Can you preheat the battery?
Basic principle here is that you can set a pre-departure timer (either when on charge or not) and a pre-heated (or cooled interior) cabin. This will raise the temperature of the battery simply because the battery (when not on charge) is being used to power the heat pump which naturally will heat the battery to a degree.
