Tesla opened its first full V4 Supercharger station in Redwood City, California in late September, marking the debut of 500 kW charging capability. While the milestone is US-based, it signals what European Tesla owners can expect as the V4 rollout expands.
What V4 Brings
The V4 Supercharger cabinet is a significant step up from V3. Each cabinet delivers three times the power density of its predecessor and can power up to eight stalls — double the four stalls per cabinet on V3. The peak charging rate of 500 kW is more than double the V3’s 250 kW maximum.
| Specification | V3 Supercharger | V4 Supercharger |
|---|---|---|
| Peak power per stall | 250 kW | 500 kW |
| Stalls per cabinet | 4 | 8 |
| Power density | 1x | 3x |
| Cable type | Liquid-cooled | Liquid-cooled |
There is one significant caveat: only the Cybertruck, with its 800-volt architecture, can currently draw the full 500 kW. All other Tesla models use 400-volt systems and top out well below that figure. Tesla has not announced when — or whether — future Model 3, Model Y, or Model S/X variants will support 800-volt charging.
Performance in Practice
On a Cybertruck with preconditioning active and a low starting charge, Tesla reports that V4 can recover 44% of battery capacity in 15 minutes. That translates to roughly 140 miles of range added in a typical coffee stop — closing the gap with petrol refuelling in a meaningful way.
European Outlook
Tesla’s global Supercharger network stood at 7,377 DC fast-charging stations with over 70,000 connectors as of Q2 2025, representing 18% year-over-year growth. The V4 rollout in Europe has not yet been announced, but the infrastructure already exists at scale: Tesla operates extensive Supercharger coverage across Germany, Norway, the Netherlands, France, and the UK.
When V4 stations arrive in Europe — and they will — the impact will depend heavily on whether Tesla’s next-generation European vehicles adopt 800-volt platforms. Until then, V4 stations will still benefit existing owners through improved power sharing and reduced congestion at busy locations.
Update: Tesla has since opened additional V4 Supercharger stations in the US, including on the East Coast.
