SuperCharger Launch

[dpeilow]

The type label says 210 A max continuous at 410 V output, so that's 86100 W.

The type label says 210 A max continuous at 410 V output, so that's 86100 W.

Yes, this is slightly odd as we've seen cars at other sites charging >210A, and also 410V is the max (at which charging will be a much slower rate), with the typical being more like 375V. 375V @ 210A is a bit under 80kW.

This particular site is limited to a single car, so is probably a candidate for the 9-way rather than 12-way stacks that were mentioned as being options. I first thought this was low for the expected 90kW, but we are talking output power not input and need to account for efficiency. Tesla quote a charger efficiency (for the car) of 92% so 90kW * 92% = 82.8kW which fits with these figures.

BTW, driving at 80 mph would still be a bit faster, including the additional charging time, as long as the charging power is 51 kW or more. As far as I can tell based on some tables matching the Model S graph.

Driving at 70 mph is still faster (than driving slower), charging time included, for charging powers above 45 kW.

However, of course, the energy consumed always increases with higher speed.

Since the charge rate is FAR from linear the distances in-between charges will make a big difference. When the S begins racing we will learn real world distance and charge optimisiation.

When the S begins racing we will learn real world distance and charge optimization.

When the S begins racing, I'd hope we'd see those promised fast battery swaps. Supercharging would still be needed for the swapped out pack.

Hmm, are the Superchargers slower than advertised? Dr. Computer's experience is:

1) Harris Ranch: 50% to 75% SOC in about 50 minutes
2) Fort Tejon: 25% to 75% SOC in about 45 minutes

At Fort Tejon, I would have thought the 50% charge (from 25% to 75%) would have taken only the promised 30 minutes, not 45. Does this mean we only get the 50% charge in 30 minutes when starting with an almost completely discharged car? A 50% increase in time to charge (30 minutes to 45 minutes) is not insignificant.

 

[napabill]

As high-tech as these SC's are, I would think that data can or is collected on each charge. That would ultimately give the real world averages on charging from all SOC's. One can only hope it will be made available.

 

[Norbert]

First I thought the one at Harris Ranch might be limited by available power. However apparently it started charging at 300 mph. So the numbers seem inconsistent. I wouldn't expect it to simply stop at 75%, but maybe that's what it did. (EDIT: It seems in Gilroy it went to about 88%).

A possible explanation might be that when coming to Gilroy, on 101, the battery temperature wasn't as high, but later, after driving for a long time on Hwy 5, it had a higher temperature, at which it limits to 75%. Probably not exactly that, but perhaps of that sort.

What's the middle space for here?

Tail-gate parties... do they have those in Jolly Old...? :tongue:

Yes...

It's been said a few times that the figure applies to the first 50% of the pack.

 

[Babylonfive]

There you meet at the pub!

 

[AndrewBissell]

Yes...

It does mean that, somewhat ironically, to beat range anxiety (by using superchargers for a fast charge) you must embrace range anxiety (by arriving as close to zero state of charge as possible).

I think this is the second reported LA/SF Supercharger trip (after the official launch): (using all 7 seats)

Doing LA to SF road trip in Model S with all 5 kids & Talulah. Supercharger finished charging b4 we finished our burgers!

 

[strider]

Wait, are they back together?

Good for Elon if so. From the outside, she appeared to be level-headed and not a golddigger or any such thing.

 

[Grendal]

What an awesome tweet. Great picture. I never realized the P85 had a red P. And he's got a factual license too! Vin #2/2nd Model S made/2nd Tesla


I wonder how his range does with a completely full car?

On the highway it shouldn't make that much difference. Weight mostly affects range when there is a lot of stopping and starting.

It's the using all 7 seats out on public roads which is the significant bit, a first as far as I know, and a topic for a different thread.

Ahead of you, doug; posted it here last night:
