Tesla’s New ‘Folding’ V4 Superchargers Deploy 2X Faster With 500kW Power

Tesla has officially introduced its new Folding Unit (FU) Superchargers, a radical redesign of its charging infrastructure aimed at doubling deployment speed while slashing costs by more than 20 per cent. The new system pairs Tesla’s high-power V4 cabinets with a modular, transport-friendly design that simplifies the entire installation process.

Max de Zegher, Tesla’s Director of Charging for North America, noted that the majority of the savings come from reduced civil, electrical, and logistics expenses. The pre-assembled units eliminate the need for DC busbar connections on-site and, most notably, do not require a Tesla service technician to be present for commissioning.

The hardware specifications are a significant jump from previous generations:

• V4 Cabinets: Capable of delivering up to 500kW for passenger vehicles (like the Cybertruck) and 1.2MW for the Tesla Semi.
• Higher Density: Each unit contains eight charging posts, and Tesla can now ship 16 stalls per truck—up from the previous limit of 12.
• Flexible Layouts: The units can be deployed in “folded” back-to-back configurations or “unfolded” into a traditional side-by-side row.

The timing of the announcement coincides with a major manufacturing shift at Tesla’s Gigafactory New York. The facility recently produced its final V3 cabinet, ending a seven-year run to focus 100 per cent on the more powerful V4 hardware.

By decoupling site commissioning from its own internal service capacity, Tesla is removing a major bottleneck in its goal of achieving universal EV adoption. De Zegher added that while this is only the first version of the folding units, the company expects to have a third revision ready as early as next quarter.

As of the first quarter of 2026, Tesla has expanded its global network to over 65,000 Superchargers across more than 6,200 stations, marking a significant increase in charging density since opening the network to other brands.
