Tesla launches first full V4 Supercharger station offering 500 kW capacity

First 500kW supercharger now live

Tesla says its first ‘true’ V4 Supercharger site capable of up to 500 kW per stall is now live in Redwood City, California, marking a major step up in peak charging capability. For now, Cybertruck is the only Tesla built on an 800-V system, so it’s the sole model that can tap the new 500-kW peak.

This new station utilizes the advanced V4 Supercharger cabinet, which is designed to be set up significantly faster than the older models. Tesla’s V4 cabinet is rated at three times the power density of the prior generation and can power up to eight stalls per cabinet (versus four on V3), enabling faster and denser rollouts.

Cybertruck charging times explained

Even with the 500kW peak from the new V4 hardware, the time saved for a full charge is only a slight improvement. Tesla Cybertruck lead engineer Wes Morrill says the Cybertruck can recover up to 44% of its charge in 15 minutes on a V4 stall when preconditioned and starting with a low charge.

While that is fast, this 15-minute charge is only roughly 13% faster than the speed achieved at the older 250kW V3 Supercharging stations. The high 500kW rate is only briefly available, as the 325kW speed was already possible at some V3.5 stations.

Short peak speeds limit time savings

Because the peak power is only available for a short time, the total charging session does not shorten significantly for most drivers. Early tests on a true 500-kW V4 cabinet reveal brief bursts near the peak and modest total-session time savings compared to 250–325 kW sites.

These limitations show that sustained power is key, as only about three minutes are saved compared to the maximum rate achieved at the 325kW V3.5 Superchargers. To sustain high charging rates past 44% state of charge, Tesla must refine the battery software.

V4 cabinet supports more charging stalls

The most significant benefit of the V4 system is not its peak speed, but rather how it will help Tesla expand its network efficiently nationwide. The new V4 design enables the cabinet to support twice the number of charging stalls as the previous version.

This greater efficiency is due to density. Each V4 cabinet can dynamically feed up to eight stalls (versus four on V3), while enabling 500-kW peaks for light-duty EVs and 1.2-MW support for semi-infrastructure. This increased density simplifies site construction and lowers the hardware costs for expansion.

Cybertruck max intake at third-party stations

The high 500kW charging power is strictly restricted for use only with Tesla’s latest V4 Supercharger hardware. When the Cybertruck plugs into any non-Tesla third-party charger, the truck’s internal software limits the maximum power it will accept.

This self-imposed power limit means the Cybertruck instructs third-party chargers that its power limit, or EV Maximum Power Limit, is 326kW. This restriction is based on the current limits of the battery’s capability, which uses an 800-volt high-speed architecture.

China requires mechanical handle for safety

Beyond the technical limits of power and voltage, Tesla faces significant design challenges in overseas markets, such as China.

China’s MIIT has released a draft for public comment, requiring external handles with mechanical releases that operate without power, as well as interior mechanical backups that are clearly visible and located within 300 mm of the door edge. This ensures first responders can open the door without needing electrical power during an emergency.

Tesla must redesign its door systems

The new Chinese rules create a significant obstacle for Tesla, whose current flush door handles are mainly electronic. Tesla’s Head of Design, Franz von Holzhausen, confirmed they are working on new handle designs to meet these safety requirements.

The issue is a technical failure to comply. Older Model 3s lacked a rear mechanical release cable, leaving them vulnerable in emergency situations. Newer models added a hidden cable, but this is not considered visible enough to meet the clear 300mm visibility rule in the latest Chinese draft.

Supercharger network grew to 70,000 connectors

The expansion of the Supercharger network is continuing at a fast pace, despite the company facing design challenges. As of the second quarter of 2025, Tesla reported having 7,377 DC fast-charging stations globally, a 14% increase from the previous year.

This growth extends to the connectors. The Supercharging network now has over 70,000 connectors worldwide, representing an 18% year-over-year growth rate. In Q2 2025, the network delivered 1.6 terawatt-hours (TWh) of energy, a 26% increase in total energy delivered.

NACS is now the North American standard

This massive, growing network is why Tesla’s charging plug, the North American Charging Standard (NACS), is becoming the industry norm. Twelve automakers have announced they will integrate NACS ports into their new vehicles starting in 2025.

The shift is already happening for customers. Starting in 2025, major brands such as General Motors, Ford, and Kia are beginning to incorporate the NACS port into their future electric models. Non-Tesla owners can now access over 23,500 Superchargers using an adapter.

V4 cabinets support future power needs

Tesla is future-proofing its network to support all these new vehicles using the NACS plug, which is why the V4 cabinet is so important. These cabinets can handle high voltages ranging from 400 volts to 1,000 volts, necessary for all next-generation electric vehicles.

The potential power is massive. The V4 is designed to deliver a high charging rate of 0.5 MW (500 kW) for passenger vehicles, such as the Cybertruck. The cabinet is also built to support a future 1.2 MW rate, which is the high design target speed for the heavy-duty Tesla Semi truck.

FSD expansion in European Union

As the charging network expands, Tesla is also expanding its next major technology, self-driving software, into new areas. The Full Self-Driving (FSD) Beta software is beginning trials in select European countries under special government permits.

FSD in Europe: status remains limited. Tesla continues to seek broader regulatory clearance in Europe; reporting indicates ongoing hurdles, and no widespread public ‘Beta’ program has been formally approved by national authorities at this time.

Cybertruck performance and battery specs

The vehicle that shows the peak of Tesla’s hardware and software power is the Cybertruck, available in high-performance versions. The Tri-Motor version generates 834 horsepower and can launch from 0 to 60 mph in only 2.6 seconds.

Power comes from a big battery. Both the Tri-Motor and All-Wheel Drive Cybertruck models use a large battery pack with a capacity of 123.0 kWh. The truck is also physically large, measuring a total length of 223.7 inches and standing 70.6 inches tall.

Cybertruck truck capability and onboard power

The Cybertruck is designed with strong utility specifications, matching its incredible speed with real-world capability. The truck has a maximum towing capacity of 11,000 pounds and a high payload capacity of 2,500 pounds in its stainless steel bed.

It acts as its own power station. The bed, or vault, has an onboard power system featuring a total of five electrical outlets for tools and devices. This includes one 240-volt outlet that can charge another electric car, adding up to 30 miles of range per hour.

Supercharger network traffic is heavily used

With all these powerful and capable vehicles on the road, the Supercharger network is becoming extremely busy. In the second quarter of 2025, the network logged a record 45 million charging sessions, representing a 26% increase in usage from the previous year.

Usage rates are high for each spot. Globally, each Supercharger stall was used for about seven charging sessions per day in Q2 2025. In North America, usage is even higher, with data reporting the average is closer to 10 sessions per stall per day in key states.

Cybertruck range and ground clearance

The Cybertruck is designed to travel long distances and navigate rough terrain, addressing the needs of truck owners. The All-Wheel Drive version achieves an estimated range of 325 miles, and the Tri-Motor version has an estimated range of 320 miles per charge.

Off-road ability is maximized. The truck is equipped with adaptive air suspension that provides significant height adjustment. This advanced suspension enables a maximum ground clearance of 16 inches when the car is in its special “Extract Mode” setting.

The future of Tesla’s global design strategy

Ultimately, all these global challenges, from charging standards to regulatory demands, point toward a unified design future. The need to change the door handles for China may force Tesla to settle on one simple, global design for all models.

This will mean a design change. The era of the purely electronic, flush door handle that Tesla popularized is likely coming to an end due to these strict safety rules. The company’s goal is to achieve a single global design that meets the new 300mm visibility rule across all continents.
