More power can decrease the charging time, but not by that much — 5–16% and up to 3–4 minutes. The higher speeds will increase the charging rates for all Teslas using the stations, with the Model 3 Long Range and S & X with 100 kWh battery packs having the capability to gulp down power at 150kW when charging solo on V2 station pairs. Tesla will continue to validate other vehicles/battery pack combinations for further optimization as it continues to assess the max charging rates of V2 stations.
Tesla supercharging stations charge with up to 150 kW of power distributed between two cars with a maximum of 150kW per car. They take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100% on the original 85 kWh Model S. The charging stations provide high-power direct-current (DC) charging power directly to the battery, bypassing the internal charging power supply.
Base: v2019.5.15
- 100 miles — 14 minutes, 8 seconds
- 150 miles — 22 minutes, 9 seconds
- 200 miles — 32 minutes, 39 seconds
- 240 miles — 47 minutes, 6 seconds
After update: v2019.12.1.1 without On-Route Warmup
- 100 miles — 13 minutes, 15 seconds (improvement of 6.3% / 53 seconds)
- 150 miles — 19 minutes, 30 seconds (improvement of 12% / 159 seconds)
- 200 miles — 30 minutes, 0 seconds (improvement of 8.1% / 159 seconds)
- 240 miles — 44 minutes, 28 seconds (improvement of 5.6% / 158 seconds)
After update and warmup: v2019.12.1.1 with On-Route Warmup
- 100 miles — 11 minutes, 53 seconds (improvement of 15.9% / 135 seconds)
- 150 miles — 18 minutes, 32 seconds (improvement of 16.3% / 217 seconds)
- 200 miles — 29 minutes, 3 seconds (improvement of 11% / 216 seconds)
- 240 miles — 44 minutes, 23 seconds (improvement of 5.8% / 163 seconds)
As you can see, the difference is from around 5% to over 16% in time. Replenishing 240 miles of range can save you some 160 seconds at 150 kW. The peak charging power was about 142 kW, but that didn’t last long.
It’s expected that the On-Route Warmup would bring a significant difference when the battery is really cold, preventing prolonged recharging.
- 100 miles — improvement of 10.3% / 85 seconds
- 150 miles — improvement of 5.0% / 58 seconds
- 200 miles — improvement of 3.2% / 57 seconds
- 240 miles — improvement of 0.2% / 5 seconds
