Nobody is arguing that we don't need a very large number of Level 2 chargers. Level 2 chargers are not what is holding back the sale of EVs. Period.No, we don't. As DC fast chargers are not the only way to "fuel-up" an EV.
What we need is hundreds of thousands of L2 EVSEs. And amazingly most EVs come with one. (Tesla being an exception.) And the BIL funding is planning to put in ~450k L2 EVSEs where people need them most: Apartments, businesses, shopping malls, parks, etc. And lots of states/utilities have incentives for people to install a L2 EVSE at home.
Level 2 charging is a much easier problem for the consumer to manage because, with few exceptions, people can install a charger at home and there are already state, local, and federal incentives to do so.
In order to scale EV adoption you must satisfy the fears of the average consumer who worries they won't find a charger when they are on a road trip. Even though most people drive most of their miles locally, that doesn't translate to rational human behavior.
We judge the viability of our transportation on whether or not we are likely to be stranded on a roadtrip that amounts to 10 percent or less of our total driving.
If you look at polls of people who are afraid to buy an EV the main reason is cost and reliability and availability of charging. Cost will come down as we scale, but the network must be reliable, ubiquitous, and reasonably fast.
That requires, at a minimum tens of thousands of DC fast chargers in order for most Americans to feel "safe" leaving for a road trip. Likely more.
That's human psychology 101.
