    Meanwhile Toyota are threatening to stop producing cars in the U.K. if the U.K. government bans hybrid cars from 2030 onwards…..


    what a company…..

    No doubt the next Tory overlord will bend over backwards to do whatever Toyota want 🙄

    I picked up my first ever full EV last week (MGZS EV Exclusive long range), left behind the phev that served me well for 4 years. Tipped around at home on short runs and this is my first longish trip away.

    Just a trip from Galway to kilkee for a few days, add a few small trips back and forth to the beach etc. And home again tomorrow. I Will be home with about 34%. So not the full "living with an EV" experience that needed charging stops.

    That is later in the week when I head to cork, I reckon I'd make it home, but a quick top up just to be sure I get home will take the edge off.


    But I did get my first taste of the charger situation. Two 22kw chargers at the beach. Arrived to see an outlander plugged in and an MG5. Outlander was plugged in at 1:30 and stayed until almost 7pm.

    It was a 2014 one so only a 10kw battery. So they just used it as a parking space for the day.

    Luckily I didn't need to charge, but I was still annoyed for anyone that did. had I been stuck, three kids in the back and the next charger a good 30mins away, it would have been very frustrating.


    But so far first week was great. 260 km around at home before it went under 50% (I did a tiny top up on the first day at home to make sure the charger worked, and another 3kw at an ESB station to make sure that worked). This weekend about 300km driving and still plenty in the tanks.

    It's actually surprising how much of Ireland you can cover on round trips without charging.

    But what I did notice is my change in opinion of the amount of charge at either end.

    I got here using 25%. So I know to get home it will need 25%. But still when the route planner said you will arrive home with 34% to spare, my first reaction was phew that's cutting it close 🤣

    The 22kw chargers are destination chargers so in theory they done nothing wrong. There should be more of them there!

    The Outlander charging at 3.6kW would have been full after maybe 3 hours. Decent thing to do would be move it, especially if close by but many don’t :(



  • Registered Users, Registered Users 2 Posts: 66,636 ✭✭✭✭unkel



    Reap what you sow. In most counties (not in Dublin) parking is free when you are charging and the EV charging spots usually are in the best locations. And there is no penalty for charging for a long time on destination chargers. It's a big ask to expect the Outlander owner to interrupt his day, come back to his car, move it to another spot (if they can even find one) and then having to pay for parking.

    It’s pretty poor design. If the premise is that that they are long-stay parking spaces, eCars should never have installed 22kW chargers there, they should have gone for a larger network of 3.5kW chargers instead.

    If they were trying to install what the Dublin LAs are now calling neighbourhood chargers, 7 or 22kW chargers would have been more appropriate.



  • Registered Users, Registered Users 2 Posts: 13,003 ✭✭✭✭the_amazing_raisin


    Ah now, you're making far too much sense with that kind of talk 😉

    I'll leave the article below to truly get your blood boiling

    Despite the title, and just to be clear, that's 10,000 charging points for Stockholm, from one company, on top of the 5,000 they already provide...

  • Registered Users, Registered Users 2 Posts: 66,636 ✭✭✭✭unkel


    There would be 3ph supply so a 22kW charge point would cost no more than a 3kW charge point to install. The initial network of AC charge points in Ireland was very good and very early (thanks to the Green party) but there has been almost no improvement since. Of course we now need a lot more of them. Many towns have none. They all should have had at least 100 each by now. A city like Dublin should have thousands of them by now, not a few dozen.



  • Registered Users, Registered Users 2 Posts: 8,228 ✭✭✭Grumpypants


    It is in a pay and display car park right beside the beach, so you do still have to pay, and they were likely only a 30 second walk away. And while it was busy, there was a constant movement. I drove in at 4 and got a spot right away.


    I drove an outlander for 4 years and rarely used a charger, let alone blocking one while not charging. A 0-100% charge on the 22kw would only take 3.5 hours. So at minimum they were not charging for 2 hours while parked.


    My own approach is take what you need and move on. A outlander never needs a charge.


    I plugged in at that charger before in winter, other one was free and I still left a note in the window for anyone that was stuck to ring me and I'd move it.



  • Registered Users, Registered Users 2 Posts: 66,636 ✭✭✭✭unkel


    So you plugged in your PHEV into a public charge point, while stating that a PHEV never needs a charge?

  • Registered Users, Registered Users 2 Posts: 3,548 ✭✭✭JohnC.


    It doesn't need a charge in the way that no PHEV needs a charge and can be driven in ICE mode. But it is better if they are charged and driven in EV mode, no?



