I've read on this forum and on other sites that "rapid charging" is, or at least can be harmful. If this is so why is it that Tesla's and Electrify America charging systems are (when working correctly) designed to do just that? What exactly is it that fast charging does to the battery array of these cars that is detrimental to their long life? Heat build up? If it is a known issue why then would VW want to offer three years of rapid free charging @ Electrify America locations? What am I missing here?
