Tesla recently published an article on X detailing some of the improvements they’ve made to the Supercharging ecosystem to make it better for everyone. And boy, have they made a lot of improvements just this year - and with the recent announcement of the V4 Supercharger Cabinets capable of 500kW, it's going to get even better next year.
Since Tesla began opening its Supercharger sites to approved third parties, one key point of contention has been the charge port location. Every Tesla has its charge port on the rear left side of the vehicle, behind the driver. Superchargers before V4 rely on this location, and thus, non-Tesla vehicles with a port in a different location sometimes have to take up two stalls to charge.
Supercharger Improvements
Tesla has been making many improvements recently, even looking beyond the more powerful V4 cabinets coming in early 2025. Let’s take a look at all the work they’ve done and what’s coming up as well.
Cars Plugged In & Faster Data
One of the key updates has been to improve the overall accuracy of stall availability - the backend system refreshes fairly quickly, providing an accurate stall count - which helps to improve navigation and trip planner improvements too. Tesla announced that it’s now able to detect what type of EV is plugged in so that it can better assess charging estimates and determine if a vehicle may be taking up two stalls and automatically takes this into account when routing vehicles.
Max de Zegher, Director of Supercharging North America, mentioned on X that the stall availability now refreshes every 15 seconds, and with mapped Supercharger site layouts, Tesla can see which stalls are available.
The updated stall availability algorithm is a big improvement, with nearby refresh rates now every ~15 seconds. We know car types plugging in and mapped out Supercharger site layouts, to know which stall is not available at short cable sites. Your Tesla's touchscreen now shows… https://t.co/5PF7wruNhQ

V4 Chargers to Outnumber V2 & V3 Combined
As part of the V4 Supercharger stall upgrade, Tesla has been deploying stalls with longer cables and stalls with built-in adapters for CCS vehicles. These new longer cables mean that Tesla’s Supercharger sites can serve more vehicle charge port layouts without having to block a stall. That increases site availability, and Tesla expects to have more V4 charging stalls in the next 18 months than it has V2 and V3 stalls today. Some of these will be due to new locations, but Tesla is also updating current Supercharger locations.
Modifying Current Superchargers
Tesla has also been working to modify its site planning and layouts—both sites that are already built and sites still in planning. Over 1,500 sites have been altered to better serve drivers by widening the parking spaces, ensuring that drivers never have to use more than two ports to charge.
Pull-Through Trailer Chargers
Another big one is the deployment of pull-through Supercharger Trailer spots. These spots mean you don’t need to unhitch your trailer from your vehicle before supercharging, which is excellent for vehicles like the Cybertruck when you’re towing a trailer and need to charge up before continuing on your trip. Tesla update 2024.44 also adds the ability to see which Superchargers have trailer-friendly charging stalls.
Standardized Port Location
The last - but one of the most important - things that Tesla is doing is encouraging manufacturers to move their charge ports to either the rear left or front right of vehicles, thereby helping to improve compatibility with Supercharger sites. Manufacturers have already taken steps to standardize in Europe, but these changes really haven’t rolled out globally yet. Rivian recently announced that the charge port for their upcoming R2 and R3 vehicles will be in the rear driver’s side, matching Tesla’s port location.
We hope to see more improvements in this space, especially as NACS becomes the de facto standard in North America.
