The only way EVs become truly practical is with standardized battery packs and battery swap stations. Sure you can overnight charge your EV at home, but any travel you need to pull into the station and have the robotic system remove your depleted batteries from under the vehicle and replace them with fully charged ones. In and out in under 10 min just like a conventional liquid fueling.
This also eliminates the headaches of battery replacement / life as well since that is absorbed into the overall system. This is a very well established principle, it's what we have been doing with our welding gas cylinders for decades. We don't deal with 10yr hydrotest or waiting for a fill, we just drop off our (owned) cylinder and pickup a full one. We own a cylinder, just not a specific one, and we can readily do the exchange at different dealers as well without hassles.
This system does exist for EVs, China is pushing it a bit, but it needs to be fully standardized and widespread. Same battery packs for all vehicles, just different numbers i.e. 1 pack for a small car, 2 for a larger, 3 for a pickup, 6 for a semi, etc.
As for the power grid, distributed generation is the key there, don't try to transmit the power too far, generate locally. Solar PV on all rooftops, wind farms where viable, hydro / tidal where viable and the key - micro-nukes to fill in all the gaps. All green and all relatively locally generated to power the charging in the local area.
It will take time to get to that point, but that is where we need to end up if we want to go "green". The problem of course is the lack of clear leadership with a realistic vision of where we need to end up and the rational steps to get there, not pie-in-the-sky dreams and arbitrary and unrealistic dates.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
