It looks like the results presented here are based on a simulation model. Displayed on the third page[1] of the paper is a diagram illustrating that the number of voltage violations remains relatively low from 0 through 5000, 10000, 15000, 20000 and 25000 heavy-duty vehicles simultaneously being charged. Then as we approach 30000 vehicles (and continue beyond), the number of voltage violations increases markedly. Can anyone provide supporting information on what "voltage violations" are and how serious these are, and/or any theories about why there is a sudden increase in the number of them…

"...we find that as little as 11% of heavy duty vehicles in Texas charging simultaneously can lead to significant voltage violations on the transmission network that compromise grid reliability. Furthermore, we find that just a few dozen EVs charging simultaneously can lead to voltage violations at the distribution level..." https://arxiv.org/pdf/2203.04430.pdf
