So add on about 12% onto a time estimate to account for the extra charging time. I'm estimating about 2.5 hours for 150 miles which isn't unreasonable for freeway driving.
If you're going < 300 miles, then it's really a moot point anyways. At that range, you'll have enough in the battery before leaving to get you there without a charge along the way.
And that's awesome until yo need to go beyond that single charge range. Then charging might be a problem where ever you wind up still, though it is getting much better I admit.
