With the public opening of the first V3 Supercharger Station in Fremont, we can now start collecting charge session data to ferret out the ideal charging profiles for the different Model 3 battery configurations. When firmware 2019.12.1.x was released, which allowed 150 kW Supercharging on the updated V2 stations, we were able to determine those profiles in this thread: 150kW Supercharging for Model 3
From early reports, 2019.20.1 will allow 200+ kW power levels at Fremont and later V3 stations, such as Hawthorne, once they come online. This data will allow us to verify Tesla's charging speed claims, but also help us understand the nuances to optimise charge sessions for fast, efficient travel. This is relevant because the battery chemistry as implemented in the Model 3 has a significant taper from 250 kW. The charging rates are also heavily dependent on battery temperature, where 40°C [104°F] appears to be the ideal charging temperature. I expect the fastest charge rates will only be possible under select conditions and we should understand the constraints.
The key data to collect is charging power (kW) and indicated State of Charge (%). It would also be helpful to know the duration of the charge session, if not intermediate times, as well as how hard the car was driven and if On-Route Battery Warmup was used. Of course it is also important to tell us what car configuration you have as the profiles will be different for SR, SR+, MR and LR packs. Send us what you see!
