For local commuting (20-60miles/day), charging is not a big issue. Even with a 15amp household outlet, you can let it trickle charge for 10-16hr at night and should work.
For long distance travel, it's an issue. To some degree it's a question of building more but a high speed charging stall (one stall not the entire station) can run $75-150k. Even with fast charging, you will need 3-4 times as many stalls to service the same number of vehicles due to the time it takes to charge...so the EV equivalent of a small 10 gas pump station, might be $3-4million just for the chargers (the minimarket, drives, etc... are all extra).
If you get into larger stations or remote non-urban stations, the prices can increase exponentially as the power grid feeding them needs to be upgraded up stream.
Also, expect high speed charging station costs to increase dramatically once the govt gets out of the subsidy business.
Towing with an EV is mostly a demonstration project.
