If my understanding is correct, I can take your 3ph 5A and count it as 15A. Working the numbers, one would expect somewhere around 85.7% charging efficiency. Your kWh numbers work out to 81.8%, but I''m not sure how you are measuring energy delivered by the battery (you could be missing standby usage for example, if using the trip meters).
However, the wall charger reported using 44.6kWh. Efficiency using the above equation it came out to 88.9% (44.6/39.68). Afterwards I charged from 80 to 100% and the efficiency dropped to 80% – it is more cost effective to charge to 80%! The efficiency of charging is well documented. EV manufacturers post the efficiency figures for their cars ...
