    It's correct but in many cases you'll only get that curve if you plug in below 15% SoC

    If you plug in at say 40%, then you won't get 125kW from the graph, you'll get around 75kW

    That's been my experience at least, pretty sure I was being limited by the car

    For example I recently got 18kWh in 15 mins from a Supercharger. Quick maths gives an average of 72kW. As I recall I plugged in somewhere around 30-40% after about an hour of driving on a warm day

    I've gotten 125kW exactly once (back when that was the limit) from an Ionity charge after driving for 3 hours and plugging in around 10%

    That seems wrong. Not doubting you, but just seems wrong that the car won't join the charging curve at the SoC. I know those charge curves are derived from a ~0% SoC up, but any time I've plugged in my car, I've always hit the curve exactly as the graph would suggest based on my current SoC.

    Seems to be a VW thing, other ID owners can probably chime in with their experience

    I guess whoever designed it always waits until their fuel light is on before filling up 🤷‍♂️

    They seem to have dramatically improved it with the newer generation of cars because they now have a button to precondition the battery. The cars will also precondition when navigating to a charger (the thing they were supposed to do in 2020) and will display the max available charging power, taking the guesswork out

    Sounds like a poorly thought software. Toyota updated theres to improve the curve.

    VW seem to be reluctant to support the software in the cars for long enough. Your phone will get updates longer maybe.



  • Registered Users, Registered Users 2 Posts: 13,005 ✭✭✭✭the_amazing_raisin


    Apparently the current version of software shipping on cars (4.x) is already EOL and Cariad are working on version 5

    And then Cariad will probably be shuttered in favour of the joint venture with Rivian

    It's Windows ME all over again 🤣

    Saw an e3008 today WTF are they deliberately makings EVs ugly

    I genuinely thought it was a Chinese knock off the 3008,



  • Registered Users, Registered Users 2 Posts: 7,319 ✭✭✭zg3409


    Fastnet charge curves are best case ideal curves. If your battery is hotter or cooler than ideal , typically 30 Celsius, then rate will be slower. As battery ages the speed may drop too.

    chancing me arm here.I am in Waterford city until Wednesday visiting for a few days . Could anyone lend me a granny/3 pin charger with a type 2 connection?

    (Like a gobshite, I bloody forgot mine at home, was cleaning car last week and forgot to put the granny charger back in) 🙄🙄

    Fiat are to have integrated charging cables, starting with the Grande Panda next year. Obviously only for AC due to cooling issues, and even at that, only up to 7.4kW. There will be another normal charging port for DC up to 100kW. I hope it also allows faster AC or the whole thing seems a bit of a waste.

    I'm struggling to figure out whether that's a good or bad idea. My instinct is bad idea, seems like it causes more problems than it fixes

    Honestly an easily accessible storage box for the cables would be plenty. Somewhere they won't be blocked in by a boot full of shopping, like perhaps under the bonnet 😉

    You might be right. I assume it's just easier. I've seen it demo'ed and it looked convenient. Pros and cons as you say.

    @Gumbo appreciate your thoughts on fitting regular tyres to a Model Y or do they have to be the EV specific tyre ?



  • Moderators, Society & Culture Moderators Posts: 42,249 Mod ✭✭✭✭Gumbo


    I had non EV tyres fitted to a Nissan Leaf (Michelins) and non EV tyres fitted to a Model 3 (Pirelli). On the Leaf, noticed no difference but that was a L24 back a good few years ago. On the M3 I noticed it a bit louder than other M3’s I was in at the time but there’s so many circumstances that could have caused that (Fremont built V MIC) etc

    Id Have no hesitation fitting non EV tyres to an EV once the load rating and Speed rating are matched to OEM figures, 92Y for example.

    In theory you may suffer less range or louder drive but That’s in factory testing conditions. On the road with Irish surfaces, radio on, kids battling in a royal rumble in the back seats, would you notice?



  • Registered Users, Registered Users 2 Posts: 13,005 ✭✭✭✭the_amazing_raisin


    I'm going to second this, got non EV tyres fitted to the Leaf years ago. There was maybe a 5% increase in consumption for a month or two and then I think the tyres wore in and lost a little bit of rolling resistance

    There was a corresponding slight increase in road noise which again disappeared after a few weeks (or else I just stopped noticing)

    From what I can tell there's a trade off between grip and efficiency with tyres. Increase one and you start losing the other

    Personally I'd favour more grip since (as someone put it very succinctly earlier) the tyres are literally the only point of contact with the road. Generally when you need good road grip, you REALLY need it and I'm willing to sacrifice some range in exchange

    Good news for anyone travelling on the M1 and looking for somewhere for the kids to burn off some energy, Applegreen have significantly improved the play area in the Lusk service stations

    Looks like the bathrooms got redone as well so they're less of a horror show

    Bad news is there's still a single charger at each service station, so you could end up with plenty of time to spare if there's a queue 🙄

    Is it too much to ask to get good facilities and good chargers in the same place?

  • Registered Users, Registered Users 2 Posts: 14,203 ✭✭✭✭Flinty997


    The M1 is one of my few regular long distance journeys. Apple Green used to be my go to stop. But no longer due to the lack of charging. My last time there someone was charging to 100% heading to Limerick or such. I'll not be stopping there in future.



