    I find your quote re EV battery longevity slightly understated Simon. My VW is battery is guaranteed for 8 years, I take that as they would last significantly much longer otherwise it wouldn’t be cost effective for them to guarantee them .

    The next interesting step will be charge your car overnight on cheap tariffs and power your house from the car battery during the day….That would be amazing.

    Some of the batteries currently in development have a claimed range of over a million miles, I don't think the recharge time for one of those is going to be a major issue.

    Not interested in the Beamer that’s a luxury car and the most untypical electric car you could have chosen. To suit a nonsensical argument perhaps.

    I assume you own an EV to make such a bold statement?

    I have a family EV, 5 seater in comfort , does 260 miles on a full charge in summer and beats most petrol cars on the road at 0-60 in 5.8 seconds

    November 2021 running costs

    All data recorded and available . I don’t have solar and all juice from the National grid.

    Total mileage 1,241, Approx 50% at 70 mph
    Total charging cost . (100% at home and no free public charging) £23.68. 1% added to the charge takes about 4.8 minutes, 10% 48 mins and so on

    1.9p a mile

    So far from a gimmick these are day to day running costs over a month last autumn from a real owner not an 18 year old journalist writing for the Daily Express .

    Like to share your Petrol / Diesel fuel costs over 1200 miles to see where the gimmick lies?

    I’m more than interested!

    As far as I’m aware all EV batteries degrade their most in the first year, some more than others depending on how they are charged. . It’s battery chemistry and charging procedure. High DC charging at public chargers degrades batteries at a far higher rate than home AC charging . My car battery is preserved longer by 100% AC charging , keeping it in the State of Charge region of 20%-80% . It is recommended you charge to 100% once a month and don’t let it stand at 100% for long periods after charging. Hope that explains?

    Your charging time is where it all starts to fall down, it’s totally impractical. I’ve got a 2020 BMW 320d and does about 40mpg but vast amount of that is city driving. Of course you will beat me on cost per mile. My argument is initial cost, practicality and servicing. Most of the EV purchase prices are pricing people out. The practical side, takes 3 mins to fill my car up, takes hours and hours for an EV, the infrastructure is not readily available and is slow. Servicing, you’re not telling me with the amount of torque an electric car has that you won’t be ripping through tyres for fun? Oh and forgot more costs, the insane insurance quotes. Look to get a Tesla in a fairly nice part of Leeds, just under a grand. My beemer is £410. I’d say in five years it might start to be more affordable and more practical for the normal working person, but at the moment it’s still very much work in progress and expensive.

    Not sure how much solid-state batteries really save on rare-earth elements. Maybe they do and they just aren't talking about that side but the main driving force with them is more the safety (they are less likely to explode although I believe they are still very combustible if they catch fire) and the fact they can produce the same power in a smaller and lighter size so they can either have less space taken up by batteries which helps make the cars lighter or they can take the same space and get more power or range. I believe also it is more recyclable, things like the safety issue mean that so little of an old battery can currently be recycled for other use and the bits that can have such little value compared to the cost of doing so that it’s largely deemed not worth doing. As it’s safer, more of the solid state battery should be viable to recycle as the costs of doing so are lower due to that (or will be at some point)

    So we most likely need something more than just this this step to solid state to really make it more environmentally friendly. We need something that allows for everyone to switch to EV but where are earth elements are either so low or non-existent that to support the number of batteries needed, not just for cars but for everything with batteries in without having a major ecological crisis to support it

    I suspect that that has more to do with the kind of buyers. Avid drivers aren’t buying things like the Zoe, even if they abide by good practice and keep the battery above 20% I suspect most most of their customers aren’t charging it more than once a week. 52 charges a year puts you around the kind of number of charges across 8 years that the mileage guarantee gives. As such the risk of increasing it to help sell more by giving people peace of mind will likely offset the small number who buy it and either work in a job with lots of driving or just enjoy driving a lot. It’s the benefit of doing their figures in years and miles rather than charges, your phone or laptop can only give a figure in number of charges, they can’t increase their number based on average users use because a charge is a charge but a yearly figure can if users charge less often than expected.

    First service due after two years, UNLIMITED mileage Cost £170
    Brakes one check at 150,000 miles
    I have my own 7.2kw charger on my drive, I don’t need to queue and it charges when I’m asleep. So ZERO inconvenience.
    My car has covered 7k miles and worn less than 1mm tread.
    On board technology prevents wheel spin, I haven’t spun it once. And I drive faster than most.
    It cost LESS to insure than my 18 plate TRoC did costing £10k LESS. ( Too many automatic safety systems on board )
    It isn’t a Tesla, which is an overpriced US car and poorly built

    All your comments, born out assumptions and mis-information, clearly, negated with facts.

    Boris asks the chancellor we need £100billion for future nuclear power stations for energy security, Rishi has told him no he will not spend the money needed, Will we ever get our national energy needs right?

    I have had a plug in hybrid for nearly 3 years now. It's ok. Claims 41 miles on a full charge and most I have ever managed is 20 driving with the touch of a butterfly. The transition between the 2 drive modes can be clunky and unpleasant. Not sure which way I will go next. It has always surprised me no one has made an EV with a tiny supplementary petrol engine, say 300cc and 40mph. Just enough to rake away the anxiety of being stranded out of charge.
    However if you haven't already done so google Trevor Jackson and his aluminium ion batteries. When I last heard him on the radio he reckoned his technology was about ready but the contractual obligations of the big car companies to the lithium battery manufacturers was holding him back. Tbh I don't know how close it is to reality but see if you can find the vudeo of him drinking the electrolyte out of one of his batteries to prove it's safe

    Electric vehicles are the future. But with that will come problems just like any form of technology. It's a great option for people who can afford it but as the second hand car market shows, most working class people and those from poorer backgrounds simply cannot afford to go out and a purchase a new vehicle. Most rely on the second hand market and im waiting to see what the market for second hand electric vehicles look like in say 5 to 10 years time when maintenance costs start to kick in and batteries start to fail. Worryingly for me I can see poorer people being priced out of owning a vehicle.

    I will stay with petrol as long as an option, my Dacia does 50mpg has all the tech needed and is cheap to insure and service, I will change but to early as technology still evolving between batteries and hydrogen fuel cell or direct hydrogen combustion using virtually the same engine as petrol but with only water through exhaust,

    I'm guessing something may have changed in the last week or so, but a couple of weeks ago the CEO of Quadrilla was on the radio saying that despite what some ministers and others were saying in the media, his company had received no contact whatsoever and were still under directive to cap the existing wells

    Haven't they just had the deadline for capping extended rather than uncap anything? The moratorium on actually using them is still in place

    Not sure the CEO seemed to be saying on news this morning they had been given permission to explore further on 3 sites
