I assume you saw this article in Electrek yesterday. Study shows electric cars lose 41% of range in ‘icy temperature’, Tesla disputes the claim Tesla is disputing, but I was forced to run my defrosters for the entire trip and it will kill the battery. I must have a moisture leak in the car that fogs up the entire car forcing me to run the defrosters at 11 full heat costing me 10 miles right off the bat. I can throttle back but still must run temp above normal when it happens. Which it has 4 times now. So the article is correct if you are not prepared or preheated, including the battery temp. the car is always trying to catch up. If you plan ahead and can preheat the car it is not true. That little prep time makes a big difference in range. I did the same when I was in Mass last week with 10 degree weather. I preheated the car real good and then had little effect when I was driving. I've seen readings as high as 560 and dropped yesterday down to 260. Back to the thread June is the opening date plus or minus. it was delayed from last November.
