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. This compares with €6,000 to more than €18,000 for a full hybrid or electric vehicle. —Guy Morris.

The development team retained the existing conventional front-wheel-drive system of the Combo but added an electric drive, powered via low-cost valve regulated lead-acid (VRLA) batteries, to the rear wheels. Developed to reduce the carbon emissions of inner-city driving, the ADDZEV system was developed using a standard Vauxhall Combo van.
