Even upping the voltage on electric-car chargers doesn’t mean that the time it takes to charge is comparable to the time it takes to fill up the gas tank of an internal combustion car. From Eric Peters at ericpetersautos.com:
Less is always more when it comes to electric vehicles.
The latest news is that doubling the voltage of commercial charging infrastructure – from 400 to 800 volts – will “reduce” the time it takes to instill a partial recharge to “only” about twice the time it takes to refuel a non-electric car to full.
Italicized to emphasize the usual dishonesty of presentation when it comes to “news” – always glorious! – about electric cars. In this case, the attempt to equate the time it takes to refuel most any non-electric car to full with the time it takes to put a partial charge in an electric car – using commercial infrastructure that doesn’t exist – without explaining to the marks that if you only get a partial charge, you’ll be recharging again and soon.
That means even if 800 volt charging facilities were hey, presto’d! into existence tomorrow, reducing the time it takes to partially recharge an EV to “just” 10 minutes, it would be the equivalent of putting a perhaps a quarter-tank of gas in a non-electric car (enough to go about 100 miles) which would take less than five minutes in the non-electric car.
