2011-2017 Not possible to quickcharge for over 60minutes

Noticed on AZE0, most likely also same on ZE0. When quickcharging the charge will end abruptly when it reaches 60minutes. This is very noticeable on cold days, when quickcharging for instance a 62kWh battery. We need to look at the QC_Timer and see if this can be improved somehow.
