Another way would be to add the road use tax to the charging networks, proportionately (which, although it’s 5th grade math, isn’t hard even for politicians to figure out).
I bet it is too hard for some politicians to figure out. But one of their un-named office assistants with a high-school diploma could certainly do it, if asked.

But a number of the EV proponents are continually telling us that a MAJOR benefit is that you plug in your car at home and avoid public charging networks altogether.
I Recall WEB relating that some politicians wanted to change the value of pi because it was an irrational number. Unreal! 
Currently there’s tax credit up to $7500 for EV that would offset any extra tax.
“Currently there’s tax credit up to $7500 for EV that would offset any extra tax.”
For some EVs. Tesla and GM cars no longer qualify. Ours didn’t, but no matter.
