Precisely! That's what I learned after spending time creating a reasonably granular simulation. Everyone talks about energy. This allows for hand-wavy arguments that end-up being false. I am not claiming that people do this intentionally or maliciously, BTW. Until someone takes the time to truly understand the realities of widely deployed EV's, it is impossible for them to understand what the problem looks like at scale.
The hand-wavy statement usually takes the form of "just charge at night/work/off-peak", etc. What is not immediately obvious in this way of thinking is that this isn't at all a solution. It's hard to think in terms of aggregate demand.
No matter how you charge, slow, fast, distributed across the day/week, etc. At the end of the day, what you discover is that there's an unavoidable steady-state power generation and delivery requirement. Energy is power spread over time. Energy is great, but it does not address the needs this second, or the next. That's power. And that's the issue.
Not sure I provided this link before. I ended-up confirming my estimate many years after I came to this conclusion when someone finally asked Elon Musk the question. Here's his answer:
