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.
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.
The paper was jointly authored by CPT engineering director and chief technical officer Guy Morris with Mark Criddle, Mike Dowsett and Toby Heason from CPT and Dr. Paul Kapus and Matthias Neubauer from AVL. TGDI engine and close to the 146 g/km of the current Passat 2.0L common rail TDI engine. common rail TDI engine.
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. million SSV units sold in 2013.
The low-voltage technology enables aggressive, near-term down-sizing and down-speeding of existing engine families, the partners say. Recalibration of the engine increases power from 120 hp to 140 hp (89 kW to 104 kW) and torque from 200 to 275 N·m (148 to 203 lb-ft). The demonstrator features a Valeo electric supercharger.

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. The proposed system uses a very small starter battery, the sole function of which is to start the engine. Micro-hybrid testing against VRLA. Source: NS.
