    Tesco don’t give away petrol but frequently gave 5p a litre off vouchers which for my motorhome is worth about £3.50 compared to around 35p of electricity if you spend an hour shopping there. I usually top up at Tesco if there is a space and it just about covers the round trip. 
    Are the Tesco chargers not 7kw, therefore 7 x 35p = £2.45 per hour ?

    Most people shop at their local Tesco so if they didn’t charge at Tesco they would charge at home. On Octopus Go 7kWh = 35p

    Right. Was assuming you were comparing to other public chargers.

    I've never seen a charger at Tesco, or any other supermarket for that matter.  The only retail venues where I have seen EV charging is Costco and Westfield centres.

    Granted, not every store has them yet but most of the bigger stores do.
    If you download the Pod Point app, you'll see them displayed on the map. Some Lidl stores have chargers too.
    We have 5 stores with chargers within 10 miles.

    Tesla Model 3/1500 miles/24 hours


    Interesting video on real world winter economy (368wh/mile) and the impact of battery preheating.

    Also interesting comments including someone who had recorded charging losses over 3200 miles - 299kWh added 253 kWh to the car. Loss 15.4%


    https://youtu.be/oahH8xdoOVE


    We had an id4 77kh for a couple of days for a trip over the hols, total about 500 miles in 2 days - 5 degrees, not that windy, dry, less use of heating than ideal and we drove pretty conservatively (leaf owner!) and got about 3 miles per kwh (225 miles) which personally I found disappointing, driven at motorway speeds (mid 70s) and with rain and I suspect range would be about 150-170 compared to wtlp of 322 :(
    I think....

    That charging brand seems to have poor coverage where I am - nearest is at VW dealership 3 miles away.  They have 10 points (5 pairs) installed there - possibly linked to the range of VW ID EV's .

    Typical clickbait article in The Sun describing how their reporter drove a Tesla for a week, didn't bother charging it and nearly ran out of charge on the motorway!
      
    https://www.thesun.co.uk/motors/17107726/electric-car-tesla-week-review/

    An article describing how someone drove a petrol car for a week, didn't bother putting any fuel in it and nearly ran out of petrol on the motorway probably wouldn't generate as much interest :D  
    Yes it’s a click bait headline but the article is more balanced.

    “I'd always been pretty sceptical on electric cars - mostly because I have the same concerns about costs and charging as everyone else.

    A week with this Tesla very nearly converted me though.

    Out for a drive with my husband, I started speculating about whether an EV could be in our future, with their smooth driving and no gear changes to worry about.

    And then it was time to charge up.

    Even if I hadn't left it until the battery was near empty, I would still have had to tour around three different charging stations to find a working one or make a major diversion to the nearest Tesla supercharge point.”

    That pretty much sums up my experience of 2 years of electric car ownership. So much better to drive and perfect if you only charge up at home (so much more relaxing than standing in the cold at a petrol pump) but you just can’t rely on turning up at a charger and finding it unoccupied and working (unless you have a Tesla).

    I was coming back from Manchester Airport the weekend before Christmas and was unable to get a charge at either of the two motorway service stations I tried and had to leave the motorway to get a top up to get home. Fortunately I had a passenger who could work ZapMap while I drove.

    In the survey I referenced a couple of posts earlier, 46% of EV owners haven’t made a journey of over 200 miles and so a significant number of EV owners have probably never needed to charge at a public charger. I don’t doubt that the majority of EV drivers are overall happy with the experience but it isn’t perfect yet. When chatting at a charging point someone asked me if I would ever go back to a non electric car. I answered that a year ago, if someone had asked me, it would have been a definite no but now I’m not quite so sure. As EV penetration reaches past the first adopters and enthusiasts to those who are obliged to move to EVs (because of either national or local sanctions - tax, prohibitions and penalties) satisfaction levels are likely to fall. I am all in favour of EVs but more needs to be done to make using them more convenient. It’s easy to sell any new policy to those who support it (most of us on this forum) but less so to those who are negatively impacted by it and they can’t be ignored.

    The writer in the Sun drove a Tesla and apparently only used GeniePoint Mobile.  Not much research there then!

    In our experience it is rare to allow the EV below 30 - 40% and regular top ups are most likely.  Not common when we had an ICE.  Tescos  don't give away a free litre of unleaded when you visit.

    Yes the infrastructure needs investment but proper research is needed and one week out of  an ICE mindset doesn't count.

    Not everywhere has Tesla Superchargers. I think there is only one Tesla Supercharger in Lincolnshire, that’s in Grantham so about 90 minutes drive from, say, Grimsby.

    I don’t know which EV you have but if you aren’t going below 30-40% you could probably manage with a car with less range.

    Tesco don’t give away petrol but frequently gave 5p a litre off vouchers which for my motorhome is worth about £3.50 compared to around 35p of electricity if you spend an hour shopping there. I usually top up at Tesco if there is a space and it just about covers the round trip. 

    I have a 2021 Leaf and like, I suspect, most drivers I don't drive the full range of the car all the time. 

    I do not behave as I did with an ICE by driving 90% of the range then filling up to the top. I now drive as necessary and fill to 80% unless planning a long journey.  Four hours Octopus Go at 5p/kwh gives me around 40% refill so refilling from 40% suits me and any opportunities for free charging can also be taken e.g. Tesco.  TBH the novelty of a free charge loses its charm compared to 5p while asleep 😀

    Since April I've probably used near the full range 4 or 5 times and been grateful for it.  Would you suggest someone with a 800 mile diesel replace the fuel tank with a milk bottle?  😉

    Thank you for clarifying. Your usage pattern is not that dissimilar to mine but I frequently find myself returning home with less than 20%. I routinely charge to just 80% but 100% ahead of a long run. 

    When I had a diesel, I would usually run it down until the light came on and then brim it, like I suspect many others do, making effective use of the full tank capacity with a stress free range 4x my EV.

    Had there been a significant cost saving, I could probably have managed with a tank half the size but tank capacity is not a major factor in the price of an ICE whereas battery size significantly affects price of an EV.
