Charging current?

Range of an EV has to be highly qualified. Under what conditions are you asking? If one lives in a moderate climate (e.g. southern California), and drives mostly city streets, the range should far exceed 110 miles. But if one lives in a cold climate (e.g. Montana) and drives mostly highway (80+ MPH in Montana), 110 miles would not be possible in late December.
 
Not all EV manufacturers are smart enough to ensure the 12V battery is also maintained when the car is plugged into the Level 2 charger.
This part is certainly true. I had a 2012 Nissan Leaf. It would charge the 12V battery while the HV (high voltage) battery was charging, but would not keep doing so when the HV battery was full. This led to a strange situation where it was actually better to leave the car unplugged than plugged in. If it was plugged in, the car would "wake up" periodically and check the wall voltage and the cell balance in the battery. All that was powered off the 12V battery only, and would eventually kill the 12V battery, even though the car was plugged in. It was a terrible design flaw, and one that I believe Nissan has since fixed. I have to believe that the Mini SE will not have this issue, though, as it would have already been caught / fixed in the i3.
