Does Cold Weather Hurt Or Help Tesla Batteries? This New Study Found The Answer

The batteries powering electric cars don't always play well with cold surroundings, but it seems Tesla cars do a fine job of handling low temperatures and exhibit a lower impact with regard to range output. According to research by Recurrent, Tesla car batteries that have thrived in areas with a colder climate take a smaller hit and can put more miles per charge compared to EVs driven in hot and humid areas.

The study measured the impact of hot and cold environments on Tesla car batteries in terms of Range Score. In a nutshell, it's a percentage estimation of how many miles a used Tesla can go on a single charge, compared to the range figures touted by the brand. Think of it like the battery health system on an iPhone, which tells how efficient the battery is at retaining electrical energy compared to its new state.

Per the data collected by Recurrent, the Range Score for Tesla cars in areas classified as "cold," "very cold," "subarctic," and "marine" was 95, compared to the Range Score of 92 for vehicles located in "humid hot" and "dry hot" areas. That means Tesla driven in chilly areas experience a smaller degree of range degradation compared to those in hot climates.
