And there is no way anyone will install charging facilities in the parking area.

Leatherhead to Dungeness is 85 miles

Very easy to just drive there and back without charging in many (probably most) EVs on sale today.

Lets say you are in the far corner, Lightwater. That's about 100 miles each way which plenty of EVs can do without charging, but maybe not with a big kit-surfer contraption on the roof.

There are fast chargers en-route, so A better route planner recommends a 15min charge at the Maidstone ionity:

But the other 80% of your trips now involve never going to a petrol station - the car is always full in the morning. That's not really any worse, and an EV is _much_ nicer to drive than an ICE car (noise, nip, smell).

So yes. Obviously 'madness'. It'll never catch on.]]> Battery powered everything http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298140#Comment_298140 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298140#Comment_298140 Sun, 09 Oct 2022 11:24:25 +0100 WillInAberdeen
That's about 100miles per week on average. So many new electric cars will go for a fortnight or more on a charge.

The mental model of an EV needing to be kept overnight every night plugged into a charger, on a private driveway outside a house, is maybe open to change now. The alternative model is of a visit to a rapid charger once a week (or fortnight) somewhere convenient where you would be parking anyway - supermarket perhaps.

That requires more focus on rolling out rapid chargers and distribution network capacity to shared locations, so the majority of folks without private driveways can reliably get electric cars recharged.

They only have fast chargers, if they have anything at all. I suspect we need the next generation of chargers that include storage so they appear as continuous lowish loads on the network but provide intermittent rapid charging to cars.]]> Battery powered everything http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298142#Comment_298142 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298142#Comment_298142 Sun, 09 Oct 2022 12:15:21 +0100 djh Posted By: WillInAberdeenLast year, the average annual mileage was down to 5300 miles, which is about half what I had imagined.Yes, me too. The figures for 2020 and 2021 are probably reduced by covid (edit: there's a note on the spreadsheet that says so :). I also wonder how many households have multiple cars and whether there's any way to construct statistics for what I would call 'primary' cars? Or even statistics for the average number of cars per household and the mileage per household rather than mileage per vehicle?.]]> Battery powered everything http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298154#Comment_298154 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298154#Comment_298154 Sun, 09 Oct 2022 14:05:22 +0100 WillInAberdeen
True, but even before 2020 the average mileage had fallen below 150 miles per week, and it didn't rebound in 2021. Half of the 2020 drop was due to commuting mileage which isn't going to fully rebound IMO.

>>> households have multiple cars

Yes, that might well be a reason, more households have two cars. That's an opportunity as people can dip their toes by replacing their runabout with an EV for their short journeys, while building up confidence for their 200mile kitesurfing vehicle.

>>> supermarkets with rapid chargers

Morrisons near us have 50kW chargers AIUI, but as I said there needs more pushing. Storage would be good so they aren't adding to peak time loads.

Another edit: you have to pay for 50kW charging at Tesco, but 22kW is free apparently

I too am surprised mileage is down as far as 5300 (is that per driver or per vehicle or per owner?). It has been dropping for about 20 years now and was 8900 last time I looked. Hmm, but checking the data that was correct in 2005: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1101084/nts0901.ods and I thought that was the number for maybe 3 years ago. This may be the difference between driver mileage and vehicle mileage (similar number of drivers, quite a lot more vehicles, over that period).]]> Battery powered everything http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298168#Comment_298168 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298168#Comment_298168 Sun, 09 Oct 2022 20:22:28 +0100 djh Posted By: WillInAberdeenEdit : also Lidl

Hmm, YMMV as they say. Our local Lidl has no chargers at all, and the local Tesco has two 7 kW Pod Point units. For completeness the Aldi has 2 x 7 kW and the Asda has none. All chargers are free for customers. But I only ever used the Tesco for five minutes when my home charger was playing up, just to check which bit wasn't working.]]> Battery powered everything http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298170#Comment_298170 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17591&Focus=298170#Comment_298170 Sun, 09 Oct 2022 20:58:15 +0100 WillInAberdeen
For supermarkets the game will be to draw in drivers who need to recharge, who then buy groceries whilst they are there, same as with supermarket petrol stations. Rapid chargers have the advantage that the customer will recharge for just long enough to shop and then vacate the space, rather than parking for several hours.

Though it all
requires more focus
and
there needs more pushing

Anyone want a ALL charger and two batteries?To continue the continuation, Bosch replaced the strimmer a second time (both times failed within one year), and since then has performed perfectly - now a great favourite! I am pleased it has redeemed itself, as it's a radical, re-thought design, unlike any other, stylish, telescopic and folding at a touch. It lies next to my wife as she's gardening and gets picked up and used for a minute as readily as her trowel.

Having seen three brand new examples within two years, was interesting to see the design revisions, esp in the string spool - now much more robust. BTW, it just has a single string sticking out, and uses a special square-section string, but uses it up quite slowly, which is good in leaving less plastic for animals to choke on for the next 100yrs. The string can be bought cheapish online.]]>
