GM and ABB Create Uninterruptible Power Supply for Homes Using Old Volt Batteries
November 16th, 2012
General Motors has announced that it has teamed up with a company called ABB to come up with away to use the batteries inside of the Chevrolet Volt extended range electric vehicle after they’re no longer usable in the car. The batteries used in EVs have typically only used up about 30% of their total life when they’re no longer viable for automotive use.
The two companies have come up with an interesting secondary use for the batteries that was shown off recently at the GM Electrification Experience.
The partnership resulted in a prototype uninterruptible power supply that used five Volt batteries. The prototype system provided 25kW of power and 50kWh of energy during the event. In fact, the batteries inside the prototype system powered all of the lighting and audiovisual systems needed for the Electrification Event.
The idea is that one of these five battery modular units would be able to provide two hours of uninterrupted electricity to between three and five average American homes during a power outage. The uninterruptible power supplies could also be used to keep industrial facilities operating as well. There’s no indication of when these uninterruptible power supplies might be available on the commercial market.
