    Looks to me like a case of build a better mouse trap.

    What I noticed is that there is much more information available to the charger over CCS, mainly state of charge.

    But as you said, perfect for a fleet of cars, and good use of a 100kW connection.

    For cars coming and going regularly it's much better than AC.

    All day parking not so much



  • Registered Users, Registered Users 2 Posts: 13,409 ✭✭✭✭prawnsambo


    This could be a good solution for apartment blocks and other residential areas with shared parking. With 100kW shared, that's 50kW and a charge time of <1 hour to get to 80% depending on battery size and SoC. So over night, all ten cars would likely be fully charged (to 80%) by morning.

    Unless I'm reading it wrong of course.

    But to charge 10 cars overnight, everyone would need their own charger?



  • Registered Users, Registered Users 2 Posts: 13,409 ✭✭✭✭prawnsambo


    Well that seems to be the setup shown above. Everybody plugs in, but it's first come first served (in twos), so later arrivals are queued to charge after the earlier arrivals have reached 80% SoC.

    That's my reading of it anyway. Could be wrong.

    But when overnight is mentioned, someone ain't going to get out of bed at 4am to make use of a charger.



  • Registered Users, Registered Users 2 Posts: 13,409 ✭✭✭✭prawnsambo


    Again, this is my understanding of it, so don't take it as gospel. There are 10 stations, you plug in to whichever one is free when you arrive and your charge session is queued to when those before you are finished.

    The car should be able to start a charge session when power comes to its station. I know mine will do that, assume others are similar.



  • Moderators, Society & Culture Moderators Posts: 42,197 Mod ✭✭✭✭Gumbo


    You don’t have to. My interpretation is that all cars plug in and walk away. Charging starts in order.



  • Registered Users, Registered Users 2 Posts: 7,317 ✭✭✭zg3409


    There is only one charger here that selects up.to 2 cars at a time to be connected. Each post is basically a long cable going back to the charger. In an apartment 7kW x 10 would achieve similar and be cheaper.A full fill overnight for most cars. AC can also variably share better



  • Registered Users, Registered Users 2 Posts: 13,409 ✭✭✭✭prawnsambo


    Don't see how that would work for 10 cars overnight. You'd have a max of maybe 12-14 hours which is 84-98kWh available charge, so maybe 10-20% each car depending on battery size. Somebody hooks up with 10% SoC and they could hog the thing for most of the night.

    or just install 14x 7kW chargers….

    I'm trying to create an excel formula for a running cost spreadsheet. Is there general consensus for depreciation these days for 3,4,5 years ownership for new cars, and also for used cars from 5-10 years old.

    I know there are a lot of variables that are very difficult to forecast or account when calculating depreciation, but some rough assumptions would be greatly appreciated.

    I was driving through Dublin Port earlier and got a look in the new car delivery lot

    Spotted a bunch of Maxus pickups, the T90 I think it's called. At least a dozen but maybe more behind them

    Demo models maybe, or something a county council might use?

    Not sure they fit in the with typical pickup drivers here who all seem to do high enough mileage

    If you're trying to predict the future, then I'd say the smartest option would be to take 2021 prices and apply standard depreciation for an ICE car to that

    Looking at prices for a 2021 ID.4 around 30-40% depreciation seems typical

    I wouldn't bother looking at prices for 2022-23, prices went insanely high for a lot of EVs and then with the price cuts over the past few months I'd say they'll see insane depreciation

    For example, and ID.4 Max was €57k when I bought it in 2021, then went to something like €70k, and now you're looking at around €50k for a similar trim (with a better motor and vastly improved software)

    100%, I think once you're likely to be staying longer than an hour or two then massed AC chargers makes more sense

    I saw the security guys in Carrickmines SC are using one

    Didn't know when I took the picture realised afterwards

    It does. But that assumes nobody wants to splash and dash and this setup will work for both scenarios.



  • Registered Users, Registered Users 2 Posts: 4,113 ✭✭✭wassie


    This is probably a good use case for the T90 - commercial lease, ticks the green boxes for corporate owners, lots of stop start all day tipping around the retail park, not needing to do any actual pickup 'work'.

    Otherwise the T90 its a very expensive piece of crap. Only thing going for it is there is currently no real alternatives at present on the market.

