As observed by a new study, the cold weather climatic condition is good for Tesla electric vehicle in the long-term longevity health of EV battery packs. Since it has been thought that the colder weather negatively affects the range in general.
Notably, recurrent has access to data from approximately 12,500 Tesla vehicles in the US via its software services. While this has been bringing new facts into Tesla batteries according to their data. Recently, it has been brought to notice that Tesla battery longevity is not hampered by frequent Supercharging. This significantly overcomes various myths that have been spreading for very long.
Range Score
Now, the firm is utilizing its data in order to demonstrate the impact of different climatic situations on battery longevity. It assigns a “range score” to every battery it tracks. Basically, it is the percentage of range retention. Considering an example, a Range Score of 90 would indicate that the battery pack has retained 90% of its original range.
As observed by the recurrent, Tesla vehicles in colder and coastal climates have a better Range Score as compared to the vehicles in hotter climates in the US. On the other hand, extreme cold negatively impacts the range of electric vehicles. This is because active thermal management uses a huge pack of energy in order to regulate the temperature.
In addition to this, this is completely new information for some people that in the long run of the battery pack. The colder temperature may prove to be good, or better than the hotter temperature.
According to Recurrent, the explanation for this happening is:
Batteries are a lot like people – always aging. We can do things to reduce these effects, like exercise and sleep, or things that accelerate them, such as smoking and tanning. The same is true of batteries, and being exposed to heat is a lot like smoking cigarettes. Environmental heat contributes extra energy to the electrochemical reactions in the battery, which can accelerate unwanted chemical reactions that age the battery prematurely. The generally accepted threshold for accelerated battery degradation is around 30 degrees C, or around 86 degrees F.
