General Motors said it has begun using used Chevy Volt batteries to help power one of its buildings.
Under the plan, GM will use first generation Volt batteries to power its IT administration building at its Milford Proving Grounds facility. The company has built out an enterprise data center there.
When Volt batteries expire for use in the car, there is about 80 percent of power storage left. As a result, GM is using the Volt batteries to complement a solar array and wind turbines.
GM's move highlights how secondary uses are emerging for electric vehicle batteries. Scrap Volt battery covers have already been used for things like buildings for animals and nesting areas.
For GM, the five Volt batteries serve as a nice backup power supply and cut down on waste. The batteries can provide back-up power for up to four hours in an outage.