    I found this article to be a very interesting discussion on the EV market in China

    https://www.electrive.com/2024/05/04/electric-cars-five-lessons-from-the-motor-show-in-china/

    Quick summary, EU manufacturers are absolutely f**ked and have been completely overtaken on EV components and battery production

    One of the main things I've often heard about Chinese consumers is that they're more interested in digital features rather than drive comfort or range

    I never really understood it until reading the article, essentially many Chinese urban drivers spend most of their journey stuck in traffic so driving dynamics don't really come into play so much as in car entertainment

    You'd think they'd be promoting bikes or public transport over there but apparently there's a strong desire to exercise their newfound wealth from China's economic boom over the past decades

    Anyway, on the battery front it looks like CATL are completely dominating the market. The author was very pessimistic about EU manufacturers like Northvolt being able to catch up, particularly since many Chinese companies are setting up in Europe and will waterfall their manufacturing technology to those plants, giving them a tariff free option into the EU market

    The main question is which if the brands in china will survive the current price war there

    Anyone ever use the ESB chargers in Charlestown, mayo? I've a trip from Dublin to knock airport in a few weeks and ABRP is saying there are 200kw chargers in Charlestown, 4 of them. My car won't do 200kw but it sounds like a good charger!

    Ideally charge on the way to airport rather than on the trip back when we are tired and just want to get home but either is an option.

    Are they generally reliable and available? I can do the trip to knock and have 30/40% on arrival but won't get home without a 20 min charge or so. I've never used ABRP is it generally accurate?

    My experience of ABRP is that it was slightly pessimistic in good weather and I arrived with more battery than projected

    Aside from that, it's generally very accurate

    You can set preferences on networks if you'd prefer to use Ionity or Tesla networks, however I'm pretty sure there's no other hubs around that would be as convenient

    The Ecars sites you're looking at is actually 2x 200kW units with two plugs each, making 4 charging spaces

    If two cars are plugged into the same unit they'll get 100kW max each. I'm pretty sure those units can't intelligently split the load, if one side is pulling 50kW the other side is still limited to 100kW and not the remaining 150kW

    As such, budget some extra time for charging than what ABRP gives, since it will always assume you're getting the maximum available power from the charger

    It seems as good a location as you're going to get for charging near Knock, no risk of a single busted charger ruining your trip

  • Registered Users, Registered Users 2 Posts: 5,434 ✭✭✭Buddy Bubs


    Ah if I pull 50kwh for 30 to 45 mins while I get some grub before the flight I'm happy enough

    I normally don't care but I'll have the missus and her sister with me don't want to hear any complaints from them!

    I wonder what is the reasoning behind EV designs being so loud and scream 'I am driving an EV'

    The Ioniq 6 and Nissan Arya have to be one of the ugliest cars every designed along with the new Range Rover Sport and Mercedes GLC/GLE Coupe



  • Registered Users, Registered Users 2 Posts: 13,409 ✭✭✭✭prawnsambo


    They're not all like that, but yeah, I get your point.

    I'd say the primary reason is to reduce drag, ending up with very samey looking jelly moulds. Then there's the removal of the front grille as it's not needed and designers having all kinds of issues trying to design it out.

    Then there's the restrictions particular to EVs solely. Higher waistlines because batteries sit in the bottom, so you get some strange profiles.



  • Registered Users, Registered Users 2 Posts: 805 ✭✭✭CivilEx


    I have charged in Charlestown a few times. They are very new 200kW units, so quite reliable. Services are ok on site (SuperMacs, deli, etc). The last day I was there (about 2 weeks ago), there was some construction in the forecourt, but all four chargers were accessible. It's about 3 or 4 minutes off the N5, so would be a good choice for Knock Airport.

    If the four ESB chargers were in use and you were tight on time, there is also a 50kW EasyGo unit in Charlestown which is generally always available.

    I'd love to. Heading to Heineken cup final in London meeting their brother who lives in Mayo and flying from there. Bargain to fly from Knock actually, saving about 1200 euro between the 4 of us. Never flew from there before.



  • Registered Users, Registered Users 2 Posts: 4,113 ✭✭✭wassie


    Make sure you allow plenty of time from the car park, through check-in & security to get to the waiting lounge.

    ….Nearly took me a full 15 minutes last time.



  • Registered Users, Registered Users 2 Posts: 5,434 ✭✭✭Buddy Bubs


    I was thinking it'll be easier than Dublin airport alright. Might not even take me much longer to travel overall.

    As for herself, she drives an EV too and has only ever plugged it in once, very reluctantly, on a work trip to Waterford when we had only 1 car. That includes home charging. It's my job to keep them charged apparently ! Drives an EV, loves how it drives and knows zero about charging.

    I had to talk her through it and monitor the charge on the app from 200kms away while she constantly said I'll just leave now will I? No you'll leave when you've enough charge!

    That's why I know they'll be moaning if the chargers act up.

    If that happens, hand them the car manual…..😁
