"The American auto industry is in the middle of a sweeping transformation, one that goes far beyond just selling more electric cars. The infrastructure required to support battery-powered vehicles is expanding rapidly too, and the technology underpinning it is evolving just as fast. One of the more notable developments is the rise of large EV charging stations powered by batteries that can boost power and supplement the grid."
"What sets this site apart, though, isn't charging speeds. It's how the electricity is stored and deployed. Typical fast chargers draw power directly from the local electricity grid in real time. A battery-backed charging hub, by contrast, adds an on-site buffer in the form of large containers filled with lithium-ion cells. Electricity is drawn from the grid during off-peak hours (when energy is cheaper), stored in those batteries, and then dispensed to EVs when drivers plug in."
New York City will get a 44-stall, battery-backed EV charging hub in Brooklyn's Williamsburg neighborhood that opens in the second quarter. The hub will feature 44 chargers serving 88 parking spaces and is led by XCharge and Energy Plus. Each charger can deliver up to 300 kilowatts of power, faster than most existing Superchargers. Large on-site lithium-ion battery containers will store grid electricity during off-peak hours and dispense it during peak demand. The battery buffer reduces peak-hour charging costs and supplements the local grid, enabling high-power fast charging without solely relying on real-time grid capacity.
