M5BAT 5MW storage system integrates multiple battery technologies

Green Car Congress

electric utility company, battery manufacturers Exide and beta-motion and inverter manufacturer SMA Solar Technology AG (SMA) have joined forces to build the first multi-technology, modular large-scale 5MW battery storage system. The unique feature of the M5BAT (Modular Multimegawatt, Multitechnology Medium-Voltage Battery Storage System) storage system lies in its modular design, which combines different battery technologies for optimal use.

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. 999—the first all-electric, battery-powered locomotive in the United States. A leading cause of damage and death in lead-acid batteries is sulfation, a degradation of the battery caused by frequent charging and discharging that creates an accumulation of lead sulfate.

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

The battery-electric NS-999, “under the long hood”. 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. Axion Power said this first $400,000 purchase order is part of a $475,000 total purchase order, that will be used in the commissioning of Norfolk Southern’s NS-999 ( earlier post ). PbC batteries.
