150 kW Tesla Supercharger V2: How Much Faster Is It?

The most recent update of V2 Superchargers to 150 kW output and a new On-Route Warmup feature increases the pace of fast charging, but by how much exactly?

According to the test performed by Alex Venz on the Tesla Model 3 Performance, the difference from increasing peak output from 120 kW to 150 kW (+25%) is rather small, especially when charging to a high SOC.

Tesla Model 3 On Supercharger V3: Here Are The Charging Specs

The test consists of three scenarios of charging from about 10% SOC to 90% SOC, at similar temperatures and at the same charger:

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 (close to 220 seconds if you end earlier and used On-Route Warmup feature). 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. Using the feature just like in the video, the difference between the two scenarios (with and without On-Route Warmup) is worth maybe a minute:

• 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
