That is what I have found in my charging experiments.
L1 was much less efficient than L2.
Charging at 110V adding about 15 kWh and stopping 80% charging losses were 18 - 19%. Charging on 220V, adding 15 kWh and stopping at 80 had 7% charging losses.
Charging at lower SoC is more efficient than at high Soc.
When I was charging to 100% and adding 12 kWh on Level 2 losses were 19%
When I charged to 100% and added 34 kWh on L2 losses were 11.4%
When I charged to 80% and added 33 kWh on L2 the losses were only 6%
