Why Fast Charging Infrastructure Has Fallen Behind
Ever wonder why there aren’t more Level 3 DC Fast Chargers for EVs right now in your town or on the road when you need one most? It all comes down to affordability as a Fast Charger can cost anywhere from $50K to $150K per port for the hardware alone.
Installing a Level 3 Charger also requires permits, on-site construction, and major electrical upgrades. All that is very expensive for local businesses who have to foot the bill. But a company called ElectricFish has found a way around all that, installing its 350Squared Chargers without the need for a single Grid upgrade and for a fraction of the cost.
This 101 guide lays out Level 1, Level 2, and DC Fast Charging in practical terms:EV Charging Basics
Now fleet operators, convenience stores, and local gas stations can purchase easy-to-install and less expensive Level 3 chargers that convert AC power to DC charging. The 350Squared chargers from ElectricFish can tie into the power grid using a relatively low-power 30-kilowatt AC connection that delivers up to 350 kW of DC power to electric vehicles.
How is this magic possible?
ElectricFish tells us the 350Squared units contain a mighty 400-kilowatt hour lithium-ion battery that offers high power fast charging to EVs. The big battery recharges anytime the draw is under 30 kilowatts. The massive battery inside the 350Squared unit acts as a buffer between the power grid and your EV.
Motor Trend stress-tested the 350Squared charger with its 2026 SUV of the Year, the Cadillac Escalade IQ a few months back. They took the charger out to the Mojave Desert to bake in the sun for five days, saying it delivered 1,119 total kWh over 37 charging sessions. It says the Caddy saw a peak boost of 313 kW during charging.
The unit was unfazed by temperatures of over 100 degrees even though it was backed by an air-cooled 320-kWh nickel manganese cobalt battery. Future versions of the 350Squared will use a liquid-cooled 400-kWh lithium iron phosphate battery.
The 350Squared charger is roughly eight feet long, four feet wide, and seven and a half feet tall, fitting in a standard parking stall. Each unit has two charging cables for both CCS and NACS connection and can boost your EV 50 percent of range in just 10 minutes.
Each unit adds value beyond just charging EVs as they can be used as microgrids to power a business during a blackout. Plus, unlike traditional DC Fast Chargers, the 350Squared charger can be installed quickly. The company says the average install time is just two hours.
Best of all, ElectricFish has a number of ways you can try out its chargers for your business. You can lease a 350Squared charger at zero upfront cost for immediate access to energy and charging. This allows your business to operate a revenue-sharing agreement with ElectricFish. For those who wish to buy a unit, the company tells us initial investment is $33,795 with return on investment in just six months.
ElectricFish has even powered its chargers with diesel generators for events such as Burning Man. It estimates that annual revenue per charger is $156,156. For more information, contact electricfish.co
