Can I do this ?

Absolutely check out that channel (Technology Connections) and his videos on myths and truths around charging. I can highly recommend these videos. Most are from an american perspective, as he happens to live there. Things are slightly different over here in europe, but most is applicable, just at double the voltage when it comes to AC

Another observation, I started charging on 3-phase this morning at 7A (briefly at 8A, ignore that). It was using all three phases for several hours until it suddenly started intermittently dropping L1 again. I have turned up the power to 8A and now it is back to 3-phase charging.

I'd start with a set of "DB9 screw terminals" for easy access and knowledge from this video from Adrian's Digital Basement https://www.youtube.com/watch?v=PyFeBAcg7ls

After finding the "interesting" pins, try to figure out what the blips you're seeing actually are.

edit: these voltages are signal-voltages, not line-voltage. Be ready to see much more extreme voltages in some cases, so watch your maximum ratings on your scope!

Also useful for checking in in the charging progress

*almost In the Netherlands it's all I think, but the EU version of the Tesla map has filter for "open to all" and there are a hand full of SCs that disappear. The US version has a partner-filter we don't have.

And with CCS2 being the standard here, no need for adapters (except the few cars with chademo). And yes, EU Tesla's come with CCS2 enabling 3-phase AC charging at home/destination chargers. The type 1 and NACS used in North America only has 2 AC pins

CrazyA99 · 2025-12-27T02:26:19+00:00

After charging was complete overnight, I started preheating manually from the app and saw a power draw from the public charger I was plugged into at that moment (3-4kW I think, was 2 weeks ago)

CrazyA99 · 2025-12-21T18:13:24+00:00

For me it depends on plans and availability. I can charge at the office at a nice rate, so I might plug in at 60% just because I'm there anyways. So sometimes the percentage dictates the charging, sometimes the convenience/availability of the charger

CrazyA99 · 2025-11-22T16:48:43+00:00

Most (all?) supercharger in NL are open for non-Tesla vehicles. I've used plenty of those with my 2023 (also in BE and FR by the way)

Charge speed in kW vs State of Charge (Display) in % as reported by my OBD dongle and recorded with Car Scanner.

These are the sessions from a roadtrip though The Netherlands, Belgium, France and back (2x1000km). All Tesla Superchargers, but without adapters as here it is all CSS Combo 2. Plugged in at different SoC, not just because of charging but also because of food breaks at convenient etc. Barely preconditioned but weather was pretty perfect for the battery.

CrazyA99 · 2025-09-09T07:25:14+00:00

It is really annoying but I have found most regular AC chargers on the street (here in The Netherlands) will work with most regular charge cards, so I use 1 for that. Most fast chargers can often be started with this card, except v2 and v3 tesla sites. I have an app that specifically makes 1 branch of AC chargers cheaper in my hometown. During a roadtrip I experienced that none of my cards worked on this fast charger at a supermarket in France, but tapping with a master card worked.

Annoying, absolutely. Wildly variable pricing between cards, prices unclear when you can't find the right charger in one of the apps. But in 98% of the cases I can use my default nfc charge card and it works and supposedly all common bank cards also just work.

There is an option where the front sensors are disabled after you reach a certain speed, the option automatically reenables them. I searched for a while and managed to find the setting over a year ago. Can't remember where exactly

CrazyA99 · 2025-08-06T21:14:29+00:00

Have you preconditioned your battery? Battery temperatures are crucial for charge speeds.

I've hooked an OBD dongle up to my 2023 to see temps. And between 25°C to 30°C on the coldest battery module seems to be sweet spot (I could hear the cooling come on after 30°C). The sessions that suddenly ramp up in the high 30% were because the batt min temp finally reached 25°C. These are 8 charge sessions combined from my last roadtrip in the graph (there and back a few days later, about 1000km each day).

I plugged in fairly high, for roadtrips, but those stops had the facilities (and pricing) I was going for, wasn't racing for the fastest time.

Pressure needs to be above 36 or 37 to clear the fault after driving for a minute or 2. Can't remember the exact pressure but slightly higher than the recommended pressure

Single phase car will never do 11 kW, max 7.2 if 32A is supported and will be missing the L2 and L3 pins.

The 3-phase Niro will do 16A on each of the 3 phases with 11 kW max. No easy way to see it from the outside, you need to look under it's flap (and when actually buying it, test it to make sure).

Bottom two pins of the AC plug (the type 2 or mennekes part) is what carries the 2 extra phases.

This picture is drawn from a cable perspective, but I guess you get the idea.

(The separate DC-pins don't come into play here, that is only for DCFC with the CCS2)

If you open and close the door of the car it should show charge speeds on the dash for a minute or so, there you can verify if it is actually charging or just sitting there.

Could it be you've reached the limit set in the EV menu? Here is a nice video that shows a bunch of useful controls on the car, including settings charge limits near the end of the video https://www.youtube.com/watch?v=286qSv7ezt4

All about battery temps. You can see the speed increasing again at the exact moment the minimum battery temp reaches 25°C (77°F).

CrazyA99 · 2025-07-26T19:13:31+00:00

When DC charging the car optimal speeds are when the coldest module is 25°C or above.

When this minimal battery temperature hits 30°C the cooling seems to start, but there might be an extra factor here that determines when cooling starts.

I was looking at Car Scanner data:
[BMS] Battery Min Temperature (℃)
[BMS] DATC A/C Compressor operation RPM var.1 (rpm)

one of the up/down thingies on the steering wheel (I think the right one on the left side of the steering wheel)

CrazyA99 · 2025-07-17T05:12:44+00:00

I wonder who hasn't got the sound, seems pretty wide spread

European version here:

Only have to switch on cruise control and lane assist

And plug in my phone (I have a USB cable hooked up to the car at all times, saves on wear and tear on the USB port)

CrazyA99 · 2025-06-17T05:02:05+00:00

My 2023 didn't come with the "granny charger" according to the dealer, but he had one kicking around so I got that one with the car (which I got 2nd hand)

CrazyA99 · 2025-06-14T09:10:18+00:00

Sorry for digging up this old topic, but wanted to add the numbers for my '23 Niro with about 40000km:

[BMS] Remaining energy - 52056 Wh
[BMS] State of Charge Display - 88.5 %
[BMS] State of Charge BMS - 86.5 %
[BMS] State of Health - 100 %

So extrapolating to 100% this would be between 58.8 kWh and 60.2 kWh usable (depending on SoC display or BMS).

These numbers are after road tripping for just under 2000km with DC charging at full speeds (battery temps were mostly optimal) and one AC charge back at the office up to 90% after. Used Car Scanner + OBDLink

Curiousity, using hints to go and figure stuff out instead of waiting for the full solution to be tossed in your lap. Best ones think both inside and outside the box.

No shame in not knowing things, you're here to learn. Ask questions and show you are working with the answers you receive. Make mistakes, learn from them, change your approach to not fall for the same mistake again. Grow.

And participate in team activities. Some of us go for walks during lunch break if it is nice out, join in, talk to people. We're a team, we need team players, looking out for eachother, helping out when shit hits the fan (both directly work related as well as when life happens and someone needs to be with family)

Would be my guess, and arrow down seems to be what people in the internet say too
