Slow AC charging

[UncleArthur]

Last night my car charged between 1 - 2kW instead of the usual 7Kw. The setup was as follows:
- PodPoint charger, no schedule set.
- No schedule set on the car. 100% max SOC set on car.
- Charging schedule set via Octopus Intelligent Go, requesting 80% by 7am this morning.
- Starting SOC about 14% - ended up with only 26% (usually I can get to 80% between 11:30pm and 05:30am).
- The Octopus app correctly reported that the required SOC had not been reached, but no connectivity issues.
- I had returned from a 280mile trip at 8:30pm with a couple of short rapid charging sessions along the way, charging at up to 70kW as best as I can recall.

I wonder what might be the likely cause? My thoughts:
- Sub-zero temperature?
- I notice that the Grid CO2 emissions were very high last night - but surely Octopus wouldn't throttle the charging rate?

I have had the odd small issues charging via Octopus Intelligent Go, but it's much easier to use and more reliable that trying to use charging schedules via the Skoda app or via the PodPoint charger. Sometimes, when I request 80%, I end up with 81% or 82% (even 94%on one occasion), always accompanied by a message from the Octopus app saying "couldn't control your car", which I assume to be as a result of poor Skoda connectivity.

Any thoughts gratefully received.

If it’s not low power mode on car or charger, It can or could be the cold in a few ways.

If the charging port doesn’t lock properly, then the charging power is limited to 1 or 2 KW. It’s possible ice or something stopped it from locking properly. When it happened for us, my wife just hadn’t pushed the charger All the way in properly.

It can also happen if the car and charger communication doesn’t go as planned - which can happen if the car doesn’t wake up properly due to 12V battery protection or similar.

Finally some chargers have demand side response or similar enabled - letting them reduce charging power to help balance the grid. I think this is opt in rather than opt out but I could be wrong and don’t know your specific charger.

Thanks Enyaqandy24, a few good insights there. The Enyaq and PodPoint charger certainly don't like talking to each other - I used to get all sorts of spurious outcomes, which the Octopus app has mainly sorted out.

I just started a charge and the rate went straight up to 6kW. The SOC rose to 33% before the Octopus schedule kicked in and charging stopped. I'll charge again Sunday night when Grid CO2 is predicted to be much lower.

I don’t think any do. I think most start chargers that make power available or not (with starts delays, boosts, settings for pre-conditioning etc), all conflict at times with the Enyaq (and other VWG EVs).
