Dennis, I have the same cells and almost identical pack size. Entering my fourth winter I would say that my range takes about a 20-25% hit in the winter. As previously mentioned by Russ it’s a combination of things: heat, wipers, road conditions, and the fact that the chemistry just isn’t as efficient in cold weather.
For comparison I also have a Tesla. Even with the thermal battery pack management and all the other fancy stuff I’ve found that in the winter it’s range is reduced by about 10-20% depending on conditions.
