Power parking: The challenges of EV charging infrastructure

A conventional gas station is a machine for short stops. A driver pulls in, occupies a dispenser for a few minutes, pays, may enter the store and leaves. The canopy, pump island, underground tank, forecourt lane and convenience-store entrance all assume quick turnover.
That system will not suit every vehicle over the next two decades. Some vehicles will still need gasoline or diesel, while others will need 150 kW to 350 kW of DC fast charging. Fleet vehicles may need scheduled charging windows, staging space and separate circulation, and a smaller number of sites may handle hydrogen or battery exchange when equipment costs, vehicle design and daily utilization align.
The mismatch starts with the baseline; petroleum still supplied about 89% of U.S. transportation energy use in 2025, and 122,620 U.S. convenience stores sold motor fuels at the end of that year. That footprint will not be rebuilt from scratch, but it will be sorted. Each site will have to prove which vehicles it can move through without wasting land, power or capital.
Vehicle fleets keep pumps in use
Fueling infrastructure follows vehicles actually in use, not press releases about future models, exciting and seemingly imminent as they may be. The U.S. had 297.5 million registered motor vehicles in 2024, and the average U.S. light vehicle was 12.8 years old in 2025, which helps explain why fuel demand changes more slowly than the showroom mix.
New-vehicle sales already show a split market. Hybrids, plug-in hybrids and battery-electric vehicles (BEVs) together accounted for about 22% of U.S. light-duty vehicle sales in 2025, and electric vehicles (EVs) accounted for 2% of registered light-duty vehicles in 2024. The distance between those figures leaves room for EV growth while still leaving a large number of gasoline and diesel vehicles on the road.
Hybrids complicate the story further because they cut gasoline use per mile, but they still depend on gasoline stations. Recent declines in gasoline consumption have been tied in part to higher fleet fuel economy and rising hybrid sales, pointing to lower, less uniform gasoline throughput rather than the quick disappearance of pumps.
At the same time, diesel has its own clock. Truck travel is projected to keep growing through midcentury, according to vehicle-miles-traveled forecasts. Battery-electric trucks can serve parts of the fleet, especially on routes that return to base, but long-distance, high-payload and rural work will keep diesel useful where range, charging time or grid capacity does not yet meet the job.
EV charging not equal to fuel refills
A gasoline vehicle almost always needs access to a public or commercial fueling station, but an EV does not. Most light-duty EV energy flows into vehicles while they are parked for hours: at home, at work, at a depot, at a multifamily property or at a slower public charger.
That changes the role of the forecourt; a 2030 charging scenario estimates that Level 1 and Level 2 charging would supply about 80% of EV charging, while DC fast charging would supply about 20%. Public fast charging remains necessary for long-distance travel, ride-hailing, drivers without home charging and high-utilization vehicles, but it is not the daily equivalent of the gasoline pump for most drivers.
The customer stop also changes with it. DC fast charging commonly takes 20 minutes to one hour to reach 80% charge; a charging stall stays occupied far longer than a pump lane. That makes fast charging a parking, queuing and uptime problem before it becomes a retail opportunity.
The most useful public fast-charging sites will be those that can accommodate longer dwell times without blocking circulation and keep drivers on site without making the stop feel like waiting beside utility equipment.
Fast charging transforms sites into electrical projects
DC fast charging adds a power project to a retail site. Public DC fast-charger equipment is estimated at about $38,000 to $90,000 per connector, with installation often ranging from $20,000 to $60,000 per connector. Trenching, switchgear, transformer capacity, utility work and traffic-flow changes push costs even higher.
That means that the schedule can hurt before the invoice does. High-powered EV chargers can take up to two years to connect to the grid, and energization delays often come from permitting, easements, impact studies, engineering work and utility resource limits. A high-traffic parcel with weak electrical capacity may convert more slowly than a plainer site near available distribution infrastructure.
Phased charger deployment, load management, onsite battery storage and flexible interconnection can reduce peak demand and manage demand charges. They do not, however, erase the need for grid capacity, but instead, they change how much power a site can use economically.
