Supercharger Version 3?

Supercharger Version 3?

Does anyone know if the Supercharger V3 (higher volts/amps) can be realized by the Model 3? Are Model 3's limited in how fast they can charge to a permanent 130/170 miles in 30 min? Is it a function of the vehicle hardware? If so can we upgrade the hardware in the future?

Here is an article discussing Supercharger V3:

If you look at the charge rate curves for the existing SC they are all initially limited to a straight line depending on battery size to prevent damage, non of the existing battery can use a higher charge rate! The only advantage is that if your the B charger, you may get the fastest charge possible. Higher charge rates may be used by new batteries perhaps over 100 kWh, say for Semi tractors etc.

Interesting point msmith55.

Once the Model 3 is embedded in the car culture - should take 12-18 months - people will not object so much to the 30 min wait to charge enough to get the next supercharger. Bathroom and coffee breaks will become a more regular part of taking long trips - that is what has happened to my wife and I over the last 5+ years of driving the Tesla pretty much everywhere.

That is when the 2nd car in the pair getting equal power is going to be assumed and people will not understand - or tolerate - a slow rate of charge when the supercharger location is almost full.

I don't understand the comment about being a B charger? Is it if you have 2 cars on one charger station the sexond charges faster?

It's a 75/25 split with the first car getting priority. That changes as the first car tapers and requires less juice.

Transformers at every supercharger stop are driving two superchargers - generally the A & B charger, but some are 1 & 2. Use to search these blogs for a table that was put out sometime in 2014.

What this means is that if you pull into a supercharger and park directly next to another Tesla you may be the second person using that paired transformer - this is why you usually see people charging one slot away from another Tesla when there are multiple cars at a stop. The second person on a transformer pair will get a reduced amount of power and thus be charging at a noticeably lower rate until the other car leaves.

With increasing power the initial person's car may not be able to use all the added power - the cars are only designed to accept so many kWh/minute - but the 2nd person in has more power to increase their kWh/min and thus gets closer to full charge in the time they are there.

If you have done much long-distance driving in a Tesla you know this, but many new drivers have to learn the hard way. That's why I am being so detailed.

@CraigW, "not every". Madison WI East Towne Mall SC was three dedicated last time I went through.

But that is just picking nits. ;-)

Also, not every stall is organized such that the A and B are adjacent. Read the signs carefully and avoid using the B if the A is occupied for the number you’re looking at. In other words, when you pull up to a Supercharger, if there are any other cars already charging, check the number on the stall you’re considering against all the other parked Teslas.

Unless you’re gonna eat at a sit down restaurant and WANT to charge more slowly. ;^)

Ok, however, I did use that supercharger in the summer of 2014 and had no problems. Of course, since I was the only one there, I didn't bother to check anything.

Thanks for the detailed information. Is this something Tesla is working to imprive so their is consistent charge rates when supercharging?

The consistent charge rates will be welcomed, but what will it take to get 350+ kw charging? Upcoming battery tech, some kind of electronic sorcery or what?
