Interesting data, but for the Model 3, I think an important piece is missing: model year. Around 2021 they switched out the resistive cabin heating for heat pump heating, which had a positive impact on cold weather range. Anecdotally speaking, my 2020 Model 3 gets between a 30-40% range hit in the winter.
- Someone1234 4y agoThis article is about battery capacity loss due to cold weather (either directly or due to use of battery-heaters). Cabin heating is over and above the loss discussed here.
- tedd4u 4y agoThe article explicitly compares real-world data as experienced during on-road usage, showing how EVs with more efficient cabin heating (heat pump e.g.) lose less range in the cold.
- mannykannot 4y agoThis is explicitly a study of real-world driving experiences, so, unless people generally drive through winter without cabin heating, then to exclude its effects, their use of it must be controlled for, and I see no evidence that they have done so. In fact, this paragraph about the BMW i3 suggests that they are lumping together cars having different cabin heating methods and options, if they are the same make and model: This little BMW clearly experiences some winter range loss in cold temperatures. But keep in mind that many i3 models include a heat pump in the US and some feature a gasoline range extender (called REx). Both of those help to preserve range in cold temperature.