  • Registered Users, Registered Users 2 Posts: 8,228 ✭✭✭Grumpypants


    Yeah phevs never needs to charge, it can make it home on petrol. An EV doesn't have that option. If it's out of juice there isn't a back up engine. That doesn't mean it can't ever charge.

    It's silly/inconsiderate to charge a phev when others need it. And it's downright dickish to block the charger when you aren't charging as this guy did.

    When I plugged in, it's a seaside town in the dead on winter without another car in the whole car park, never mind charging, and both chargers free I'd say that's okay to plug in for an hour.

    Yes you might get two EVs in dire need of a charge arriving at the same time. That's why I left a note with my number on the dash to say give me a buzz if you are stuck and I'd move it.



  • Registered Users, Registered Users 2 Posts: 13,003 ✭✭✭✭the_amazing_raisin


    Well often with a PHEV you'd want to maximise EV range, so you're forced to graze at every available charger to do so. It's one of the things that I don't like about them as you actually end up charging more often than an EV

    The owner really should have moved their car after it was charged though, that's somewhat inconsiderate not to do so

    The thing is, this problem is entirely solvable by just adding more chargers. 2 AC units for a busy seaside town is an absolute joke. There should be more like 20 chargers

  • Registered Users, Registered Users 2 Posts: 16,178 ✭✭✭✭AndyBoBandy


    And on top of that ^^^^ there should be some PHEV ‘friendly’ chargers that are only 3.4 or 7kW…… means you get more plugs for the same power that an AC22 would have….



  • Registered Users, Registered Users 2 Posts: 13,003 ✭✭✭✭the_amazing_raisin


    I kind of feel that's too complicated. 7kW AC should be enough for most destination chargers. 22kW is nice but the majority of cars don't make good use of it, and unfortunately there isn't much sign of that changing soon


    There should just be lots of chargers, banks of a dozen at a time. For cars that need more, there should be a 50kW hub nearby

    The whole free parking thing needs to go, too open to abuse. IMO, for the AC chargers the parking should be paid but the kilowatts should be free, no advantage then to blocking the chargers, and if one is blocked then there's lots more beside it

  • Registered Users, Registered Users 2 Posts: 16,178 ✭✭✭✭AndyBoBandy


    Still madness that eCars said they are not installing any new AC chargers…….. they’re barely installing DC chargers as it is!

    there’s huge need for destination charging, and everywhere (we’ll, everywhere that folk would expect to spend 90+ minutes….)



  • Registered Users, Registered Users 2 Posts: 8,228 ✭✭✭Grumpypants


    Big difference this morning, was over to the pool and there was 2 EVs plugged in on the way in. Then 2 more on the way out. So 4 cars charged in half the time one phev was there.


    Got home anyway tonight, over 120km left on the range. 5 hours of driving, 300km done including some motorway and AC on to clear the foggy windows.


    Off again midweek to cork. This will be 407km on so this one might need a top up just to be sure. Car does 450+ but that's cutting it fine.



  • Registered Users, Registered Users 2 Posts: 13,003 ✭✭✭✭the_amazing_raisin


    I guess the argument that a few DC's give you more bang for your buck has some merit. The income is probably better, ESB knows that they're only going to get used more and more and the price per kWh is higher


    Still, for the cost of a single DC you could put 7kW AC posts along a whole street

    I suspect getting an LA to actually agree to that would be some hurdle, they have some bizarre attachment to the idea of installing a single AC charger in some random car park

    They did look into the commercials of AC charging as part of the Dublin Local Authority project, the return on investment just isn't there unless the capital funding is heavily subsidised, if an operator is 100% paying for the capital costs they estimated that the chargers wouldn't be profitable in the first 10 years.

    This means for destination charging either the destination itself should fund the install (like Tesco did with eCars) or it comes from government funding. Given the blowback eCars got from the EV community for installing AC chargers at supermarkets I can see why they don't want to be in that business.

    Installing one 50kW DC charger that can break even in 9 years is a much better business proposition than installing 7 7kW AC chargers that will still be losing money before they need to be replaced.

    Toyota is having a tough time at the minute with their BEV recall for wheels falling off and a worsening emissions scandal (trucks, not cars but you'd have to wonder about cars too!)


    Looks like emission cheating is/was widespread and not just a VW thing.

  • Registered Users, Registered Users 2 Posts: 66,636 ✭✭✭✭unkel


    Going back to 2003 when Toyota started cheating. Wow, that must have been many years before VW. I wonder did they sell any of those cars / trucks in the USA? If so, VW paid a $15 billion fine over there, Toyota could be next up on the block. I'd say at this stage it is more likely than not that Toyota will not survive long term as a major car company unless they are rescued somehow.


