The Tesla semi is supposed to have a 900kWh battery, so even at the full 1.2MW delivery, it will still take 45 minutes to fully charge its battery. Assuming that, to preserve battery life, it's charged only to 80%, and recharged when between 10% and 20%, that's a half hour at the charging station. A large truck stop on an interstate can have 15 to 20 fuel pumps, with a fillup taking 10-15 minutes; that makes a recharge 2x - 3x the time to fill up with diesel (unless the jerk in front of you has gone in to take a dump or a shower while their truck is sitting at the pump). Now assume that the electric truck stop has 20 charging stations and a 10MW power feed; if it's full up, you're only getting 500kW; that pushes your charging time to 60-75 minutes.
