You have probably heard someone complain about waiting in line at an EV charger. But the real wait happens long before any driver pulls up. It happens when a site operator applies for a transformer drop and the utility tells them it will take 52 weeks. Or 72 weeks. Sometimes longer.
Alex Urist, co-founder of XCHARGE North America, has spent years navigating these delays. His company's solution is deceptively simple: put a battery in the charger. The result is GridLink, a bi-directional DC fast charger with integrated energy storage that cuts deployment timelines from years to months.
The Grid Problem Nobody Talks About
EV adoption gets plenty of headlines. Grid limitations do not. Yet they represent one of the biggest obstacles to getting charging infrastructure in the ground.
"One of the biggest limitations on getting EV infrastructure in the ground really is the grid," Urist explained. "We don't have enough power in every single area to power high speed chargers without pulling a new service, dropping a new transformer, upgrading what we have going on there."
The numbers tell the story. According to Wood Mackenzie research, lead times for power transformers average 128 weeks, with some distribution transformer classes experiencing price increases of 95 percent since 2019. The National Renewable Energy Laboratory found that approximately 55 percent of in-service transformers are at least 33 years old and near the end of their expected lifespan.
The problem compounds when EV charging competes with other electricity demands. Data centers, renewable energy projects, and building electrification all require grid upgrades. A single on-road charging station can have the power demand of a small town.
"You might get dropped in the queue dependent on how big of a build you are, who you are, if there's a data center that might be coming up that needs to allocate a little bit more in that nodal center," Urist said.
The Battery Solution
XCHARGE's GridLink integrates a 215 kilowatt-hour battery directly into the DC fast charger, flexible up to 430 kilowatt-hours. The unit can take energy from the grid, store it in the battery, and use that stored energy to charge vehicles at up to 300 kilowatts output.
The math changes when you add a battery. Instead of requesting the full power capacity you need to charge vehicles at peak rates, you request less from the grid and let the battery supplement the difference.
"When you integrate energy storage into your overall architecture, you can start to cut the queue based on not needing as much power from the utility company," Urist explained. "They're a little bit more flexible as far as where they can slot you in."
A project in Brooklyn illustrates the concept. XCHARGE is deploying 44 GridLink units underneath the Williamsburg Bridge, representing nearly 10 megawatt-hours of energy storage. But the interconnection request is not for 10 megawatts. It is closer to four or five megawatts of maximum intake.
The deployment timeline difference is dramatic. Where a traditional DC fast charger project might wait 52 weeks or more for a transformer drop, battery-integrated projects can complete in as fast as three months once permitting clears.
Beyond Just Charging
The GridLink platform does more than charge cars. It can take up to 60 kilowatts of solar direct into the battery via DC-DC connection. It can discharge energy back to buildings during blackouts. In deregulated energy markets, it can provide power back to the grid during demand response events.
"What's been hard in the capital stack of EV charging is that it's a straight one-to-one purpose," Urist noted. "You install a charger, it's so that you can make money off of electrons that you're vending into vehicles. There's no ulterior benefit that's going to the building."
Battery-integrated chargers change that equation. A site can use the battery to shave peak demand charges from the building itself, potentially saving significant money independent of any EV charging revenue.
According to RMI analysis, electric vehicles have a 9 percent lower total cost of ownership than equivalent fossil fuel vehicles even when charging infrastructure costs are included. Adding grid services revenue to that equation strengthens the business case further.
The Demand Charge Problem
Utility rate structures can make or break an EV charging business model. Demand charges represent one of the biggest wildcards.
"In some utility jurisdictions, it may be that if you exceed a certain rate that you're supposed to have on site, if you exceed that at one point for five minutes or any point during the month, you might end up paying up to that new rate amount for the entire month," Urist explained. "You can pay up to 80 percent more than what you're expecting to pay."
A model projecting three-year ROI can quickly stretch to four, five, or longer if demand charges spike unexpectedly. Battery-integrated systems help manage this risk by storing energy during low-demand periods and dispensing it during peak times.
Gateway Fleets, an XCHARGE partner that leases delivery vehicles and provides charging, uses two GridLink units with 430 kilowatt-hour batteries to manage exactly this challenge. Operating in California, one of the most challenging utility rate regions in the country, they balance charging schedules against driver availability and peak demand periods.
"When you truly can balance your methodology, it makes a lot of sense," Urist said.
Fleet Economics
Fleets have emerged as early movers in EV adoption, driven by straightforward economics. According to Coltura's Q4 2025 analysis, U.S. electric vehicle drivers saved an average of 8.3 cents per mile on fuel and maintenance compared with gas cars. The U.S. Department of Energy reports that EVs cost approximately 40 percent less per mile in maintenance than conventional vehicles.
"We've run the numbers alongside with some of our customers of what the total fuel savings costs look like," Urist said. "You see a reduction of nearly 30 percent on overall long-term maintenance costs and fuel costs."
The battery-integrated approach solves a particular fleet challenge. Depot charging requires high power availability at predictable times. Rather than requesting massive grid connections that may take years to install, fleets can deploy battery-integrated chargers that manage the load intelligently.
Real Estate Is Everything
If there is one insight Urist emphasizes above all others, it is the importance of real estate selection.
"Real estate is number one in EV charging as a whole," he said. "What energy storage helps to do is make it more capable or more able to pick new or better real estate."
Hotels make particular sense, positioned at major intersections along interstate corridors but rarely thought of as charging destinations. Strip malls offer opportunities tied to activity, where someone getting a haircut or having dinner could charge while they go about their day. Dealerships need chargers for test drives and service but often lack the grid capacity for traditional DC fast charging.
"Where power wasn't available before, if you bring a battery in and you drop it in, you can effectively power more," Urist noted. "You can get into spaces that were harder to see."
Gas stations seem obvious but present complications. Underground fuel reserves create complicated permitting procedures. Digging around existing infrastructure requires understanding exactly what lies beneath. Battery-integrated chargers that use existing building power and minimal trenching become much more viable.
The Perceptive Availability Problem
EV adoption faces a chicken-and-egg challenge. People hesitate to buy EVs because charging infrastructure feels inadequate. Charging infrastructure struggles to justify investment because EV adoption lags projections.
Urist frames the solution as perceptive availability of charging. Drivers need to stop thinking about where they will charge just as they stopped thinking about where they will find gas.
"It just needs to get to that where driving an EV, you don't have to think about where you're going to charge your vehicle because it just makes sense," he said.
Battery-integrated chargers accelerate this transition by enabling deployments in more locations, faster. Every hotel, strip mall, or dealership that could not justify a traditional DC fast charger due to grid constraints becomes viable when battery storage is part of the equation.
Looking Ahead
Urist sees the next five years bringing a more balanced grid with diversified energy infrastructure. Batteries deployed alongside chargers become part of the broader energy solution, collecting energy during low-demand periods and distributing it when needed.
"When you have battery capacity that then you're placing in nodal centers and the ability to dispense that back because the modules we're taking into the battery also are capable of distributing back to the grid," Urist said. "We can help power buildings during blackouts. We can help provide power back to the grid."
Utility companies are beginning to understand the opportunity. Orlando Utilities Commission, an early XCHARGE customer, sees promise in using battery-integrated chargers to bolster their own infrastructure.
The transition will not be instant. Policy considerations around domestic sourcing requirements, utility comfort with distributed batteries, and continued transformer shortages all present headwinds. But the fundamental logic remains: if the grid cannot keep pace with EV adoption through traditional means, alternative approaches become necessary.
"We need more capacity and we need to get capacity started now," Urist concluded. "We can solve our other problems later. But until we tackle that problem, everything else is just going to get more and more difficult."