  • Registered Users, Registered Users 2 Posts: 13,005 ✭✭✭✭the_amazing_raisin


    Yeah it's very frustrating, there's Ionity in City north but that has nothing going for the service station

    There's also Clonsaugh coming soon hopefully, but again not a place you'd want to spend any amount of time there

    The Applegreen sites at least have some decent facilities (because TII probably forced them to) but a single charger per site

    Unless you've a Tesla of course

    If Applegreen would speed up their rollout, and increase the scope it would improve things a lot. At this stage 2 chargers per site isn't going to be enough when 5-6 is becoming the norm

    And Applegreen don't even have 2 chargers per site 😬

    City north is too close for me leaving Dublin heading north ish. Still there are some decent options further north just off the M1 on my route. Now I know to avoid AG I can plan around that..



  • Registered Users, Registered Users 2 Posts: 14,203 ✭✭✭✭Flinty997


    When I got my EV there were a mixed set of no name tyres but decent reviews. One deformed (lowest load rating one) So I replaced them all with higher load rating sporty tyres. Definitely noticed a slightly stiffer ride and a slight increase in noise. The other half didn't notice. Ramps probably the only place I notice it.

    The EV Charging arm of Applegreen has only been going a wet week. With 200+ stations in the country is it any wonder it's taking them so long to rollout chargers. I guess they identify the most lucrative sites and start there by dropping in a charger before moving on to the next.

    For M1 travellers I can see on plugshare they are planning to install a charger at their M1 Balbriggan service station and slightly further off the motorway will be another charger at their service station at Balbriggan Shopping Centre. It should improve the situation.



  • Registered Users, Registered Users 2 Posts: 14,203 ✭✭✭✭Flinty997


    "a"..."charger"...?



  • Registered Users, Registered Users 2 Posts: 780 ✭✭✭Exiled Rebel


    Isn't it obvious it doesn't make financial sense to install more than 1 in a lot of these locations? Or at least it doesn't until EV's are a greater % of the fleet.

    Entities like Applegreen, Circle K and eCars for example are not providing a public service. Where they install needs to make business sense.



  • Registered Users, Registered Users 2 Posts: 7,319 ✭✭✭zg3409


    Seasoned EV drivers will drive past single site chargers towards hubs where they are less likely to encounter a queue, a broken charger without another one next to it, and possibly a better food offering. In the future old small petrol stations that serve local gas guzzling owners will struggle to survive. Most EV drivers will charge at home or work, public charging will be expensive and avoided. Public charging will mostly be performed on longer inter city trips at hubs. Apartments will eventually get chargers and possibly supermarkets will join the game with 50+kW chargers. It's unlikely a local petrol station with no real grid connection and room for 10-30 cars will be viable even if they had chargers, the grid upgrade and usage would be low. The whole business model of drivers visiting once a week and buying groceries and overpriced coffee and moving on after 5 minutes may be a world away. My (very young) kids thought the red petrol station was a fire station, as they had never been there and did not know what a petrol station was ! ⛽ I want a hub 300km from where I live or 150km+ so I can top up when I need it. Everywhere within 150-200km of my home is home charger range.



  • Registered Users, Registered Users 2 Posts: 780 ✭✭✭Exiled Rebel


    While I agree with what you say will happen in the long term the reality today is that we're still in the early stages of adoption. The transition as we're currently seeing involves the rollout of one or two chargers dotted around the place. They will either be pulled out in time or additional chargers dropped in to create hubs as EV's become ubiquitous.

    Until then the business case of installing multiple chargers doesn't stack up for a lot of locations.



  • Registered Users, Registered Users 2 Posts: 6,273 ✭✭✭kirving


    In some ways, just installing a single charger is a very bad idea.

    Even if it's utilisation is high, very quickly you get a reputation as full, and similar reputation issues if it's down for any reason. First impressions are everything, and it's hard to recover from that.

    (There's a petrol station that I avoid, purely because they served me horrible sausage rolls once. Irrational but I'm not taking that chance when I'm hungry and on the way to work.)

    The problem is though, it's very hard to justify that extra investment up front for more chargers. There's also the issue that the install price doesn't necessarily drop the more you install.

    The first X number is probably cheap enough, but once you hit your electricity supply limit, it's a big step up to install N+1 chargers.

    Sorry your out of touch....

    This is the M1 one of the countries main motorways. And north Dublin coast, beaches are real black spots for chargers. It's crazy there are not more charging hubs on this route.



  • Registered Users, Registered Users 2 Posts: 780 ✭✭✭Exiled Rebel


    As I said it's a transition. In a couple of years the M1 will be served with adequate charging infrastructure and this discussion will be long forgotten.



  • Registered Users, Registered Users 2 Posts: 14,203 ✭✭✭✭Flinty997


    It's not a transition. The M1 route is lagging behind, due to Applegreens shenanigans.

    It's quite something to advise people the best place to charge on a route is not at the motorway services.

    What shenanigans would these be? You seem to have some inside knowledge.
