I hate to well, actually, to you, but the dynamic charging losses increase as the battery approaches 100%. Not only do chargers throttle down to keep the battery cool, they have to do cell balancing, and there are always losses in a charger: These are usually most extreme near the end of the charging cycle, as the voltage in the cells approaches the voltage of the charger.It's not a matter of cost,
It's a very small amount, but it would count, if you were measuring from the wall against miles driven.
But on the other hand, that cell balancing is healthy for the battery pack, and doing things like power battery management, pre-heat or pre-cooling, charging the aux battery, and powering the radios (for over the air updates) from the wall are things you probably don't want to do from the traction battery.
