    Yeah, I've been driving with it on for about a month now. Temperatures get only down to about 30°C during the night. 45°C during the day. Good thing for remote AC!

    Almost looks like the chiller mode came on :

    Domenick (or any other Administrator): can we merge these 2 threads ?

    When mine came on today it drew 1.8kW! The first time I've seen that.

    So no abnormal mechanical sounds (other than relays clicking) ?

    No, nothing abnormal.

    Interesting that mine only pulled 0.56 kw and yours 1.8kw. I did not hear anything coming on. All that I noticed was the draw in the battery sub menu..

    Yeah, this is the first time I noticed it was drawing that much. All the other times it was only around 0.6kW. But good to see that it you're to cool the battery quickly if it has to.

    It would be nice to see the actual temperature of the pack when these differences occur and the cooling effect. Too bad Hyundai didn't equip the Kona EV with this feature (either in bar format or some kind of gauge)

    I’m always down for extra information more for curiosity sake then other reasons but I totally get why Hyundai completely hides that info... is just too much information stress for people. Just look at how much stress people are under and the conversations about batteries -as is-. People act like the batteries have 5 charges and are hyper delicate to the world around them and need to be coddled. Raw temp data’s, highs & lows and cooling / warming cycles would just have people pulling their hair out demanding to know why they’re nearly 35c and the cooling system still isn’t on etc. Such thing as too much information. People need to stop worrying and fixating on them in the end. I don’t ever recall that kind of detailed temp info readouts on our old ICE vehicles. One of my cars didn’t even have a temp gauge at all just a light that would come on if the car was overheating.

    You are probably right, but I still would prefer to have one.

    Owners of older BMWs might recall that their coolant temp gauge needle sits directly in the center under normal conditions. Only if the coolant is cold or overheated does it deviate. A warning light presumably wasn't considered fitting for an expensive car, but you can imagine concerned owners complaining about the needle being 2 millimeters one side of the other. Look how we fuss over the GoM, hardly better than a random number generator!

    Everything you're looking for can be displayed with OBD2 reader and appropriate smartphone app. You have 5 modules temperature sensors, inlet coolant temperature sensor, etc.

    Exactly , I would much rather have an accurate reading on a display instead of say a compass.

    I would bet that the battery temperature information is available, we would just need a way to access it..

    You got me worried now, my 335i convertible coolant needle is slightly under the middle. Hehehehe
