I recently read through this and was just curious what others thought the pitfalls or unforseen issues might be with quickly or steadily transitioning to such in a fairly environmentally friendly manner.
Hate the title name, but I think I have to use the article title as the title.
Taking this at face value, I note two things:
As for point 1, the power has to come from somewhere, and our current power grid is already having problems keeping up with current charging currents, and if a battery like this will be able to get charged 80% in 9 min, to use it you have to have a power source to supply that ammount of power in that time.
This could possibly be mitigated somewhat with huge batteries at the charge station that get charged slowly over time and that is then used to boost the charging of the car, but this would need specialized maintenance and commes with big potential risks.
As for point 2, the huge ammounts of power being delivered to the car will require a perfect connection between the power source and the car, it will require heavy insulation in and around the car, I wouldn’t want to be within 10 meters of the car while charging due to potential risk of arc flash.
It’s not such as impressive amount of power compared to existing installations. Say 75 kWh battery. 80% of that would be 60 kWh, charged over 9 minutes. That’s a 400 kW charger. Meanwhile 300 kW are reasonable common and there are a few 500 kW chargers out there. A 500 kW charger would charge the car to 80% in 7 minutes.
Thanks for giving me actual numbers, that makes it sound less insane.
