So you'll have to build and bring online a whole new set of power plants in place of all those refineries then.
I think this is definitely a very large issue and no trivial undertaking.
- theshrike79 5y agoWe've got a good 15-20 years before EV density becomes an issue in most countries. Japan, with their 1-phase 110V network won't be converting to EVs soon. But here in the Nordics pretty much every house has 3-phase 230V and already wired for electric saunas and multi-kilowatt heaters. Adding a plug to charge an EV is a non-issue.
- fomine3 5y agoTo be precise, most houses in Japan pull 3 power lines (-100V, 0V, 100V) so they also supports 1-phase 200V by using -100V, 100V pair. Another problem is electric company offers only 6kVA max for normal family plan. If I need more capacity, monthly bill isn't getting much higher, but selectable plan is limited and I should pay replacement cost at once.
- Tor3 5y agoSeveral years ago there were already more electric charging stations in Japan than there were gasoline pumps (of which there are many!). When I heard that I was very surprised because I hadn't noticed any. So I started looking, and yes they're there - just not so easy to spot. For some reason the ones in my own country are very visible, they are flashy and with lots of lights and big signs. The 100V (not 110V) network in Japan is indeed a lot of trouble for a lot of things, but it doesn't seem to be a hindrance for EV. It's just that it may not be as many home chargers there as in e.g. the Nordic countries.
