A ten-fold increase in range means a ten-fold increase in charging time.
Or the mobile nuclear reactor charges tour house/car once a month. Well then it might make more sense to install a small modular reactor every so far.
I am no EV fan.
However charging time is about the only thing that’s improving with EVs. If they can handle a high rate of charge it might not take as long as you’d think
That said getting that high rate to a charging station will be challenging
There could be an improvement in charging efficiency (reduction in thermal loss), but not a huge amount.
