2021 Soul EV FE
Yep - Cocijo is right. The pre-heat is designed to work from external power. The AC power has to be available from the cable. It was a design to maximise people's battery range by heating the car from the mains before you get in, you begin your journey on 100% SOC and the car is already warm, so it is only having to use relatively little energy keeping the temperature topped-up.On my Maxx if plugged in with the charge completed ( for example I tend to charge between 00.30 and 04.30), if remote heating is activated it starts to charge pulling around 7kwh from my wall charger.
Nope, sorry. Scheduled pre-heating requires to be plugged in. It says so in the manual. Plugged-in with no volts doesn't work as a cheat!I don't have a Soul EV yet but would guess that if the charger is off then it would use the main battery.
Can you check the charger status, separate from the car, to see if it's operating during the preheat process?
If you want the car warmed at the expense of the battery you can do it, but it has to be by using the Connect app to manually start remote climate. I guess they don't mind this because the use-case is for a human making a decision that climate is required "now" (whether that is cooling the car in a hot summer car park or warming it or warming it outside your home).
Imagine if you had an "all week" schedule and forget to plug in one night you might lose a bit of SOC, but go away for a week or more and you have the makings of a problem!
Unfortunately the "scheduled climate" is more of a problem with people who have smart chargers which of necessity follow agile tariffs. For simple off-peak times you might as well use the settings in the car and ignore timers in the smart wall-box.
If you only want to use the kWh from the cheap time then you have to use the Connect app to manually start during your breakfast - You can't schedule heating from battery.
