Electric cars wont rival gas powered cars until charging can be done as fast as filling up a gas vehicle. A 2 port fast charger is over 60KW. Your home with a 200a circuit breaker for 240v has 48K of available power. The current at home charger takes several hours to charge a car. Consider that every home with 2 electric cars will need at least a 400a service if we stay with 240v to even come close to making home charging EV's as convenient as gas powered cars or we'll need multi port charging stations capable of charging in 15 minutes or preferably less. Either way, the electrical grid and transmission equipment needs a major overhaul AND the power supply needs to increase greatly. Just look up how many cars are in california and calculate how much power charging them will require. Its surprising. More like shocking.
