Probably not new news to some of you, but i learned a lesson today. Left home with a full charge this morning (reading 335 mile range). Entered destination into GPS (120 miles away) and it estimated 54% remaining (180 miles) when i arrive. Noteworthy, as i was planning to drive back same day....no charging. Drive around maybe 8 miles in town when i get to destination. Return (same route) GPS estimates 9% battery remaining (30 miles) when I arrive. So off I go. I get back in my home town and make a stop; car sits in the sweltering heat for maybe 35 minutes. When i get back in, the alert says 'cabin overheat protection disabled' due to low battery. When i finally get home, i have 19 miles of range left. Total trip, 263.6 miles. So you definitely cannot take off assuming 335 miles of range (without a planned charge stop) on a super hot day with mixed driving of 45mph - 80mph. You may not make it home....even if your trip is estimated (by you) to require only 79% of your battery. Yes, I know this is covered in several topics here (now that I had a reason to search/read). Now to my question: Should i avoid plugging the car in immediately considering the 4+ hours of driving in 100 degree heat? Should i let it cool down first, or does it not matter? Thanks!
