50 to 200 kettles? That’s wildly off. A typical kitchen water-boiler uses 1.5kW. My EV, when charging at home, charges at 5kW. If you have to do a fast charge

50 to 200 kettles? That’s wildly off.
A typical kitchen water-boiler uses 1.5kW. My EV, when charging at home, charges at 5kW.
If you have to do a fast charge because you’re on a road trip, you might choose to accelerate battery degradation by charging at 50-200kW, but that’s the rare and expensive exception to the rule.
What’s hard about national events is that historically power generation hasn’t been good at load following. If you know you’re going to charge 2 million EVs every night, there’s very little load following needed, it’s a steady load.
It’s still a lot more energy than current grids can supply, so there’s no doubt that more production and transmission is needed, but the engineering to achieve this is not some radical departure from current techniques.
- mrtksn 4y agoReally? Are fast charger use an exception? If so, why people make a big deal of Tesla's charging network? What about people who don't live in detached private houses? Are they exception too?
- fomine3 4y agoSupercharger should be considered as a exceptional method to charge, but people focus on it.
- mercutio2 4y agoOnce or twice a year, when we go on a long road trip, it’s a great sense of security to have superchargers everywhere. Fast chargers for other vehicles or much more unevenly distributed, and they’re liable to just not work half the time. But all of this only matter when we’re driving more than 200 miles from home, or doing a day trip somewhere more than 150 miles. Which for my family is just not very frequent.
