Charging a Tesla at a supercharger is even easier than using a petrol pump. Don't even need a card or need to swipe anything at all. You just plug it in and it works.
Not just Tesla's if you use Fastned it has a feature called Autocharge which is compatible with most CCS based vehicles. Gridserve are rolling out a similar feature that is being tested at the moment.
Only if you've already stumped up for a Tesla
us plebs can use some of the superchargers but need to claim the charge through the app.But as is already pointed out, @Nasher is speaking total rubbish - there's next to no chargers that need apps anymore, they're all contactless.

The above are concepts, the EV is the present.
The reason hydrogen int coming though for passenger cars is purely economic.
Hydrogen is more expensive than petrol and diesel and it doesn’t even have any tax added.
Green hydrogen will always cost 6X+ of just filling a battery because that’s how much electric you will lose to make, compress and transport it.
It’s just a pipe dream that there will be abundant ‘green’ energy floating around to make it. For a start our generation capacity is actually shrinking BG in the short term and the millions of battery equipped vehicles on the road will be sucking all that up themselves and the rest will be sold to the continent who don’t have any wind.

Stranded electric generation. Easier to move hydrogen than electrons

The only real benefit is if we really have an excess we can ship and sell it to other countries, ie countries who need to meet Paris 2050 carbon commitments but don’t have the geography for significant renewables or nukes… Japan case in point.
Also for payload carrying vehicles means you do have more capacity as the mass doesn’t have as much dedicated to propulsion as oppose to cargo.
Hydrogen absolutely has its place, for example, in heavy plant where there isn’t a readily available electric supply like road building.
But for passenger cars which on average spend 90% of their lives parked within meters of an electric supply, it just makes zero sense (that’s not to say somethings don’t need to be built to tap into said electric supply, but it doesn’t change the fact it’s already there).
Since when? The electricity transmission network already exists and we are building huge interconnects across the sea to every neighbouring country to import and export electricity.
Hydrogen is easier to store, that’s its main advantage but it comes at a 6X efficiency loss.

Maybe further than neighbouring countries then… or even more remote islands; and of course there will be limits anyway to the capcacity of said interconnects.
I can't refuel a hydrogen car from my excess solar generation, and I can't then power my house again from the excess generation that was stored in my car battery. Sorry, why is hydrogen better for passenger vehicles?
Trucks, trains, plant machinery, long distance busses, ferries/ships and the like great, but normal passenger cars not so much.
Same argument again and again, its like people don't do any research and just assume as if is filled up fast in a similar meth that they are used to then it is better, with literally no clue as the obstacles in place to get that same 'feeling' not to mention how much energy it costs to produce the stuff in the first place.

Some home charging news which I missed
From June 30th, every new EV charger that is sold will have to include a ‘random delay’ of up to 10 minutes every time an EV starts to charge.

That's what grid battery storage is for
So... at most losing out on about 1kWh of charging at your cheap rate right? Seems sensible to avoid everyone starting a charge at 00.30 exactly and the grid having a spike.
I don't see why stopping would have a delay on it. There's no grid implication for that.
There is an implication for that, generation need to ramp down very quickly to stop there being an over supply.
In reality most cars will stop charging well before the end of the 4 hour period anyway but what’s even more likely is that systems like Octopus intelegent will become mandatory or not using that system will cost £lol.
Intelligent basically makes a bespoke charging schedule for your car. You tell them when you need to charge and by how much and they add electricity to your car when electricity is most abundant, cheapest, or at its lowest carbon intensity.
Only smart chargers. I have a dumb charger that does allow delayed charge up to 6 hours.
So i could plug in at 6pm and it would start at midnight.

The override control is far more relevant to the smart EVSE regulations.
I’m waiting for the update on my OHME app that allows you to turn this off anyway. My timed charging already satisfies what the regulations are sensibly trying to do. One of energy management and then this time delay to plateau inrush power demand.
