I also learned that ‘fast-charging’ the batteries significantly reduces the life of the battery. The ol’ tried and true trickle charge is the way to go. So, the idea of fast-charging stations all over the U S A, to charge the Tesla’s etc. might sound good, but will shorten the battery’s life.
Charging is much more complex than that simple summary.
Suffice to say: the new batteries are made to last >1,000,000 miles, and most charging is done at home.
