Here's one study you might be interested in. They only studied a grid-integrated vehicle system, but seem to think this is more efficient energy transfer than others.

About half way down the doc in Table 7 they put total % loss for their system at 17% loss charging with 10 amps and 36% on the discharge. For 40A, 12 and 29% respectively.
