Not as far as I know I don't, I've never claimed such.
Most of Britain's renewables are wind based, one of the things about wind is it still blows at night which causes issues.
Charging cars at night is a great thing because it uses power which otherwise wouldn't get used and prevents the cost of shutting generators down.
In fact the problem you have is you're talking about our energy mix as an average, charge at night and that energy mix doesn't apply in the same way, in fact the reason the prices are so low is because they can't usually give the stuff away.
Ultimately storing surplus energy to move vehicles around is a good thing right? I'm sure you'll agree.
The whole lithium battery thing is somewhat overplayed these days often based on 10 year old surveys and tech.
Some of the worst offending metals like cobalt have fairly low percentages - well below mobile phones, rechargeable tools along with their 'non-recoverable' use in refining fuel for IC engined cars.
There's a lot of movement on recycling car batteries - you'd be mad not too, 200kg or so all in one place? Last I saw some of the commercial plants where hitting 95% recovery rates.
So of course EV's are not carbon neutral, but over their lifetime they're a lot better than IC cars.
In truth nothing we consume is carbon neutral - not even bicycles.

If you can run your vehicle on them, on a small scale basis great but I doubt the capacity of a stand alone installation for most peoples 6-10k miles per annum.
10,000 miles a year is about 2.5MW. A 4Kw system typically produces 3.5MW a year. (And the trend is for bigger (6.5Kw) systems and battery storage to soak up any surplus).
Obviously in the winter things are less good but overall private solar makes a pretty big dent in electricity usage - and it's fairly predictable too which is something energy companies love.
Losses on transporting electricity are significantly less than transporting oil or gas.
They can also be reduced. China for example is building 1MV power lines to move power around the country at reduced losses.
We already import electricity from other countries so nothing new is needed.
Ultimately though losses are merely a number, they can be gotten around by adding more solar panels or wind turbines. Somewhere in the world there is wind and sun to be harvested.

The important bit in that statement is "IMV". The national grid says they can cope, most EV's charge overnight (and infrequently at that) when the grid has a problem with surplus.
EV sales are the only thing that's continuing to climb against a general decline in car sales.
IMO they're very close to a tipping point particularly as most folk buy cars on PCP and if you include the running costs they simply cost less per month to own and run.
Throw in the company car incentives for BEV's and for a lot of folk they're a no brainer.
They've still got a fight on their hands, some folk resist any change and look for reasons not to engage.
But in the end more money in folks wallets will always win.
