Mobile supercharger for track days?
- Thread starter bryanheitman
- Start date
Uh, 240v isn't supercharging. It pulls a LOT more power. (AC charging pulls around 11kW for the model 3. Supercharging pulls up to 250 kW. The biggest generator I can find listed at Home Depot is 19kW, which isn't close to enough to power a supercharger ... if it's even possible to run on only 240V)
No ideas other than keep pushing Tesla to put chargers at tracks / pushing tracks to install chargers.

Does the track have three phase available?

Be the fastest diesel car at the track...
(Edit: $43k for the generator, 2k for a trailer, $15-20k for the CHAdeMO charger)

I couldnt even imagine someone pulling up to a track with a trailer hauling a charger with them. If anyone in a tesla did that, it would make national news and be in every car blog in the country (and several outside the country) and I am not even kidding, lol.

Tesla does have a portable supercharger using megapacks.
I'm unaware of it being for sale to anyone but I suppose you could ask.

If there is spare space somewhere at the track in your downtime, you could have some coal-roller drag you around the area for a bit, with high regen. Some soft shackles and a strong dynamic rope and it should be pretty safe through the tow hook (also do NOT use a standard tow hitch ball on the truck, which is not appropriate for any shock loads - use appropriate, safe, equipment). Just don’t run over the rope (I’ve learned my lesson with a different EV). Generally running over the rope should not be a problem if you are using max regen, though changing directions can be tricky. I ran over the rope because the EV had no power brakes any more since it was completely dead, and it was not regenerating either (all very difficult to deal with at night).
So you just need a friend with a truck (or really any vehicle able to tow the load) at the track and you should be good.
I’ve never tried this, but I assume it would work fine. Not sure if there are any problems with this idea. Don’t blame me for the suggestion in any case... In theory it should be way faster than L2, and potentially as fast as a Supercharger at least at higher SoCs. Running over the rope would lead to major damage to your front bumper (I was lucky in my case since the EV had a very short bumper which simply flexed a little).
Not technically more efficient than driving across town, I suppose. Might be more convenient though!

Yes. I had not seen this.
Really probably the best option. The times aren’t clear here, but it appears he added a couple % in just a few minutes of towing. So probably something like 50-75kW charge rate. Not bad and of course going a bit faster would increase that (up to the limit of regen which will be dynamically adjusted by the car, just as it does for Supercharging). Probably 30 minutes of dragging, maybe an hour for a more full day, would be all you’d need for the day.
I remember seeing this before here on the forum. This is becoming very common at a lot of race tracks around the country. I would say talk with the management of the track you're going to and suggest it.
Here are some previous threads about this:
Track junkies, need some info
Hey guys, I am about to order a Performance Model 3 to replace my track car. I think it is time to move away from oil and get a more practical car at the same time. Anyway I would like to get some information for this car as a track vehicle, please let me know what I should be looking for and...

Who do you race with in SoCal?
I'm looking to take my Tesla out for some AutoX and maybe even to a big track. Anyone Track theirs in SoCal and have recommended tracks (recommended because it was easy to recharge between sessions) or groups you ran with? I used to run with the PCA and POC allot when I had my Boxster.

Taking the Model S on a track
Just to preface: I've never raced before. My last car was a Prius and I drove like a grandma. That being said, with my new P85, I'm looking to push it a bit and am curious about circuits/racetracks around the SF bay area that I can take it to. Moreover, I'm interested in whether there are...
