I park in my driveway and charge to 80%. Overnight it’s in the mid to low 60s. When I leave in the morning I always have a few dashes under the PRND energy use bar. Today it took a good 20 minutes of driving to go away. I had finished an hours worth of charging just before I left. Is there anything I can do to have it working when I leave. What about winter when it gets way colder?
