GM and ABB demonstrate further use for EV batteries
General Motors (GM) and ABB are conducting research into reusing batteries from the GM Chevrolet Volt once they are no longer required in electric vehicles (EVs).
Research conducted by GM predicts that the secondary use of 33 Volt batteries will have enough storage capacity to power up to 50 homes for about four hours during a power outage.
The automotive company has been working with ABB to identify joint research and development projects that would reuse Chevrolet Volt battery systems, which will have up to 70 per cent of life remaining after their automotive use is exhausted.
On 19 July, GM and ABB demonstrated an energy storage system that combines GM’s EV battery technology with a grid-tied electric power inverter.
The two companies are building a prototype that could lead to Volt battery packs storing energy, including renewable wind and solar energy, and feeding it back to the grid.
According to a statement the system could store electricity from the grid during times of low usage to be utilised during periods of peak demand. The battery packs could also be used as back-up power sources during outages and brownouts.
