Madison, WI – E. Washington Ave. Supercharger
I have set out to make the best, most comprehensive page on the Tesla Supercharger in Madison, Wisconsin. This page will have comprehensive data on charging speed and many beautiful graphs of data! I made this post for those curious owners, EV enthusiasts and/or possible future owners.
In this post, I will be sharing my charging findings for the East Madison, Wisconsin Supercharger in the Hy-Vee parking lot which charges up to 150kW max.
Hopefully, in the coming months, we will also have a west side supercharger. This location has been mentioned on Facebook! 🙂 V3? We can only hope!
Pre-Condition the Battery
On the way to the supercharger, my battery began preheating for optimal charging due to it being 43-46F outside and I arrived at the supercharger with a 20% state of charge (SOC) after the 35.71 mi drive.
Tip: You always want to use the navigation system when you’re heading to the supercharger so the battery can be optimally conditioned and heated up before you arrive at the charger.
Tip #2: You also want to pick a stall that isn’t shared. In this situation, I used charger 2B and nobody was charging on 2A and I was able to get full charge rates.

What kind of supercharge speeds can you expect?
1 Minute| 138 kW | 562 mi/hr
I observed a peak charge rate of 141 power (kW).
Charging Voltage ranged from 2.0 (start) to up to 406V.
12 Minutes, 26 Seconds| 93 kW | 378 mi/hr
TeslaMate Charge Graph | 44.6F
|Time Stamp||Power (kW)||Voltage||SOC Change||Total SOC||Total Range|
It took 7 minutes and 43 seconds to get from 20-50% SOC (+30%), whereas it took almost 10 minutes to charge from 80-90% SOC (+10%).
It would be at least another 10-15+ minutes to get to 100% SOC.
Charge Power hung out at 136-141 kW for a short amount of time and begins to taper down (see graph above) within a couple of minutes during the initial charge.
