Key Points
- ⚡ Tesla’s V4 Superchargers have been confirmed to have a charging speed of 350 kilowatts.
- 🚗 The V4 Superchargers were previously unveiled in Europe, but official specifications were not disclosed until now.
- 🔌 The charging power of 350 kW is available for cars that support it, with the Tesla Cybertruck expected to be the first to feature an 800v architecture enabling ultra-fast charging speeds.
- 📄 A Development Proposal submitted by Enzygo confirms the 350 kW power for the V4 Superchargers.
Tesla has finally confirmed a crucial detail about its V4 Superchargers, putting an end to speculation about their charging speeds. The company has officially stated that these chargers are indeed capable of delivering a charging speed of 350 kilowatts.
In recent months, Tesla has been unveiling the V4 Superchargers at various locations in Europe. However, specific details about the new chargers were scarce, as the company had not publicly disclosed the explicit specifications for the new stalls.
Upon the installation of the first units in Harderwijk, the Netherlands, Teslarati reached out to the first users and obtained exclusive information about the V4 Superchargers. According to individuals on the ground in the Netherlands, the V4 stalls had experienced a significant 31 percent amperage increase, reaching 615 A, and the cable length was also extended, suggesting Tesla’s readiness to accommodate other automakers utilizing these charging stations.
However, a new Development Proposal submitted by Enzygo (via u/RealPokePOP on r/Tesla Motors) shows Tesla has officially confirmed the V4 Superchargers to have a power of 350 kW, as many cars were still topping out at 250 kW.
The proposal says:
“This combined Planning Statement and Design and Access Statement supports a planning application made by Tesla Motors Ltd for the development of 36no. EV charging units (16no. ultra-rapid V4 superchargers (350kw) & 20no. ChargePoint 6000 series EV chargers (22kw)), associated equipment cabinets, substation and associated electrical infrastructure. All charging units are universal and can be used by any EV user.”
This does not mean that every EV that charges with the V4 Superchargers will get that power. The vehicle itself must support that, and it is the reason Tesla has said that the Cybertruck will be the first car to feature an 800v architecture, which would enable these ultra-fast charging speeds.
Current 400-volt architectures will not support anything higher than roughly 250 kW, at least for now.
Other automakers have planned to bring 800v architectures to their EVs.
