These "impact on the grid" scenarios never come to fruition, simply because every possible impact has not only been envisioned by the person doing the warning but also has been anticipated by the engineers who design and build and operate the grid. The grid evolves every day. Just ten years ago they said the grid could not handle more than 10% solar/wind, but now many countreis have seen days of 100% renewables on some days and the grid held up just fine.
The "GRID" is a moving and living thing. Every new demand is a new opportunity for someone to innovate, and that innovation is running at a feverish pitch. By the time there are enough EV's to have even the slightest impact we will also see all kinds of grid interaction systems balancing in real time and paying whatever it takes to meet demand, and those with home or grid batteries will be happy to sell. and or shift demand, etc. So don't worry about it!
