Tesla is entering a new era of electric vehicle infrastructure as the company officially transitions production to its next-generation charging hardware. On March 16, Tesla Charging confirmed that its Buffalo, New York, facility has completed production of its final V3 Supercharger cabinet.
The move marks the conclusion of a massive hardware cycle that saw more than 15,000 V3 units manufactured over the past seven years. These cabinets have been the backbone of the Supercharger network, known for delivering up to 250kW of power to Tesla owners globally.
Now, the company is shifting its focus entirely to the V4 cabinet line. Max de Zegher, a director for Tesla Charging, highlighted the milestone by stating, “All in on V4 cabinets! So cool to see how far we’ve come from V1. The brand new V4 cabinet line at Giga New York is automotive-grade and spooling up for charging ubiquity around the world.”
The V4 cabinets represent a significant technical upgrade over the outgoing V3 model. While the V3 units were capped at 250kW, the V4 architecture is designed to support much higher power outputs and higher-voltage vehicle architectures. This is critical as Tesla opens its network to other manufacturers and prepares for larger vehicles like the Cybertruck.
Supercharger cabinets are the heavy-duty power electronics that sit behind the scenes, away from the sleek pedestals drivers plug into. They convert utility power into the high-speed DC current used to charge batteries. By moving to an automotive-grade V4 design, Tesla aims to improve reliability and efficiency as it scales the network toward global ubiquity.
Tesla Charging noted the transition is already in full swing, stating that “Gigafactory New York built their last V3 Supercharger cabinet, marking the end to 15k+ V3 cabinets over 7 years. V4 cabinet line is ramping up!”
