I ran across this article today:
Asymmetric Temperature Modulation for Extreme Fast Charging of Lithium-Ion Batteries - ScienceDirect
The article is titled “Asymmetric Temperature Modulation for Extreme Fast Charging of Lithium-Ion Batteries.
Engineers from Penn State published a study showing increased efficiency of fast lithium ion battery charging at higher temperatures. We knew that; it’s why on-route battery warmup was such a boon to Supercharging. The interesting thing is their finding that the infamous lithium plating - the thing that plagues all of our batteries and is the main underlying cause behind progressive loss of capacity - doesn’t occur much at temperatures above 50 deg C. A temperature which, if I recall correctly, is the target temp for Max Battery Power in performance Teslas with Insane+/Ludicrous+. Makes you wonder if heating your battery all the way up with Max Battery Power prior to charging might extend the life of your battery...
