Use of Tesla Superchargers

[Gen-EV]

Is there anyone that has charged a G80 following this thread? The G80 is not on a full E-GMP platforrn so I'm wondering what charging speeds I will see.

Good post. You're correct about the 4 pylons. An even more so because it's basically a REQUIRED stop for CCS GV60s between Phoenix and LA. If Quartzite is unavailable, you've got a 219mi stretch between Buckeye and Indio which you likely won't make at I-10 freeway speed. I don't think there are any alternatives.

There's a similar choke point between Phoenix and Vegas which is just about impossible without the 4 stall EA station in Kingman.

Wow - I wasn’t aware of the Phoenix-Las Vegas charging conundrum.

Looking now though, it appears that this Supercharger location in Kingman would be an alternative? :

Are you asking what the max charging rate will be or the time from 10-80% will be specifically on a Tesla Supercharger?

Yes, sorry I was referring to the situation BEFORE access to the SC Network charging only on CCS plugs. That's why SC access is so huge for those of us out West where distances are long. The SC network is a game changer for EV road trips here.

Most directions out of Phoenix are/were highly dependent on a single 4 stall charging stations including Payson (popular route to Albuquerque and AZ mountain destinations). Flagstaff & Kanab (going to Salt Lake City). Routes to San Diego and El Paso are slightly better, with a little flexibility, but it's still pretty sketchy unless you can depend on ALL the charging stations being available. Tesla has BIG stations at all these locations and more, it should pretty much eliminate charging anxiety for all major routes, though you still have to plan.

EDIT: Oh, and if you rely on say PlugShare to find stations, you have to be a little careful. There are several Rivian-only CCS stations at critical points (incl Kingman) which are difficult/impossible to filter out on PlugShare, so you might head there only to find out you can't use them.

I for one would like a report post-trip, should SWMBO deign to provide....

Mid-trip report:

Amazingly, there was a single open (edited) EA charger when she arrived in Quartzite, and the session proceeded without a hitch.

When she left after 15 minutes of charging, the EA station was full and had 3 cars waiting.

Wait.. what??
84 chargers were in use... with 3 waiting?? That's insane.

Since you didn't put any joke emoji on this, maybe you didn't realize he was talking about the EA station, not the Tesla one. So she used the free (and faster) EA charging, rather than paying at Tesla.

If you did realize this, my apologies for an unnecessary clarification.

 

[Zcd1]

Yep, my bad for not clarifying that.

I’ve edited the post accordingly.

For what it’s worth, I was monitoring the station availability before and after her session and it was completely full almost every time I checked. She simply lucked out with her timing.

I should also add that each fully functional EA session we experience demonstrates this platform’s amazing charging capabilities. SWMBO even said, without prompting, that the car was finished charging before she was finished doing what she needed to do at the stop.

Peak speed was 235KW and less than 15 minutes from 38-82%.

Yes specifically the charging rate in kW and the time from 10%-80% SOC. (or what ever the poster charged to)

Obviously, I don't have any experience. But I'm guessing that once they put all the hardware in place for the V4 chargers, you should get the same results on those as you get on an EA charger. That's what, a peak of about 200kw and 22 minutes?

On the V3 chargers, since your battery is the same voltage as the GV60, I'm guessing you'll probably get the same 100 - 120 kw as us. At the 120kw level that the new Ioniq5 got, it took the Ioniq Guy 30 minutes to go from 10 - 80%. At 100kw, it should probably take about 20% longer or about 35 minutes or so? Since your battery is about 10% larger than ours, I would think those times would increase proportionally. That would mean about 33 to 38 minutes.

Just a guess though. The only way to know is to take yours out to a charger at a low SOC, hook it up and see what rates you get. Assuming the rate is relatively low, it will probably hold that rate all the way, or nearly all the way, to 80%. Once you know the rate and battery capacity, it's just a matter of math to figure out the time from 10-80%.

Personally, in the US, I'm only planning on using the V3 chargers as a backup. On a Canadian sightseeing trip my wife and I plan to do in the next year and a half or so, I'll probably plan on using them almost exclusively because even at the lower rate, they will still be faster than the BC Hydro alternative.

It's got nothing to do with the battery voltage - the rate is limited by the capacity of the 400v -> 800v converter built into the car. On the EGMP cars Hyundai has touted that they use the windings in the rear motor as a component in this converter (since when you're stopped, those windings aren't doing anything). But the GV80 does not use EGMP platform, so I don't think it has this featue. In any case, this YouTuber tried it on a magic dock and got 49kw (similar to the Lucid Air).

On the other hand, in the early days the EGMP cars were also getting only 49kw on Magic Dock's, then Tesla made an adjustment and it jumped to 97kw. Since this video is about a year old, maybe it is out of date. But it was the most recent one I could find. You'll have to try it and see.

Ok, I found another video, Brandon Flasch actually got 122 kW! These two videos were made only about a week apart, so who knows what the difference is. Maybe it varies between different Tesla stations. Brandon also had quite a few details about how the G80 differs from EGMP cars, apparently the pack voltage is only about 520v, vs. 750-800 in EGMP cars, so maybe the voltage converter is simpler. Brandon always does a good job in his videos, so you might want to check this one out.

Trip update:

2 more EA charging sessions earlier this weekend, 1 with no problem, 1 where she had to wait 25 minutes for an open charger . In addition, once she started charging, a Honda Prologue pulled up but couldn't reach the adjacent charger, so she moved the already-positioned, already-charging GV60 over, slightly outside of its defined charging space, to enable the Prologue to charge. That left the Prologue so close to the GV60 that the GV60's driver's door was inaccessible, so she had to enter via the passenger door and clamber over the center console. Whoops, but at least the Prologue driver and SWMBO worked together to make it work! This neatly illustrates the problem with no standardized charge port location.

The final charging session today proved that my fears about that Quartzite EA station were well-founded, as the station was full with 5 cars waiting when she arrived. Indeed, the app showed the station as full almost all day - not surprising on a Sunday.

She simply went across the highway to the Tesla Supercharger, where 43 of the 84 stalls (!!!!) were available.

(Side note - that means there were 42 cars charging at one time while she was there - holee sh*t!!!)

Moral of the story: Supercharger access may save your bacon at some point, so get an adapter and set up an account!

…the GV60's driver's door was inaccessible, so she had to enter via the passenger door and clamber over the center console.

A perfect opportunity to use the remote control vehicle movement feature!

No, because she wanted to sit in the car while it was charging, but I get your point....

Great videos GVJIM.
I was feeling down when I saw 49kW but the poster said he did not precondition so I hope that was the difference.
We have no magic docks in Ohio so I need that adapter. I hope we get that email this week!

While the Plugshare app does not distinguish between Tesla only and Other Ev's by symbol on the map, if you select the charger, it tells you whether or not we can use it.

From what I can tell, any Supercharger we can use that is rated at 250kw is a V3 charger and we will likely get a max rate of about 100 - 120kw. I believe V4 chargers are rated at 325kw and since they can put out 1000v, we should get everything our cars ask for.

Yeah, that's what I was saying as well.
