I recently had my first experiences using Tesla SuperCharger sites: one at Hollydene, in the NSW Hunter Valley and the other at Bathurst, in the central west. The Hollydene site is delightful, located at a restaurant within a vineyard and winery. It is open 24/7 and it rated at up to 120kW: none of the 6 stalls was in use when we arrived and no-one else came in while we were there.
The more 'interesting' experience was at Bathurst, which is also rated at 120kW and has 6 stalls open 24/7. We began charging at 97kW and we were the only vehicle connected. After ~15minutes, a Tesla Model S arrived and connected a couple of charging stations along. Within less than a minute of the Tesla plugging in, we were disconnected. I un-plugged and then re-connected (same cable/station) but our charging rate reduced to about 43kW.

I wonder if Tesla is prioritizing Tesla's at these open-to-non-Tesla sites? The chatty Tesla owner told me he was receiving about 80kW, so very roughly his charge was double mine and the total of our charging was about the site total of 120kW. No other vehicles arrived while we were there. I can imagine it making sense that non-Tesla's would be disconnected momentarily to allow a newly-connected Tesla to connect and establish its charge demand, then non-Tesla's connect and can access the balance of the available site capacity.

I am not complaining about this by the way: Tesla has received (almost) no public funding in Australia for its sites to date and their network is so extensive by comparison to the non-Tesla networks (particularly outside metro areas) that we are lucky to be able to access some of them. Just thought this charging behaviour was interesting and wondered if anyone else has observed this?

Excellent observation and logical explanation. Would you grant permission to copy paragraphs 2 & 3 to post (with credit to TealG) on our WVEAA Facebook group page?

Well, in all fairness, it could also be the car, as the SOC increases, the charging speed decreases.

Considering their stations are only 480 volt, they won't charge as fast as the 600+ volt that other DC Fast Chargers charge at.

Also, Tesla Superchargers have shared power, usually between two stations, but those two stations don't have to be next to each other, so you may have been able to get faster charging by moving to another station at that point.

The good news is it worked for you, a lot of people have had problems even getting them to work with the Ioniq 5.

You can also use an OBDII dongle and car scanner app to see what charging rate the car is requesting from the charger.

Have you found that Car Scanner is easier to set up and use than Torque Pro (with which I am having a great deal of trouble)?

Why would the Aussie 2023 Ioniq 5 work on the Tesla Superchargers and not the American? Does not sound like the OP had any problems initiating a charging session. Too bad he did not report his initial state of charge.

I am using an OBD dongle and app to monitor temperatures. Since I live in North Dakota, I get to see my battery pack temperature decrease while testing on the highway! Yeah, it has been cold here. Warm weather coming tho, up to 30F next week! Well, we call that warm!

It is my understanding that in Europe Tesla uses CSS2 connectors as it is required by law. That makes Tesla and non-Tesla cars plug and protocol compatible. If a non-Tesla can't charge at a Tesla charging station it is only due to software handshaking on authentication and billing.

Maybe Australia also requires a single charging standard too. I am sure one of our Australian members will clarify.

Pretty much same as Europe. Newer EVs, including Tesla, use CCS2. Some older EVs use type 1 or CHADEMO.

Older Teslas use proprietary plugs, but have been given, or have had to purchase, Tesla to CCS2 taps.

Tesla is trialling the opening of some chargers to non-Tesla vehicles although this may change over time. Costs are pretty prohibitive though.

My understanding is that the European HI5s are having the same issue as the North American HI5s. But, the NA Genesis GV60 does not have a charging problem on the Tesla Superchargers in spite of the having the same platform as the HI5. Some clarification from Europe would be appreciated.

From my standpoint, the Tesla chargers are the only option for travelling cross country. If a city in my area has a CCS, it is only a 62 kW unit. There is even one stretch of 200 miles on a east-west interstate where there are no CCS chargers. Unless I drive substantially under the speed limit of 80 mph, I cannot make that distance during the winter. I am not certain I can make that distance during the warmer months, even at 75 mph. More than 5 mph under the speed limit and a vehicle becomes a traffic hazard tho adaptive cruise control helps under those conditions. There is a Tesla Supercharger at 100 miles, pretty much the set spacing along this interstate.

Thanks to all for responding to my questions.

Ok, just found an article on 'Electrifying'. According to the article, HI5s can charge on Tesla V2 chargers in Europe, not the V3 chargers. I believe all of the Magic Dock chargers in the US are V3.

Currently there are no Magic Dock equipped SuperChargers located within 1,000+ miles of us. Even if there were any, I don't see them often being the best option, given the cost and lower power with Ioniq 5s. In time that could change. While we rarely need to use DCFC, I do believe having all chargers available to all EVs is important to EV adoption.

Two Tesla stalls are connected to one cabinet and share the available power, so if another car pulls up and connects to the shared shared stall, you should be halved or something along those lines.

They are normally labelled to make the pattern obvious such as

A A B B

or

A B A B

No problem Falcon68....glad it was helpful

My initial state of charge was 14%...sorry for not noting that, you are right that that is a material factor. However at 14% I should have been receiving a close-to-max charge rate, so I think my conclusion still stands

Good to know....thanks for this info

Seeing stray bits of info that the Ioniq5 and its ilk can charge at the Superchargers but only around 40-50 kW. Hyundai/Kia is looking into it. On the surface, that low charge rate does not make sense so let's hope this is just a software issue, such as communication with the Tesla Supercharger. At the very least, we may be able to use them as emergency chargers, eventually. Good luck!
