600 KW is some chunky wattage. It's unlikely you can charge very many cars at the same time without having a power station next door. Delivering, for example, 10 megawatts to handle 15 cars simultaneously, requires some very heavy electrical and safety engineering, which would be very costly. You could run pylons along the highway, but then you'll need an high-wattage electricity substation next to each charging forecourt to bring the voltage down. A gas fuel tank under a service station, however, is cheap, and is limited only by the size of the forecourt in how many cars it can simultaneously service. And we still have the problem of charging time. You'd probably talking a forecourt capable of charging 100-200 cars simultaneously during peak times. That's 60-120 megawatts on Musk's fast charge. That's enormous. It's an entire small power station. For any long distance, my sense is that electric cars are still at a heavy disadvantage to the ICE for the foreseeable future, even assuming Musk's optimistic charging cycle projections. Let's face it, gasoline still has some miraculous energy storage density / transportability advantages.
