EV general discussion

[Kenai]

No idea how this is going to work if your car is not linked to Octopus. My Ohme app charges all over the place in chunks. It’s meant to be linked to Octopus so maybe it will adjust itself. Going to add a fair whack to my charge cost if it’s only 6 hours a day at 7p I need 60kw a day.

They do seem to have overlooked charger integrations somewhat so far, especially regarding the varying charging rates that can occur, I would expect a bit more information to appear regarding how those sort of integrations work.

Imagine the ****storm if they bin off Ohme integration because it's too hard to make it work with the tariff like OVO did

Just spoke to Octopus and it’s only 6 hours a day at 7p. Will be looking elsewhere tbh.

I sent a grumbly reply to Octopus about the changes, and got a response from them:


I think the last sentence is pretty significant - this will alleviate any concerns I have.

indeed... as much as it is gonna be more of a headache for us to manage being a 2 EV family, and without a doubt at times its gonna cost significantly more than it does now.......

It has been clear for some time that it probably was not going to be sustainable permanently. So many people were deliberately gaming it, it was possible to get almost 24/7 7p electricity for some people..... and whilst it grates that a few people taking the ..... means we cant have nice things it was entirely predictable.

Personally i was hoping for a more nuanced change which tried to weed out those they thought were routinely pushing it too much whilst still allowing people to take the odd liberty when they do need the extra, but i can see that for octopus this is probably a better way.

it was good whilst it lasted and is still a competitive product..... a few of my friends are already in the process of leaving. I am not sure its worth it, my view is if octopus are dialing back then EON may do too soon enough (also as already mentioned by other folk in this thread, if you have solar octopus export is better unless you have a solar install or battery install supplied by EON) however I shall keep an eye on the situation, if nothing else i can get a £50 referal if i need to

Yeah you need to calculate how much of your charging will be at full rate vs 7p and whether alternative suppliers make more sense.

The whole irrational 'rage quit' thing where people leave even if IOG could still be competitive for their usage blows my mind though

AFAIK your only other option is EON if you need more than the fixed overnight off peak period to charge and they don't look to support Hyundai on their intelligent tariff.

Especially when you consider that if Octopus are reaching the point they're having to be a bit more strict about their T&Cs, it's unlikely there's going to be another supplier out there that'll offer anything significantly better, at least not for very long.

been there once - and then finally all the screens and computer shuts down all bar legal features (never seen that and if i did i think i would be worried!)

doesn't tesla have an easter eg 'time to die' or 'Daisy Daisy'

several a390 road reviews at least in france seems a lease price competitor for the bmw ix3, ioniq5n with better dynamics inc 2rear motors - can't see uk lease pricing on web

Just thinking about it, now that Octopus seem to be splitting out car/house usage more so than previously. Would it not be easier all round (and also solve any issue with charger throttling) to just give us 1176kwh of car charging usage every 28 days at 7p. Then chargeable at peak rate above that, effectively moving us all to a drive pack style setup.

I don't think that would meet their objective, which is to restrict car charging to really low demand periods.

Yeah had a quick look and nothing is any cheaper or compatible. See if Tesla energy comes out anytime soon.

The problem with that is that they still want to be able to control when that is occurring to make things most effective for them and that wouldn't encourage the 'plug in a lot so we can charge at the best times'.

The 6 hours thing strikes a bit of a balance - there's still the incentive that you MIGHT get an extra few hours of cheap household electricity if that works for them, encouraging you to be plugged in but doesn't also encourage the use / users that will sit constantly drawing power from 5pm to 8am which doesn't help them.

edit - and we know the Drive Pack approach is probably not working out in their favour given they've closed it to new sign ups and have been telling potential customers that it has been 'retired'.

I had my Model 3 down to -5%

I stopped to charge at Abington services with 5-6% left. When I tried to charge, the onboard DC charger was broken.

I decided to drive extremely carefully to try to get Tesla Edinburgh, I figured I might as well try to get there, and if I break down on the way, then at least I'm closer than I was previously.

I turned the AC off, driving as carefully as possible to preserve charge. I arrived with -5%. The guys at Tesla Edinburgh had the AC charger fixed and I was back charging again (for free!) within 45 minutes, incredible service!

TIL Tesla displays a negative state of charge (which is totally nonsensical but never mind...)

Why would the onboard AC charger be relevant for fast charging?

maybe he snuck his 3pin granny plug into a socket at burger king whilst grabbing a whopper

 

[Scon]

Sorry, I meant DC!

 

[b0rn2sk8]

I recall Tesla had an issue where the harness which runs between the charge port and the high voltage battery can work lose which prevents DC charging but didn’t impact AC.

It was probably that and why they were able to get you back on the road so quickly.

My brain totally read this as him grabbing a whopper of a granny at Burger King.





I might need help.

Once I described the issue, they knew immediately what it was, so that would make sense.

Late 2021 Model 3 btw

You have quoted someone asking them about a Tesla when they dont have one. Why?

about 4% but I wasn't worried as my mates house was close by.
the most nervy I have been was on the motorway it was pounding it down with rain with a very heavy headwind. I had planned a service station stop at the large place off M6 at rugby but realised I wasn't going to make it. I had my kid and wife in the car who is nervous at the best of times.

it was still ok once I made the decision to give up on my initial plan I just had to come off motorway sooner and charged elsewhere.

I have run out of petrol before but (touch wood) never run out of charge

6 miles left showed 10 miles remaining but i did have a section of the M40 which was much faster than the previous countrylane section. So basically the range started to plummet and squeaky bum time. I knew it was a risk so atleast let the car roll to a stop out of the way

Fundamentally its not like fuel where you will run out of the fluid, once a cell module or indeed the whole pack hits a voltage measurement then it will shut down, battery temp, previous demand and load all make that point an estimation.
