Return of phantom 16 amp charging

[Durzel]

Is this problem not charger specific?

I've never had a problem with my Andersen A2 charging the car. Always been a solid 32A. I did a 4.5 hour charge last night, and kept checking it to see if it dropped but it stayed at 32A.

For what it's worth (not much really) this has been the case on all software versions I've been on. Currently on 2020.28.2.

Is this problem not charger specific?

No it's not charger specific. The charge points all continue to offer 32amps (including Tesla's own brand charge points) it's just the car that chooses to lower the rate it is taking. I only rarely saw the issue myself and only after the 24.6.4 update. Anyway, it has been confirmed that 28.2 finally clears the issue.

... until some other software version breaks it again....

Is this problem not charger specific?

No, but it may be specific the changes in voltage etc on the local electricity network.

Not sure if related or I have a worse issue.

I plug my car in and select 32a on the display. It ramps up and gets to 16amps but then reduces down to 0amps.
Tries to ramp up again and the same thing happens on loop. Tops out at 16amps then resets itself.

If I limit in the car to 16amps it will stay there fine but not 32amps.

Anyone had this? I suspect my cars charging equipment has developed a fault. Twin scroll button reset doesn’t help.

This is on mutliple chargers.

Best to submit a service request. They’ll have a look at logs and probably be able to tell whether it’s software of the onboard charger that’s faulty.

I seem to have software version 10.02 2020.20.17 I think.

The charge screen has 16/16 amps on it with 16 amps below with the + grayed out.

While it's plugged in?
If that's the case then one of the two will apply:
1 - You have three phase power, which will only give you 16A per phase
2 - You charger is only advertising 16A on single phase and therefore that's all the car can pull

Bear in mind that if the charging cable is not plugged in, the charging screen does indeed default to 16A and won't allow you to select any higher, but once you plug the charger in the car will pull as much juice as the charger advertises (when the software is working normally).

Car is plugged in and charging. My electrician assures me I have 32amp available.

 

[ACarneiro]

Which charger? And is it Three phase or single phase? How many kW is it pulling?

 

[LongRanger]

Mode F on that newer model seems somewhat politically topical and perhaps a little "David Ickes".

I have absolutely no idea what that means

There may be 32amp available from the mains to the charge point (which might be what the electrician is referring to) but that doesn't always mean that the charge point is offering 32amps to the car... or that the car is choosing to accept 32amps if offered ...

Im using the Tesla charger bought from Tesla.com. 500 bucks!!!

I'll get the sparky to come back and check all settings. This is obviously according to you helpful peeps a software issue.

Sorry I mean NOT a software issue....

The issue seesm to now be affecting me too. Charge current at bottom left is set to 32 amps, but the car is only drawing 18. This is during the day today. On overnight charging it seems ok, drawing 32.

... getting your installer back is clearly a good idea.

 

[KaiM]

I got 24.6.9 installed. Anyone tried charging on this version to test otherwise I'll report later on.

 

[ACarneiro]

Can’t wait for that one to land for me...
