GM and ABB Demonstrate Chevrolet Volt Battery Reuse
Clean Edge News
General Motors and ABB recently showed the next stage in battery reuse, the repackaging of five used Chevrolet Volt batteries into a modular unit capable of providing two hours of electricity needed by three to five average American homes.
The uninterruptable power supply and grid power balancing system was demonstrated during GM’s Electrification Experience. The prototype unit provided 25 kW of power and 50 kWh of energy to power all the support lighting and audiovisual equipment in an “off-grid” structure used for the event.
“GM’s battery development extends throughout the entire life of the battery, including secondary use,” said Pablo Valencia, GM senior manager of battery lifecycle management. "In many cases, when an EV battery has reached the end of its life in an automotive application, only 30 percent or less of its life has been used. This leaves a tremendous amount of life that can be applied to other applications like powering a structure before the battery is recycled.”
GM and ABB last year demonstrated how a Chevrolet Volt battery pack could be used to collect energy and feed it back to the grid and deliver supplemental power to homes or businesses.
ABB’s research center in Raleigh, N.C., conducted the research and development, and ABB’s Medium Voltage business unit in Lake Mary, Fla., is managing the proof-of-concept testing, market research and product development. As the world’s largest EV fast-charging company and leader in smart grid and energy storage, ABB works with other auto companies, battery manufacturers and utilities to help make electric power and industrial operations more productive and efficient.
GM is focused on assuring battery systems used in future Chevrolet, Buick, GMC and Cadillac vehicles provide environmental and societal benefits beyond their use in the vehicle. Long before a battery is recycled, secondary use provides the opportunity to fully utilize the battery resource.
