Re: 350kW!!!!
If the frequency drops past 49.5Hz limit ( 1%) , they drop entire sections of the grid off completely until balance is regained
No they don't. The "demand response" doesn't kick in until 48.8Hz in the UK - see documents I linked elsewhere. "Frequency response" - where additional generating resources (generally fast ones like huge battery farms or pumped storage) kick in automatically - starts at 49.5Hz, but the intention of the grid operator is to avoid these automatic interventions and predict demand so that they can bring additional generation - more conventional sources such as gas or coal plants - online in time to meet demand. If a pattern emerges of large grid demands around 7pm when commuting owners of EVs plug them in to charge, the grid operator will learn this and will have plant "ready to go".
The point though is that although this is the way the grid currently operates, it isn't sustainable in the situation where there are millions of vehicles all needing (let's be generous) 15 - 30kWh of top up every evening. In those circumstances vehicle chargers will need to be intelligent and - crucially - will need to co-ordinate with the grid operator to delay charging or to charge at a slower rate to avoid unsustainable peaks in demand.
