This uninterrupted power supply and grid power balancing system was demonstrated at the GM Electrification Experience in San Francisco. Duke Energy, who is right now the largest power utility in the US, was also there to make an announcement that the ABB-GM prototype will be tested on their grid. The prototype unit on show delivered 25 kW of power and 50 kWh of energy which was enough to run all the support lighting and audiovisual equipment in an “off-grid” structure that was used for the event, is that impressive or what? At least we know that our landfills will be less burdened if electric vehicle batteries can be reused creatively. [Press Release]
