“General Motors and ABB today 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.”
