Tesla is set to revolutionize the electric vehicle (EV) charging landscape with its upcoming 350 kW V4 Supercharger. This new development, which was revealed in planning documents submitted by Tesla in the UK, signifies a significant leap from the current 250 kW V3 Superchargers.

“The new V4 Superchargers from Tesla are anticipated to deliver a power surge that surpasses the current 250 kilowatts (kW) provided by the V3 Superchargers.”

The Future of EV Charging

The V4 Superchargers are expected to be installed at a location in Swindon, UK, featuring 16 charging points each with a power rating of 350 kW. The site will also include 22-kW three-phase AC charging points from another manufacturer. The new V4 dispensers will be equipped with a display and a contactless bank card reader, a feature recently spotted at the Goodwood Festival of Speed in the UK.

This development confirms Tesla’s commitment to enhancing the peak output of its DC fast charging infrastructure. However, the specifics, including whether this implies an increased voltage of the chargers to support higher voltage battery packs, remain unknown.

The Potential of V4 Superchargers

The new V4 Tesla Supercharging dispensers could potentially reach a staggering 615 kW in the future. This is based on the 615 A and 1,000 V information inscribed on the back of the units in the Netherlands. However, achieving this would necessitate the installation of new 1,000 V, high-power chargers (power electronic cabinets).

Key Features of the V4 Superchargers

The V4 is set to introduce several novel features to the Tesla charging network. Here’s an updated list of changes from V3 to V4:

  1. Design/Size: The V4 stalls, in black and white, are taller than the V3 stalls and are enclosed, with a cable attached at the top.
  2. Cable Length: The V4 features a longer cable, approximately 9.5-9.8 feet (calculated from 2.9-3 meters), compared to the 6-6.5 feet in the V3 version. This is to accommodate charging inlets in different locations (non-Tesla EVs).
  3. Power Output: The V4 stalls are expected to deliver higher power than the V3 (250 kW) and support high-voltage battery systems. The maximum DC current output of the stalls/dispensers could reach up to 615 amps (A) and 1,000 volts (V), theoretically enabling a power output of 615 kW, depending on the charging cabinet and EV capability. There were unofficial reports about a 350 kW output in 2024.
  4. Charging Standard: In Europe and most of the rest of the world, the V4 will be compatible with the CCS2 charging standard. In North America and some other markets, the V4 will be equipped with the NACS charging plug, and potentially with the MagicDock (built-in CCS1 adapter) for CCS1-compatible EVs.
  5. Other Features: The V4 version may come with a contactless bank card reader and a small display, allowing usage and payment without the need for a charging network membership.
