Joshua, your statement is only half true. Both high and low battery temps affect battery performance and longevity significantly. Lets not mislead people on the forum. Heat is a very real problem with EV batteries for a number of reasons. Let’s not minimize it. Think for a minute. Why are there so many engineering articles published regarding EV battery cooling technology. Why is so much time spent trying to get battery cooling technology to work efficiently and effectively by Aptera and other EV companies. If heat is not an issue, why have a battery cooling system at all? Read about balancing temps between batter cells in your research to understand the challenges for battery cooling in a hot climate.
If you don’t think high battery high temps are an issue (Safety) review what GM has going on with the Bolt to the tune of $2B and a massive recall. It is not only battery chemistry. As you know, I drive a Model3 as well. In FL the issue is very definitely batter high temps for performance degradation. We have no winter here.😉
