I'm sure this has been discussed on this thread but I found it fascinating when speaking with an electrical engineer, who specialises in EV wall boxes, that the government/power companies can limit (control) the amount of power going to the wall boxes. He explained how it was done but part of it was lost due to the technicality of his explanation and the other part due to us being in a noisy environment; however, the gist I got was it was in place to help the government 'manage' power should their be shortages / times of crisis. The upshot seemed to be that they could turn power off to EV wall boxes, should they deem it necessary.
As I said, probably already discussed on here but not something I was aware of prior to the chat but made sense, if feeling a little too intrusive.
