FreeWire CEO Arcady Sosinov’s company is using “second-life” EV batteries to “reach a cost-competitive part of the market that other energy storage players typically cannot be competitive against,” allowing them to “address new markets that have largely been ignored by other players.”

FreeWire provides “a clean and quiet alternative to diesel generators.”

The washing-machine sized portable charging cart provides 30 kilowatts of peak power and 15 kilowatts of continuous power from the 48 kilowatt-hour system.
