Nice of you to show so much faith
@iooi but I wasn't too sure what is included in what measurement either
I wish there was a more technical manual for curios chimps like me to go and clarify what's going on!
I too thought that "Electronics" might be
anything and everything on 12V (there's actually quite a lot) but we would expect the PTC heating to be a nice safe 12V, so wouldn't that get counted twice if it counted against climate and "electronics" I thought.
So what will be consuming 12V? Heating, fan, cooling A/C (maybe), lights, head-unit computer and displays (including radio), power to circuits for door locks sensing, engine/battery management, energised circuits for driving power to the motor, the vision for collision avoidance, the rain detector etc There's quite a lot in a modern car (whether EV or ICE)
I started with a Google for some clues about what might be "electronics" and what is "climate" and what is "battery care". I found a thread on SpeakEV which had a few ideas and initial ball-park figures
'Electronics' power consumption when driving
So I went outside for some experimentation. On a pre-lunch play I got an impression of what was going on, but I needed to go out again with a notepad because the numbers were varying and a bit muddled. I was using the EV display in the car because it gives a live representation of the power use across those categories - So much better than the history for the entire drive - You can turn things on and off and look at the results.
Sorry for wonky picture - car was facing wrong way and low winter sun...
I wasn't going to wait for dusk for shot!

In very broad-brush... I get in, turn the car fully on but have the climate fully off, lights off (as much as possible, but DRLs will be on because the car is "ready" to move). In this lowest power consumption that I can set, the power used is only "electronics" and it is about 0.2kW (200W). If I just st there and do nothing the electronics consumption doesn't remain static. It seems to steadily rise and fall between 0.21 and 0.28kW and it takes about 20 seconds for that cycle. The fact that it is rising and falling on its own creates a problem of clearly identifying how much difference turning things on makes and also begs the question "what is cycling this way?" I'm guessing that it is the way that the LDC (the Low voltage DC-DC converter) is behaving in order to charge the battery. After doing some tests with fan and heater and A/C I noticed that the "electronics" was only cycling between 0.20 and 0.23kW - maybe that hinted that the car was detecting the 12V battery as needing less top-up?
Turn fan on: max fan caused "electronics" to hit 0.32kW ranging down to 0.25
Heat on (27C, mid fan): Climate = 2.2kW, Electronics = 0.26 (so it looks like heating power is not included in electronics)
A/C on (thermostat 17): Climate = 0 ! Electronic - 0.28 (odd no climate, but ambient temperature was already below threshold), so have A/C on and temperature set to 22C: Climate = 0.42kW, Electronics = 0.21 (looks like the A/C power and heating have come to more power than when I was just heating - as you would expect)
All Off again: Electronics = 0.21 - 0.23kW cycle - Hmm 12V battery requiring less charging?
Full lights (high-beam + front & rear fogs + brake lights): Electronics 0.37kW
Interesting that we can see that turning all lights on doesn't get anywhere near the sort of power that resistive heating uses, and you wouldn't have your foot on the brake long or the fog lamps in use often, so don't fret about lights, certainly not the front LED headlights.
Using an OBD2 diagnosic port dongle I could see what current the LDC was supplying. When power was minimal (but with that 20 second cycling) the "AUX Amps LDC" was reading 12.4 - 13.2A. With fan on it became 19A. With full lights it was 20-25A.
From what I've read elsewhere the "Battery care" is battery heating, so I'm not sure that I have ever (or ever will) see that as anything but zero for two reasons (a) my Soul EV doesn't have a battery heater to the best of my knowledge and (b) it would only get used in some very cold temperatures and niche conditions. Kia are more frugal than Tesla with throwing kWatts at heating a battery in order to deliver "performance" acceleration or "performance" fast charging. I am "OK" with that choice, but maybe it would be nice to press a button to say "warm my battery in preparation for charging in 20 minutes time".
I think I've noted in the past that on freezing mornings I've seen several kW of power going to heating, today there was 2.2kW when the car was aimed at 27C, but if I had lowered the temp or allowed it to reach the target the ongoing maintenance of that temperature drops off quite a lot. I think I've seen it down to 0.4kW, but that might be resistive (PTC) heating which is now operating gently or it might be the Soul First Edition's heat-pump taking heat from the motor and motor drive electronics and pumping it to the cabin (and maybe battery).
Still lots of unknown unknowns!
Bottom line: There's lots of electronics. Don't forget that an "on" car charges the 12V battery electronically. Although the heating is done from the 12V (I'm pretty sure) it is accounted for as "climate" and Kia must therefore be subtracting it from the "electronics" power.
Perhaps have a look at the owner's manual section on fuses to see how many fused subsystems there are and what the fuse ratings are (for indicative relative power).
