Hi Guys,
Although annoying when you are waiting in the car for a long period you have to keep resetting the start button every so often, lets NOT forget that it is like this for a reason. We all know now how important it is for ALL electric cars to have the 12v DC battery in good condition (i.e. holding a good charge) and when the Main Battery is off line any electric usage will come off the 12V battery and therefore the potential to have a non-runner after (if it was able to do so, or even continuous turning on and off the start button) sitting for half an hour to 45 mins is not a situation you want. Take it as it is, a design feature that is required.
All my recent ICE cars also had the same function although a flat battery in those are not such a problem. So as Chris says, and I do as well, if you are waiting just keep the car in the ready mode, the battery is kept healthy and if hot or cold you can use the HVAC to your hearts content. Sitting there without moving will not take much charge at all and of course (unlike your ICE Car) you are not polluting the air in and around your car.
While we are talking about batteries, all the faffing about keeping the car charged at certain levels is in my opinion a bloody nuisance and NOT required. Let the BMS do its job, it STOPS over and under charging and you also have the 7yr Battery Warranty to fall back on. If you are fortunate enough to have a wall charger at home, plug the car in every time you are not using it, you then (hopefully) will NEVER have a 12v Battery problem and if an emergency occurs you will have the car at its best charge. EV maxim, always charge it when possible.
Regards
Frank
PS The day time running lights are LED I believe which even if you use them 4 hours every day of the year that should still be going as LED's usually have 30000 -50000 hours life which means it most cases either the car has gone (worn out/sold), you have past away or your wife's got it in the Divorce settlement!!!!
