Hi, first timer here. :D

The Climate Control Plan doesn't use the charging station even when fully connected. The car uses the battery for pre-heating.

In the evening, I connect the car to the Charging Station (CS), the car charges to the 80% target and the car stops charging.
I usually set the CS to 2.5 kW.

After charging, the CS's application displays this message: "Car stopped charging. Charging allowed".

The Climate Control Plan instructs the car to pre-heat Monday to Friday at 8:15 with a target of 20 C.
When the heating happens, the car doesn't use any power from the CS, the car heats itself up only from the battery.
The CS's application displays the "Car stopped charging. Charging allowed" message for the entire time the cars heats up using the battery.

Q: Why does the car heat itself up only from the battery and not use the CS at all?

This process has worked before with my VW Passat GTE PHEV.
When the GTE heated up in the morning, the CS's app was showing power going to the car like when the car was charging.
The CS's app doesn't know what the car uses the power for.

Does the car have a schedule/restricted hours set for the charge location?

No, there aren't any Preferred charging times.

Hm, even though I've only got a 1.8kW charger currently, it does seem to use this in combination with the battery during preheating when I trigger it from phone, at least, the app indicates charging is negative, but not by as much as I'd expect if wasn't using external power to help, and returns to showing a positive charging after about 10 minutes.

all i can tell you from my personal experience is that without any outside intervention, the car does indeed use the charger while pre-heating.

Here for instance is last weekend. Car was set to charge to 100% and was in the high 90's (hence the lower than normal charge current). Around 7:30 i started the pre-heat on the app:

And here is another example from a few weeks back. Car finished charging at 5:50am, and just after 7am i started the pre-heat on the app:

I have however seen the opposite occur. If Octopus stops the charge before the car has reached its target, EG Octopus is set to 90% and the car is set to 100%, then the car will pre-heat from the battery instead.

Today I proactively increased the station's power to 3.5 kW and the car did use that power for heating.

I also noticed that the car's software is at the 3.2 version and it's reporting that the 3.7 version is available.
The message says to perform the update at the service so I have booked a reservation at the service for the update.

Let's see if the behavior will be different when the new software will be running.

Make sure you are aware of the "fuse 3" reset that probably will need to be done after upgrading to 3.7 to get the charging working properly.

I think the car always preheats via the battery, there is no concept of a heating system powered directly by the charger, but a) if the car is plugged in, and b) if it doesn't have a restrictive schedule, and c) the charger doesn't have a restrictive schedule and/or it doesn't prevent the charge in any other way*, and d) the whole charge is not restricted by the supplier - if you have a smart tariff - then the car conserves the battery SoC by trickle charging from the station while preheating.
In this case, the skoda app will show "conserving" instead of "charging", because it's not trying to increase the SoC, it's just keeping it where it was at the start of the pre-heating.


Depending on the behaviour of your charger's app, you may also see trickle charging taking place. I do with Hypervolt.

*In your case, perhaps the setting of the charger prevented the trickle charging, or the car needs a min power and the increase in kW sorted it out.

I have not tried using a climate control schedule, but, possibly apart from b), that is the behaviour I see.

After updating from SW 3.5 to 3.7 last week I tried charging to 80% with no charger schedule and Intelligent Octopus smart charging disabled, but the car supposed to set to charge during perferred times (23:35 to 05:25) only and then left the car connected to the charger until the following afternoon. The car went to "Conserving charge" and took a small amount of power at about 08:00 and again at about 11:00. When preconditioning was turned on using the app in the afternoon the car went to "Conserving charge" but for the first 4 minutes only used battery power. After using about 0.4 kWh from the battery, and the BMS state of charge dropping by approximately 0.5% the car started drawing 2.5 kW from the charger, topping up the battery as well as supplying power for heating.

I intend to repeat the test sometime after double checking the car's charge time settings.

The MySkoda app and the car have 2 different settings for pre-heating the car:
  1. Climate Control Plans that you can set to heat up the car every work day morning. This is considered Stationary Heating and can be activated anywhere, not necessarily when connected to a Charging Station (CS). It makes sense why heating up the car using this setting would use the battery.
  2. Departure Time + Climate Control Charging Mode at a configured Charging Location can also be set at a specific time on every work day morning. This seems to do what I wanted to do. To charge the car and have the battery heated up by the charging process as close as possible to the departure time and heat up the car using power from the CS.
My question would be: aren't the scheduling plans for Departure Time + Climate Control enough? What do the scheduling plans for Climate Control bring extra?
