Chinese battery makers CATL and BYD say they have built EV batteries that charge in roughly five minutes, a speed that would rival a gasoline fill-up. The United States, meanwhile, is spending billions to expand its own fast-charging network along highways, but the chargers being installed deliver far less power than what Chinese automakers already offer consumers. That gap between battery technology and infrastructure ambition is shaping up as one of the defining tensions in the global shift to electric vehicles.
BYD’s 1 MW Flash Chargers Change the Benchmark
In March 2025, BYD launched a charging system it described as working nearly as fast as a conventional fuel stop. The company’s 1 megawatt hardware is designed for models including the Han L and Tang L, and BYD has announced plans to build thousands of charging stations to support them. At that power level, a compatible battery can absorb enough energy in about five minutes to cover several hundred miles of driving, a threshold that effectively eliminates the long wait times most EV owners still experience.
BYD is not alone. CATL, the world’s largest battery cell manufacturer, has also announced rapid-charging cells targeting the same five-minute window. Together, the two Chinese firms are setting a performance standard that no American-made EV can currently match, because the batteries and the ultra-high-power chargers needed to exploit them are being developed and deployed in tandem inside China’s domestic market. For drivers, this means the emerging Chinese experience of refueling an EV is starting to resemble the familiar gas station stop, while most other markets still treat fast charging as a lengthy pit break.
U.S. Fast-Charging Sites Grew 70 Percent, but at Lower Speeds
The American charging network is expanding quickly by its own historical standards. According to one analysis, U.S. EV fast-charging sites jumped about seventy percent in 2025, a significant acceleration after years of sluggish buildout. Yet that growth is concentrated at power levels well below what BYD and CATL are deploying. Most federally funded stations are required to deliver a minimum of 150 kilowatts per port, roughly one-seventh the output of BYD’s flash chargers. The result is that even a brand-new U.S. highway charger will take 30 to 45 minutes to add meaningful range to a typical EV, compared with the five minutes Chinese consumers are beginning to experience.
This speed gap matters because charging time is the single biggest practical objection prospective EV buyers raise. Drivers who can refuel a gasoline car in under five minutes are unlikely to accept a 40-minute stop unless they have no alternative, and the longer that gap persists, the slower U.S. EV adoption will be relative to markets where ultra-fast charging is available. The perception of inconvenience can be as important as the technical reality; if consumers believe that an EV road trip means planning meals and errands around long plug-in sessions, they may delay switching even as more stations appear on maps.
How NEVI Funding Shapes the U.S. Buildout
The federal government’s primary tool for closing the infrastructure gap is the National Electric Vehicle Infrastructure Formula Program. The U.S. Department of Transportation has issued updated guidance for NEVI that spells out eligibility requirements, technical standards, and deployment rules for stations receiving federal money. Those rules cover everything from minimum charging speeds and connector types to uptime requirements and payment systems, reflecting an effort to create a consistent national experience for drivers.
Funding levels and state-by-state allocations are detailed in a separate Federal Highway notice that lays out the apportionment of Fiscal Year 2025 Highway Infrastructure Program funds for NEVI projects. The program channels money through state transportation departments, which propose station locations along designated Alternative Fuel Corridors. In practice, that means governors and state DOTs decide which highway exits receive fast chargers first, subject to federal spacing and performance rules.
To track progress, the Department of Energy’s Alternative Fuels Data Center publishes corridor information in CSV, GeoJSON, and shapefile formats, defining criteria such as DC fast charging requirements that stations must meet for corridor inclusion. That data, powered by the National Renewable Energy Laboratory’s public stations API, enables reproducible tracking of how many charging ports exist, what power levels they support, and where they are located over time. Researchers and planners can use these datasets to identify gaps, measure utilization, and benchmark progress against policy goals.
On the ground, the program’s first stations opened in Ohio and New York under the Biden-Harris Administration, establishing a baseline for the national rollout. Pennsylvania has since moved ahead of other states: the Shapiro Administration has celebrated its twentieth NEVI site, with usage metrics such as charging sessions, estimated electric miles, and emissions reductions reported publicly. That pace suggests the federal program is producing real stations, but the total number of NEVI-funded sites open nationwide remains modest relative to the scale of the U.S. highway system and the millions of vehicles that could eventually rely on them.
Speed Versus Coverage: A Strategic Mismatch
Most coverage of the U.S. charging buildout focuses on station counts and geographic coverage, treating the problem as one of physical access. That framing misses the deeper competitive risk. China is not just building more chargers; it is building a vertically integrated ecosystem where battery chemistry, vehicle architecture, and charging hardware are designed together to deliver five-minute refueling. The U.S. approach, by contrast, treats charger deployment and battery development as separate tracks. Federal NEVI standards set a 150 kW floor for funded stations, a threshold that was ambitious when first conceived but now looks conservative next to 1 MW systems.
This creates a strategic mismatch. Automakers selling into the U.S. market have little incentive to design cars around ultra-fast charging if the public network will not support it, while charging providers have little reason to install megawatt-scale equipment if almost no vehicles can use it. The result is a kind of equilibrium at middling speeds: good enough for early adopters who can plan around 30-minute stops, but not transformative enough to erase the perceived convenience advantage of gasoline.
China’s model shows what a different equilibrium might look like. When battery suppliers like CATL and automakers like BYD coordinate closely with charging operators and local governments, they can roll out vehicles and infrastructure that are matched from day one. Drivers then experience the full benefit of each new chemistry or power level as soon as it hits the market. Over time, that can shape consumer expectations, making five-minute charging the norm rather than the exception.
Can the U.S. Close the Ultra-Fast Gap?
Bridging the gap with China will require more than adding plugs to maps. One path is to ratchet NEVI standards upward as technology matures, nudging new stations toward higher power levels while preserving backward compatibility for existing vehicles. Another is to target megawatt-class chargers at specific use cases, such as highway corridors linking major metro areas, where the benefits of five-minute charging are most visible to mainstream drivers.
At the same time, battery and vehicle developers will need clearer signals that the public network is moving in their direction. That could come from coordinated pilot projects that pair next-generation cells with a small number of high-power sites, or from procurement commitments that guarantee demand for ultra-fast hardware. Without such alignment, the U.S. risks locking in a second-tier standard just as the global benchmark shifts.
The stakes are not just about driver convenience. If Chinese firms establish a durable lead in both batteries and charging systems, they could shape technical standards and supply chains for decades, influencing what kinds of vehicles are viable and where value is captured. NEVI funding and related policies show that the U.S. is serious about building out infrastructure. The question now is whether that buildout will be fast enough, in both speed and ambition, to keep up with a world where five-minute charging is no longer a futuristic promise but an emerging reality.