Reliability also moves from a maintenance issue to a design requirement. For example, federal corridor chargers funded under NEVI must meet more than 97% uptime, but uptime does not capture every failed session. Payment faults, communication failures and first-attempt charging errors can still strand a driver at an apparently available charger, as charging-reliability research notes. Thus, a charging site succeeds only when the vehicle actually takes energy.
Retail economics will decide how many stations should make that investment. Fuel accounted for 65% of convenience-store sales dollars in 2025 but only 38.8% of gross-profit dollars. A longer charging dwell time can help boost foodservice and merchandise sales. It cannot rescue a site with low charger use, weak uptime, unfavorable tariffs or poor circulation.
Fleets will produce specialized sites
Fleet sites have one advantage that ordinary retail sites often lack: predictable demand. A delivery fleet, rental fleet, municipal shop or drayage operator can schedule charging, assign bays and tie energy use to inspection, cleaning, maintenance and dispatch. The site becomes part of the operating system.
Heavy-duty charging raises the scale because, for example, a Class 8 electric semitruck may need at least 350 kW from a connector to charge in a matter of hours. A site serving several heavy-duty trucks quickly may need 20 MW or more. That affects substation planning, turning radii, staging, cable management, charger cooling and utility tariffs.
Freight planning follows the same split, as reflected in the national zero-emission freight strategy, which focuses on charging and hydrogen fueling for medium- and heavy-duty vehicles along freight corridors and near ports. Some corridor sites may become mixed-energy logistics nodes while others will remain diesel stops and service facilities because their users, routes and local grid conditions point that way.
Hydrogen and swapping
Hydrogen and battery swapping fit best where a site operator controls vehicles, routes or fuel demand. Hydrogen can make sense in buses, material handling, ports, fleet depots and some heavy-duty corridors, but the U.S. light-duty retail case remains thin at best. The U.S. had 54 open retail hydrogen refueling stations in 2024, mostly in California, and California’s latest hydrogen review found high prices, low demand and slower-than-projected FCEV growth in the leading U.S. light-duty hydrogen market.
Battery swapping shows the same boundary, best illustrated by China. China has extensive swap networks, including thousands of car battery-swap stations and truck-swap sites. The model works best when vehicles are identical, routes are defined and battery ownership is managed centrally, but those conditions do not describe the general U.S. retail market. Controlled projects such as the Stellantis-Ample battery-swapping partnership point to a more credible use case; these technologies may matter in depots and corridors, but they do not turn every fuel retailer into a universal energy hub as is often imagined.
The station becomes specific
Over the next 10 to 20 years, fueling stations are more likely to diverge than converge. Liquid-fuel sites will remain necessary for the long-lived internal-combustion and hybrid fleets, rural drivers, many commercial users and parts of the freight sector. Public fast-charging sites will grow where corridor travel, urban charging gaps and high-utilization vehicles justify power upgrades, longer dwell times and tighter maintenance standards. Fleet depots and freight corridors will carry the heaviest electrical loads, and hydrogen and battery swapping will be viable only where utilization, vehicle control and standardization justify the cost.
The strongest sites will be those that choose their work precisely: which vehicles they serve, how long those vehicles stay, how much power or liquid fuel they need, and what circulation pattern prevents the site from clogging. The future fueling station is less a universal stop than a filtered one; it has to know its vehicles first.

Okay, has someone calculated where and how this needed incrreasing energy for electric vehicles is produced and how this energy is brought to stations considering the virtual increase of this kind of vehicles. Especially adding the battery production thematic which also needs quite big amount of energy. A kind of energy bilance country-wide would be useful here included the different scenarios of amount of vehicles, needed battery production , needed energy to keep this running comparing to the actual power output from energy producers and needed loading capacity of (how many) stations. Thank You!

Thanks for commenting! It's an important, complex question - but this article was focusing on one part of the EV infrastructure. There are broader studies out there that are interesting to review if you want to. Look up IEA, ERCOT and similar.
