To the extent that any EV has to be used for commutes, the answer is metered recharging stations at the employer's parking lot. An even better answer is to erect a PV panel over the metered parking spot to power the recharging meter, and to also shade the vehicle.

For a "standard" space 2.6m x 5.4m, adding 50% more area as a credit for extending halfway over the adjoining aisle, at 52 degrees latitude, and 4 peak sun hours per day, average expected energy is 187 MJ of sunlight, perhaps 37 MJ electrical. At 1.4 mm/J, this is 52 km!

Actually, since that's an annual average, the limit on practicality would probably be set by the winter minimum, but I don't know how to find that.

52 km is still considerably farther than I had expected.
