead VRLA batteries are monitored during testing to determine the cause of death of the cells.
The use of a carbon-enhanced valve-regulated lead-acid (VRLA) battery will help maximize energy recuperation during deceleration, fully realizing SpeedStart’s potential for high power generation and hence electrical energy recovery. 22 nd International AVL Conference “Engine & Environment”). —Guy Morris.
Stop-start vehicles (SSVs) (also called micro-hybrids or idle-stop vehicles), enable stopping the engine when the vehicle slows or is idling and subsequent restart, thus requiring more robust batteries and starter systems than are found in conventional internal combustion engine (ICE) vehicles.
Axion Power International, Inc, the developer of advanced lead-carbon PbC batteries and energy storage systems ( earlier post ), has entered a strategic relationship with ePower Engine Systems LLC. the diesel engine powers a generator that in turn provides power directly to the traction motors.
Other international companies involved are powertrain developer and systems integrator AVL Schrick based in Austria and Germany, springy materials specialist Mubea also from Germany, and Provector, a leading expert in battery management systems, based in the UK. —Allan Cooper, European projects coordinator at ALABC.
A collaboration led by the UK’s Cranfield University has developed a retrofit plug-in hybrid conversion system for a conventional internal combustion engine vehicle.

In April, Axion Power International Inc received an order from Norfolk Southern Corp (NS) for PbC lead-carbon batteries for use in an all-battery-powered switcher locomotive. All of these things that are new put more and more strain on the battery and create the need for the battery to have excess energy. Source: NS. Click to enlarge.
