EVWire brief: Tesla just shared a peek behind the curtain of their Supercharging arm and its utilization data. We learned both their historical performance, and got some additional details on how Supercharging utilization differs per region!
For context, Tesla has now deployed over 70,000 Superchargers across the planet in over 7,400 locations.
Now, they’ve shared the graph below, which shows their average global utilization, with the Sessions per Stall per Day (SSD) steadily growing to over 8 per day, about doubling since mid-2021.

I looked it up and Tesla had "just" 26,900 Superchargers in mid-2021. So we now know that they've nearly 3x'd their charger count while doubling their utilization within the last 4 years.
Given that Tesla also oversizes their infrastructure somewhat (e.g how they build to also count for holiday surges or to avoid no coverage areas across geos), it's especially significant they are still able to win in utilization at scale.
The Director - Charging @ Tesla, Max de Zegher, was kind enough to answer my question on how the utilization for Tesla Superchargers differs across the continents:
"Exactly. Our mission is to get more EVs on the road, so we have to be careful on not pushing utilization too high and keeping charging dependable. Customers come first, utilization optimization second through disciplined network planning.
As of June 2025:
- North America: 10 SSD
- Europe: 7 SSD
- APAC (excl. China): 5.3 SSD"
This is fascinating to learn, since there’s several factors at once that go into the lower or higher utilization per region for Tesla.
Max also commented on the data on waiters we see on the graph:
