The batteries store power in watt energy. A typical EV battery will charge up with enough energy to run the typical home for two days. The Tesla Model S and Model X variants holds 100 kWh and with quick charge 220 VAC system, For the Model S Tesla, it only takes about one hour to charge to 100% if it were totally depleted (not the usual case). That means, enough power to run a home (30 kWh per day) for three days is consumed in the 1 hour to charge it. That will put a huge demand on the energy infrastructure necessary to support it. I can imagine the transmission lines will have wire conductors the thickness of three inches to carry the power and power transformers on every other drop.

All connections will have to be solid or the resistance will cause enough heat to melt the connectors.

Great diagram. Here are a couple of voltages to go with it. Generators at the plant produce 18,000 volts. This is stepped up to typically 750,000 volts for the transmission lines. At the substation the 750,000 is stepped down to (typically) 23,000 volts for the distribution network, and the pole transformer steps the 23kv down to 220 volts that we have in our houses. The power loss from plant to house averages 8% although this can vary as you pointed out depending on the state of the transmission and distribution network and also on the current demand with heating due to high current slightly increasing the resistance of the system.

Good analysis. I never considered the total amount of electrical energy that would have to be produced if all of our vehicles were battery powered.
