In my RAF days, I heard of quite a few occasions where a power set was towed away from an aircraft whilst the cable was still attached to the aircraft, causing damage to the connector. Is there a safety link in cars that stops you driving off whilst still plugged into the charger?

Yes if plugged in mine won't move

I even just had the adapter in (no cable attached to it as I was moving over one charger) and it wouldn't move

We drove to the Alps a couple of weeks back and drove back last Saturday. Every fuel stop on the motorway was queuing for petrol and diesel both on the way, and on the return journey, but they can obviously cycle the refueling process pretty quickly. Quite a few people also making the journey in fully electric vehicles and although the recharge points weren't queuing - they were pretty full.

However, if every vehicle had been fully electric, it would have been total carnage - the technology will never work when you have predominantly electric cars, making long journeys, where multiple recharge cycles are needed.

@Hobbit a few weeks back you asked if I was worried about 2 EVs and charging both.

The new charger goes in Thursday , replacing the old one. That's just to save and extra 1.5p a kw, which the £175 saving over a year (including the extra solar export fee) will cover the charging for the second EV

Almost 2 weeks with both cars. On nights I've brought in the wife's car to give it a good run. When I got to work (25 miles) it had 62 % left. I left work in it on the 13th. Drove home. Been doing local journeys in it and then back to work today . This is the first time I've ever charged it lol 😂 they delivered it with 100%. By morning it will be at around 90%

My car having a night off today but that's at home on 84%, that's only been charged once at home thus far but done 915 miles since I got it in January

Clearly over time Motorway Services will need to increase the number of chargers. Space will not be a problem as they take up no more space than a normal parking space. Grid capacity likely to be the biggest issue which national grid are working on. With the right investment I can't see why is shouldn't be possible. After all we transitioned from the horse and cart to motorised transport with few issues.

I watched it. That channel is starting to irritate me. It's about as impartial as the numerous EV-bashing ones, but in the opposite direction.

Gridserve is all very well, but its trading model seems to be that it wants to build shopping malls where you happen to charge your car while spending money on other stuff that you don't need.

It was noticeable that they never mentioned the price of the electricity. They forgot to edit out a fleeting image of a charger displaying 79p/kWh, which if you're very generous and assume 4 miles/kWh makes the cost 20p a mile. Which is significantly more than petrol.

Another confirmation that an EV only makes sense if you can charge it at home.

Surely building something to do is a good idea rather than just letting people sit board in Their cars no?

Yes public charging is expensive, home charging is king. All about averages tho. He will have charged at home at his 9p per kWh. Then at say the 80p per kWh .. all about the average cost.

Before the energy crisis gridserve was 30p and home charging was 14p day 5p night

Energy costs are dropping , charging will come down quicker than petrol has.

I’m still not seeing how the charging works when there’s high demand. The service areas we stopped at through France were all full, cars parked on verges, queues into the petrol stations etc. If every car is electric and needs to stop for 40 minutes to recharge, at a reduced range in comparison to a diesel or petrol vehicle - then there simply isn’t enough capacity on the current service areas to accommodate them - and the costs and practicality of making every single parking bay a charging point would never work.

Most electric cars sold today will do around 300 miles on a single charge, by the time a majority of vehicles on the road are EV's that will almost certainly be over 400 miles and maybe similar to ICE vehicles. At the same time charging times are coming down and will be down to 10 mins or less for most EV's come 2035. Clearly more charging bays will be needed but no chance that all bays would need to be taken up, a third at most.

Last evening Mrs told me she is planning a surprise trip with MIL to B’ham.. 270m round trip. Glad she told me last night.. because I could change the settings and fill the car to 100% rather than the usual 80%. Even now she will have to top up on her way back. Will add another 30-45 mins to her journey for a charge

Else she would have been more surprised to see that the elephant on the driveway is not one for surprise trips.

On a more positive note.. last night I finally got Octopus Intel Go to fully control the car charging situation. Plugged it in around 8pm when Mrs got home. Octopus created a charge map.

It was to charge to 80% so would have kicked in around midnight.

I changed it to 100% from the app and it remapped it to start at 10:30. This morning it is 100% charged.

It took a few changes in settings with the charger tech support. They must have realised how dumb I am and made all the changes to the charger and my app settings remotely!! Octopus then took over and charged the car overriding the car setting. I felt like a postmaster in the horizon system. But this worked. I can see a few cyber loop holes into this ever connected ecosystem.

How is that likely to affect battery life, if at all? I assume that rapid charging is worse for the battery than slower charging so will it shorten the lifespan of the battery?

Not all... All comes down to battery size and that is directly proportional to car cost. To keep cost down, companies are fitting smaller batteries rather than compromise on interiors. The basic premise is that 90% of the people/trips are shorter than a 300 mile journey and folks can reacharge easily.

i have a 2023 BMW iX 40... it can barely do 200miles. It has a 70KW battery, and in theory it can do 220-250 miles on a charge. HOWEVER, the recommended charge is 80%, so that kind of restricts it under 200miles. In real life it does less. But it is the most luxurious car that i have ever had. Unbelievablely brilliant. Shame they dont have a bigger battery option. The ix 50 and 60 come with a 100kw battery but are cost nearly 30-50K more than the base model. But i am guessing we dont do do 200 miles every day.

As expected got a panic call from the Mrs who is using public charging for the first time.
1) The first gun she used, would not charge.. total chaos of which card to use and how to do it, cables locking up and not working.
2) frantic video call to me to tell me how this is all my fault and walk her thru the charging process.. never mind the fact that i told her to preconditon the battery which she completley forgot
3) From the video i could see 4 parking bays and she had chosen the first one which was tight up against a hedge and was always squeezing past it as she went in and out of the car. So i asked her to repark the car in bay 2
4) She called back saying she had parked in bay 2 but it still did not work. On video I saw her parked in bay 2 but for some mad reason chose to pull the gun from bay 1 and charge even though bay 2 gun was free.... Women!! when will i understand you
5) bit more fighting and blaming me later, told her to use Bay 2 gun.. and bingo it worked!!!
,... I went from pariah to priest in 30 sec.

Its only taken her about 25 years of driving to not blame me for anything going wrong in a petrol station. Now i am back to square 1..

I'm just trying to point out that in having an EV there really are a lot of problems one has to overcome that are not always made clear.
Mudball is certainly finding things out that I had no idea about.
It's just not as simple as plugging the car in and getting a battery charged up.
I'm actually finding this thread very educational.
