I think I have a different take on the subject since my background is nuclear power and electric generation. Video if you have Fakebook: https://fb.watch/pAd2AOu4ZO/. Guy was charging an EV, consuming 137 KW (137,000 watts), the average home uses 1.25 KWh, so he was taking the same power that 106 homes would use. If he could charge at the full 350 KW would equal 280 homes. Now if every home suddenly needed to charge an EV every day, and considering the grid hasn't been significantly changed in half a century, there is no way the grid could support a large number of EVs. Seriously, CA had to tell EV owners not to charge their cars last Summer to protect their grid. Just my humble opinion, your mileage may vary.
