Tesla Model 3 LR Tested At The 250 kW V3 Supercharger: Video

103


Here are some very interesting test results of a 2017 Tesla Model 3 Long Range at the latest Tesla V3 Supercharging station in Fremont, performed by Dagery.

According to the video description, the car with 2019.20.2.1 software and a warmed up battery was able to charge at 250 kW for more than 15% of SOC (between 5% and 21%), although the first attempt for some unknown reason topped out at 87 kW.

“Ambient outside temp: 65F

4:18am – 4:52am

Warm-up: 1 hour 40 mins – 100 miles

Attempt 1 failed on stall 4 (arrived with less than 1% but charger topped out at 87kW, charged to 6%). Left to launch and regen to drain battery to 2% and keep the battery warm.

Attempt 2 successful on stall 2.

2017 Model 3 LR – Software Version: 2019.20.2.1 5659e07

Total Charge Session: 34 mins”

As you can see on the chart below, the power quickly increases from 126 kW at 2% SOC to 250 kW at 5%, where it stays until 20%. At 21% and 248 kW it starts to more or less linearly decrease.

At 60% SOC the charging output is 108 kW, while at 80% just 56 kW. Power of 36 kW at 90% means that there is not much sense to charge to a high level if there is no necessity.

About Supercharging V3:

  • New architecture of chargers
  • 1 MW power cabinet, which can support up to 250 kW per car (four stalls per power cabinet)
  • no power sharing between the Superchargers (previously two stalls shared 120 kW of power, 150 kW after upgrade)
  • cuts charging time by up to 50% (when the battery is warmed up)
  • expected typical charging time to drop to around 15 minutes
  • expected to serve more than twice the number of customers per hour (than V2)
