I'm unsure how it works (Beosoaker3 can likely shed light) but here is a recent article on EVs and the UK
The government of the United Kingdom is already starting to plan for power shortages caused by the charging of thousands of EVs. Starting in June 2022, the government will restrict the time of day you can charge your EV battery. To do this, they will employ smart meters that are programmed to automatically switch off EV charging in peak times to avoid potential blackouts.
In particular, the latest UK chargers will be pre-set to not function during 9-hours of peak loads, from 8 am to 11 am (3-hours), and 4 pm to 10 pm (6-hours). Unbelievably, the UK technology decides when and if an EV can be charged, and even allows EV batteries to be drained into the UK grid if required.
