Tesla may also be "selling" the charge rate on model 3 right now, and slow it down in the future too... preserve battery.
If it would continue at that rate, that would be great, but it drops off quickly.
No, it means 125 miles in 15 minutes. If you look at the graph it is non-linear (the charge rate in mph - or kW - decreases over time)
That's neat! Easily beats how my P85 charges.
If you want to have data like this automatically collected to look at later, I'm going to shamelessly promote the App I made called Nikola that does that. Originally made it for myself, but decided to publish it after people started asking for it.
Available to look at here: Nikola for Tesla on the App Store
Can confirm the app works with the Model 3. The fleet is over 10% Model 3s at this point.
