So you are saying it is the hose that is not designed correctly to deliver 100% output irrespective of the fullness of the pool?

A battery isn't a swimming pool.
I'm not the one who made a swimming pool analogy! I'm just playing that analogy through to the endA battery isn't a swimming pool.
Why? Are you actually confused, or just trolling?I'm not the one who made a swimming pool analogy! I'm just playing that analogy through to the end
If you need an analagy - use Elons.

It would if the connection was at the bottom of the pool and so affected by the pressure of the water above the discharge point
My lights haven't failed to turn on yet
Hah! I was waiting for someone to use that one on me.It would if the connection was at the bottom of the pool and so affected by the pressure of the water above the discharge point
I guess they need to make sure they connect batteries from the top and not the bottom of the pack
Good, so we have established we don't have an electricity shortage - so that means there is no need to ration car charging, and we can allow everyone to fill to 100% without any penalty.
Just getting his MM contribution in for the next few months
Had a good trip over the Xmas break. 300 miles each way up and down the M2/M25/M1/M6. Pretty effortless in the Q8. Stopped as late as possible on the way up so I'd arrive with plenty of charge left. Made it 196 miles up to Corley services on the M6 with plenty to spare.
On the way back stopped at Watford gap. Car charged so quick on the high power Gridserver chargers, I had to go move it off the chargers to a normal space before the family had finished eating lunch.

I'm playing devil's advocate to force people to see how silly this idea of "charging more to charge above xx%" is.
Done that on 30th December already, so I'm safe until late MarchJust getting his MM contribution in for the next few months

What we very occasionally have (so infrequently here, that the charges we're discussing don't actually happen here afaik) is shortage of rapid charging capacity, so systems exist to enable "rationing" of rapid charging at peak times of congestion.
For the other 99% of the time when it's not an issue at all, everyone has more capacity to charge as they see fit.
It's not though. I'd be totally happy with that during perioids of high demand, or specific to high power chargers.
I'd consider most EV drivers as being more considerate than average to others. However there's still a subset of EV drivers who are absolute tools that would happily block a charger at their leisure.

What is the cause of this "shortage of rapid chargers"?
Is it a genuine shortage - where no ability to expand the network exists due to a lack of materials or similar.
Or is this a shortage caused by underinvestment and over-profiteering?

It's caused (typically) by a very brief concentration of demand on the infrastructure that is otherwise of more than adequate capacity for 99% of the time.
You don't build 50 rapid chargers and provide massive local electricity generation /distribution to cater to a couple of demand peaks per year, the same way we don't build 10 lane motorways just to cope with the Christmas travel rush. You encourage people to use the normally adequate infrastructure in the most effective way possible, in this case, encouraging people to charge a couple of times very fast rather than once but slower overall.
I've not experienced a shortage for many years. I've only ever had to wait to charge twice since 2016. Things are much better now than they've ever been. Modern EV/changers can add 200 mile range in less time than it took to add 30 to a PHEV in 2016. Most major charge locations have 10+ chargers now instead of the 2 they used to have.
Shortages are due to spikes in demand, like with public transport. At 7am on a weekday all our local trains are rammed, then the rest of the day and at weekends they're virtually empty.

Thing is ... petrol stations would have the same sort of "peak demand" requirements, however they don't penalise you for fully filling your car during let's say Christmas.
The cost to the provider to charge or fill up does not change during this peak periods, as it's all based on pre-locked in wholesale rates.
So charging more is just a mechanism to make more profit.
If you have a ‘limited’ supply capacity. And your chargers are all full with people charging to 100% with people waiting it’s both less profitable and more frustrating for the users
By kicking people off at 90% then the operator can sell more energy (higher average kW hence more kWh sold) and reduce congestion ( isn’t this the telsa UsP having chargers always available)
They’re is nothing worse than rocking up to chargers you need and having to wait to start charging. Then have to wait again whilst it charges. So limiting people to 90% is a sensible idea based on real world rather than utopia.
Don’t know why people care tbh. 90-100 take ages anyway so it’s just being stubborn sitting there to 100% if there are people waiting. Bit like the idiots who leave their car at the petrol pump when doing their weekly shop inside the forecourt store

It's not, it's primarily a mechanism to encourage efficient and effective use of available infrastructure.
Given you're normally charged per kWh, even at inflated rates, they're probably seeing less income from someone trickling that last 10kWh in than the next person being able to dump 50kWh into their car in the equivalent time.

So the problem is that demand for chargers is greater than the supply.
There are 2 ways to fix this...
(1) Increase prices to drive down demand, and increase your profits with 0 additional investments.
(2) Increase supply by building more chargers, which requires investment.
I disagree with (1) being the route that's followed, however it sounds like everyone else in this thread is happy for that to be the way forward.
But that "trickle charge" mechanism is exactly how they (the car company) designed their product.
If they didn't want people to trickle charge, then why design the car so that it needs to have that last 10% to be trickle charged?
