Penn State researchers developing methods to prolong operating life of valve regulated lead-acid batteries; electric locomotive as example

Green Car Congress

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 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

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. Micro-hybrid testing against VRLA. That prototype cube serves as the design cornerstone for the new residential units, and has been housed at Clover Lane since Axion’s test phase began last summer.
