I think you'll be more than fine with that arrangement. If you drive conservatively, 35 miles each way with (I'm assuming) around 8-10 hours to "top off" while at work, your commute should be easily handled.
Assuming you head to work with a full charge, after 35 miles you should have about half a charge left. Then, 8-10 hours of charge time while working should leave you with nearly a full charge again. Whatever the case, you should have more than enough to drive the 35 miles back home.
Once you get home (again, about half a charge left after driving 35 miles), you should have plenty of time (overnight) to reach a full charge again for the morning.
