a friend has been advised to stop driving for a period ( probably one month) after a TIA. He lives on his own and has BMW i3. Is there any specific short time storage issues or maintenance that he needs to address?

Such a short time not much issue

However always good advise to leave about 80% charged, and possibly disconnect the 12 volt to avoid it draining if car talks to anything


This blog says store on lifts

I do not know, probably not as they get the fuel from the garage across the road

I was just making a general comment about the fairness of the system.

The system is set up to be unfair tho isn't It? To encourage people to switch

Otherwise you wouldn't see the tax breaks for company car.. the until next year no car tax.. the no congestion charge until 2025 Dec etc etc

What would that cost the club?
100 cars, 50L tank, £1.40 per L
About £7,000 for one day.

2.5 Kw/h, 4 hours, 30p per hour
£3 per car

Not really a fair comparison
It was just a 'generic' comment

However as already said it would probably be just 2 players a day that would get to use the charger and knowing how some think I bet the same people would ensure they get their early enough for it to be them. So if just once a week it becomes a £150 a year benefit if it is made free.

I was meaning the club's system.

Doesn't matter tho does it? There are work places that offer free charging for staff which is unfair compared to those who pay to use ICE

Either way it's unfair , club, supermarket or work place (no doesn't need benefit in kind before anyone jumps on that. We been through that previously)

The clubs chargers have been there since the club opened in 2017, they are type one really basic poor chargers but are free (for those who will pay £60 got a type 1 to type 2 adapter) the speed is 3kw not 7 and there are 6 chargers . The most I've seen charging at once is 3 and that's only recently, normally their dead.

I've spoken to the GM about it he said he doesn't have the date yet but they are getting them upgraded to type 2 chargers however they will become pay to use. Which is the right thing to do. They cant make the current ones pay to use as they are proper basic chargers. Not smart chargers, they would need to replace them to make them pay to use .. so at the mo like you say the system is unfair. Can't say it's worth writing to the club about tho .. so really a non issue

Charging experiment #4: going for full

As I was not going to use the car over the weekend, I decided to charge it to full using the home 3 pin connector. I had asked the sparky to put a new 3 pin in the garage, so perfect time to check it out.

start: Sat 2pm.. status 21% / 43 miles

End: Sunday 6pm .. status 100%/207m

Total: 28 hrs /164 miles / 63kwH about £19 (on expensive rates)

Temperature was in single digit all along

At about 11am on Sunday it hit 80% (20-80% in 21 hrs so nearly 3Kw/h) and then (80-100 in 7 hrs, so nearly consistent 3Kw/h)

On a slightly annoying note.. the claimed range of the 7kwH battery is 220miles. So good to see it show 207 on the display.

That will certainly help you be ahead of the game this week. Least you can grace charge each night and see how you end up by Friday

That is my plan… Mrs planning to use the car on 3-4 days at least next week… so let’s see. Walk charger coming on Friday which will change things… once it is in place, I will be straight onto Octopus to switch to a lower tariff


BTW is 7kwH considered as a ‘fast charger’?? Manufacturer recommends charging upto 80 with fast charger but no such recommendation for granny charger .. hence I let it go all the way to 100..: ( not so sure about a 7k one)

No faster charging is using DC, anything using AC (which is what you use at home) Is just normal

80% with DC is perfect , anything above 80 the speed ramps down due to the chemical process of charging

On the bright side, that’s 19 quid for a 4/5 of a tank. I’m £35 for a quarter tank in the 8 series.

If I had 0% in the Kia and charged all night because I just had to be somewhere it would cost me (36 KW at 28p and 28kw at 9p) £12.60

The Alhambra is a massive 73 litre a whooping £105. Sure I could go 600 miles on average for that £105 but 3 "tanks" in the Kia would be more than enough .. and less than half that cost.

Think what's more depressing ATM if I needed a full tank at pay at pump I couldn't even do it because £99 is the limit. Ridiculous costs of fuel

When petrol was at 159.9 I had to do two transactions to fill the 8er.

M340i only has a 60 litre tank but goes through it at double the rate.

Corr I can imagine. I try and fill the big car up every 2 months. Doesn't really get below half a tank just out of habit incase it's needed.

Going to be interesting to see how many miles it's actually going to do this year once we can all fit in the Kia. I mean it's got one holiday penciled in when the wife takes the kids away but that's about it 😂

Best keep that 12 volt charged up.

This morning woke upto temperatures of -2 and frozen water droplet over the car. Ran the pre-conditioning. Last night i had it left it at 100%/207miles. This morning the car was 99%/197 miles. It is not liking the cold weather.
Mrs drove about 25-28 miles to work this AM. I can see the app saying.. 80%/155miles ..

The whole range reliability due to poor weather is another big factor against EVs

As part of the building works we are currently doing, I took the bullet to rewire the garage. Initially it had a bulb and everything on extension boards. So asked the sparky to put some lighting and couple of sockets.

Similar to you, a few posts ago @pauljames87 also suggested a socket for jet washing the car/mowing. So asked the sparky to add an additional socket near the door on the inside.. so now charging the car via that.. the cable nicely goes under the garage door




Curious about this. How did you split your single phase from the leccy board to 3 phase? Normal sparky or the Board? Do you need permission. If I go down the route, I need to do it this week before the 7k charger goes on the wall. Will it work with solar feed back ?
Just to add a bit of clarity on the upgrade to 3 phase.

Typically in town the main cable running down your street will be 3 phase, this will be a 4 core cable carrying 3 phases and a neutral. Each house in your street will be connected to one of the phases and the neutral by a 2 core cable.

UKPN will base their costs on what is involved to replace your 2 core cable with a 4 core. Length of run and if a road closure is required all adding to the price. They might also try to saddle you with some extra costs if they decide the local Sub-Station is fully loaded already and they need to upgrade switchgear in there. Unlikely but it does happen.

(It’s cheaper for Peeps that live in the countryside where they are supplied by overhead lines)

Once you have your 3 phase you need to get your supplier to swap your single phase meter for a 3 phase one. This should be free.

Then you need to get a sparky to fit a 3 phase distribution board in your house, this only needs to be small as it only needs to supply one piece of 3 phase equipment (the EV charger) and a single phase supply to your existing consumer unit.

So it’s not a small or a cheap job upgrading to 3P+N

As per PJ fast chargers are DC straight to the battery using the big pins/sockets on the car and tethered cable from the charger.
'Slower' charging is recommended as the way to extend battery life.

The guess o meter is to 100% be ignored is the issue. It is running calculations so often it's very hard to keep up

For example when you put the heater on at that initial bit where it's using the most energy it will drop the range because it's predicting you will use that rate of energy constantly.. but you don't and then the range goes back up

Certainly doesn't like the weather but what to look at the miles per kWh you get summer and winter and times by the available kw in the battery to get the true range

Another example is I've woken up with 40% battery in the winter before and it's said 45 miles. My work trip is 50. I know it can easily do there and back with range to spare. Sure enough got home with 10%.

Once you get used to the car itself your range anxiety will go

Altho studying the app doesn't help 🤣

Oh one add. The range using a 3 pin plug I find for some reason it just thinks it's going to be more. I'll do a 3 pin to 100% it will say 215 miles.. if I do with a 7kw it says 180 miles which is more realistic

Soon adjusts when you move
