Tesla has wrapped production of its V3 Supercharger cabinets after a seven-year manufacturing run at Gigafactory New York. The facility produced more than 15k V3 cabinets during that period, but the company is now transitioning entirely to V4 cabinet production. According to Tesla Charging’s official account on X, V4 cabinet line is currently ramping up at the New York facility.
V4 Supercharger system represents a substantial improvement over its predecessor. Each V4 cabinet can power eight charging stalls, double the capacity of V3 cabinets, which should accelerate deployment timelines and reduce the physical footprint required for new sites. Tesla claims the V4 is the cheapest Supercharger to deploy yet, coming in under $40,000 per stall.
Performance specifications have also improved considerably. While Tesla’s current vehicle lineup will continue receiving the same 250kW charge rates they experience on V3 hardware, enough to add 200 miles of range in 15 minutes, V4 system supports peak charging speeds up to 500kW for passenger vehicles. Cabinets can handle 1.2MW for the Tesla Semi and work with vehicle architectures ranging from 400V to 1,000V, first SemiCharger V4 Superchargers set for Carson, CA, providing compatibility with a wider range of electric vehicles.
Tesla’s engineering team redesigned the power electronics for the V4 system, aiming for what the company calls “the most reliable on the planet.” New hardware achieves three times the power density of previous generations, enabling higher throughput while reducing costs. Combined with the increased number of stalls per cabinet, these improvements should allow Tesla to bring more charging sites online faster than before.
V4 stalls themselves feature cables that are three feet longer than V3 units, addressing a common complaint from drivers of non-Tesla vehicles who sometimes struggle to reach charging ports located in different positions.
Tesla is leveraging its charging infrastructure experience through Supercharger for Business, a program that provides third-party locations with Tesla’s hardware, software, and service. The company noted that in 2025, its network of more than 75k stalls delivered 6.7 terawatt-hours of energy, surpassing the combined output of all other fast chargers outside China.
Sites operated through the business program receive the same visibility in the Tesla app and operational oversight as company-owned locations. Tesla positions this as a full-service solution with dedicated support and tailored configurations for each business location.
Transition to V4 cabinets signals Tesla’s confidence in the new technology and its ability to scale production rapidly. As Gigafactory New York ramps up V4 manufacturing, the company appears ready to supercharge its infrastructure expansion with hardware that’s cheaper, faster to deploy, and more capable than what came before.
