FreeWire Tech Raise Millions, Starts Shipping Battery-Boosted Fast Chargers

Startup FreeWire Technologies raised another $25 million to commercialize its electric car chargers, which are designed to reduce the infrastructural costs of installation.

The Bay Area company finished development of its Boost Charger, which delivers fast charging (up to 120-kilowatt output) while minimizing stress on the local power grid with the help of a built-in 160-kilowatt-hour battery. That storage capacity allows fast charging while lowering the instantaneous pull from the grid to resemble a Level 2 charger (roughly 10 kilowatts), which in turn reduces costly grid upgrades required to install the system in the first place.
