Nissan engineers in the Phoenix area doing heat testing report 10-20% range reduction.
do you have a reference? I would love to read that report.
not for heat and this is a bit unrelated to charge capacity but the colder weather has reduced my efficiency by 15%.

my driving habits, routes, speeds, etc have not changed. driving conditions do create a variance of 4-7% but i am continuing to see 4.8 to 5 miles/Kw and have still not used any climate controls. i did get that portable heater for defrost purposes from Harbor Freight and am still evaluating its effects on my range after 2 days of use.
prelim reports; well, its electric so it does have some effect but on energy consumption screen, the needle does not move when its on or off. unlike heat; 3 Kw, Defrost 4.5 kw or rear defrost; 250 watts, the 12 volt heater does not move any needles.
its listed at 12 VDC and 13 amps. states should not be run more than 20 minutes at a time so we will see. the power cord does get slightly warm after a while. longest run time was this morning (breakfast with Son thru FF drive thru) about 20 minutes or so, maybe 25. but at $8.99 even if it burns up, its worth seeing if this is a good solution for defrost and a bit of warmth
its on a slide mount and this morning i used it to put it on my lap for a few minutes and it does provide a bit of warmth without being hot enough to burn me.
**edit** LOL!! got so sidetracked i forgot to respond to the post....
ya, anyway, heat can be a limiting factor on range in that the warmer the pack, the lower "100%" has to be to protect longevity. iow, hot weather like 90º may see only 95% pack capacity restrictions to prevent overcharging when compared to a temperature adjusted capacity to a standard conditions like ummm STP or 68º.
