Finding a free stall at a busy Supercharger is about to get more predictable for drivers who do not own a Tesla. The company has begun rolling out forecasted Supercharger availability inside Google Maps, extending a feature that until now only showed how many stalls were free at that exact moment.
What the feature does
Live availability tells you the present; forecasting tells you the future. Instead of only displaying that a site has, say, 11 of 12 stalls open right now, Google Maps will also estimate how many are likely to be free by the time you actually arrive — predicting, for example, that 8 of 12 will be available when you pull in. The forecast is built from a mix of historical usage patterns at each site and real-time data from the Tesla fleet, so it reflects both the usual rhythm of a charger and current conditions on the road.
The roll-out is global and aimed at eligible non-Tesla EVs — vehicles that ship with Google Maps built into the infotainment system through Android Automotive. That covers a growing list of brands beyond Tesla, and dovetails with the wider opening of the Supercharger network to other manufacturers under NACS in North America and CCS in Europe.
The catch: you have to share data
The forecast is not entirely free. To see predicted availability, non-Tesla owners must opt in within settings to share their trip and usage data with Tesla. Decline, and Google Maps falls back to showing only live stall counts. It is a fair trade in principle — accurate forecasting needs route and arrival-time data to work — but it is worth knowing the toggle exists before the feature appears greyed out.
Why it matters for European drivers
Google's built-in maps are increasingly common in cars sold across Europe, including models from Polestar, Volvo, Renault and Ford that use Android Automotive. As more of those vehicles gain access to Tesla's Superchargers, congestion forecasting removes one of the bigger frustrations of charging on a long trip: arriving at a site to find every stall taken. The capability builds on the live Supercharger availability Google Maps added in late 2025, and continues Tesla's slow transformation of its once Tesla-only network into general EV infrastructure.
There is a practical upside for everyone, not just the driver staring at the map. Better-distributed arrivals mean fewer cars converging on the same busy site at the same time, which eases queues and keeps stalls turning over — a small but real benefit for a network that has had to absorb a wave of non-Tesla traffic since it began opening up. The more drivers who plan around predicted congestion rather than blindly routing to the nearest charger, the smoother the whole network runs.
For now the feature is rolling out gradually, so not every eligible vehicle will see it immediately, and availability can vary by region as the back-end data coverage expands. But the direction is clear: route planning for non-Tesla EVs is steadily catching up with what Tesla drivers have had on the in-car map for years.
