My Bolt routinely averages over 4 miles per kwh from the pack, about 3.8 mpk from the wall. About 1/2 my driving is at speeds of 65mph and above.
My wife averages about 5 mpk from the batteries in her Volt, but she mostly drives at less than 50mph. FWIW The Volt is somewhat more effecient at charging because it never allows the batteries to fully charge or discharge, in this zone the battery kwh charge efficeincy is near 100%. No high voltage to force the last few AH in and no running at reduced voltage as they get near the bottom. FWIW Level 2 charging seems more efficient than level-1, I suspect becase you spend less time running the fans and pumps, etc. My PGP public key: https://vanderwal.us/evdl_pgp.key December 30, 2021 7:32 AM, "Peri Hartman via EV" <[email protected]> wrote: > That's very cool to hear.