    In a generation or two people will laugh at us, silly people who thought they could make dirty combustion engines clean. We certainly did try every trick in the book, invented ludicrous systems like start stopping of the engine all the time, exhaust gas recirculation, tiny engines with turbo chargers, catalytic converters, particulate filters and when none of it really worked, we had no option but to cheat.



  • Registered Users, Registered Users 2 Posts: 23,106 ✭✭✭✭ELM327


    The irony is that Toyota had the best emissions reducing tech of them all (Lean Burn), in the best car they ever built (Carina E), but it got outvoted by catalytic converters.

    Cats were and are a waste of precious metals, they make cars more inefficient resulting in more fuel burning not less,and ultimately the incremental fuel burn from adding cats to cars has wasted months if not years of oil.



  • Registered Users, Registered Users 2 Posts: 2,018 ✭✭✭kanuseeme


    Hino has an annual production of 130000 units, VW 8 million or so, fines per rata probably will be small change for the largest car maker in the world.

    Honestly, I do not think that Toyota is going to lose out that much given the perceived reliability of the brand, their successful self-charging gimmicks, while on the other hand, nearly every EV brand has battery replacements ( 4 OMG I cannot believe that.) or degradation of some sort.



  • Registered Users, Registered Users 2 Posts: 4,112 ✭✭✭wassie


    Their Australian operation is also facing a possible AUD$2 billion class action by owners of HiLux, Prado (our sold in Ireland as LandCruiser) and Fortuna (SUV based on HiLux platfrom) who bought vehicles with potentially faulty diesel particulate filters (DPFs).




  • Registered Users, Registered Users 2 Posts: 13,003 ✭✭✭✭the_amazing_raisin


    I heard some commentators saying that emissions cheating was basically standard practice in the industry. Could be just hearsay but I imagine the mistake VW made was getting caught

    Even for the ones that play by the rules, the test cycles are hopelessly open to abuse

  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,262 Mod ✭✭✭✭liamog


    The main mistake VW made was trying to push diesel into domestic vehicles in the US, they were the only ones trying to do it so when the EPA went gung ho at them they had free reign without any US manufacturers to be hurt. Light duty trucks such as US pickups had much less strict emission standards which is what led to the rise of truck based SUVs.



  • Registered Users, Registered Users 2 Posts: 503 ✭✭✭PaulJoseph22


    4 battery replacements, is that true? That’s one to avoid…….



  • Registered Users, Registered Users 2 Posts: 23,106 ✭✭✭✭ELM327


    That was one very early tesla and is not representative of cars that are 10 years newer.

    To offer some thoughts on the battery degradation:

    4 replacements is bad, but also unusual (one hopes). I know Tesla fans can be quite... dedicated, however I imagine only the most devout followers of Musk would stick with Tesla if like 90% of the cars needed repeated battery replacement


    The rate of replacement is what it key, if it's 1% of new cars or 0.001%. And how this compares to the number of petrol cars that suffer a major fault within their expected lifetime. I don't think there has actually been an in depth study into this

    Degradation is an aspect of any piece of machinery (actually anything above subatomic particles if you want to be really strict about definition) and so the petrol engine in an ICE is subject to the same issues.

    The fact that there is a guarantee for many EV batteries lasting 8 or more years is a positive. Compare that to the warranty on an ICE, which does not to my knowledge make any guarantees around consumption or efficiency. A petrol car could in theory be running at twice it's rated consumption, thus halving your range, and unless there is an obvious mechanical issue in the engine still be considered as "good" from a warranty perspective

    I often see people on the news or in this forum saying that older vehicles should be converted to electric because they're "perfectly good cars" and shouldn't be wasted.

    To be clear, an 15 year old petrol car is not as good as the day it left the factory. Cars have a design life, which seems to be somewhere around 8-10 years without significant mechanical issues, everything after that is borrowed time which will likely involve repair work.

    Like any product, manufacturers test their cars beyond their design specs so that even when the factory is operating at the lower bound of their control limits the cars produced will still last the design lifetime. This is why cars don't just drop dead as soon as they hit 10 years. This combined with the fact that a car is expensive and easy to repair means that it's generally more valuable to keep it running than just dispose of it

    But let's just dispense with the idea that only EV batteries degrade. I've seen 15 year old petrol cars that realistically have less range than my old Leaf down to the fact that they'd probably break down if driven for more than 60 mins at a time
