    The 1 thing going against the M3 Services in Mulhuddart is it's a bit of a ball ache to get back on the M3 outbound from it... other than that, it would be a great location for a hub of some sort.. Catch a lot of inbound traffic visiting Dublin, and a nice top up before hitting the M50/City..



  • Registered Users, Registered Users 2 Posts: 11,939 ✭✭✭✭the_amazing_raisin


    I'd actually say Ballycoolin is the easiest to access from both directions. Mulhuddart is only really useful heading into the city, and a total PITA heading West

    That time of the year again folks, those of us with Night Rate need to change charging times over the weekend, going to Winter time of 11pm to 8am



  • Registered Users, Registered Users 2 Posts: 15,729 ✭✭✭✭AndyBoBandy


    Nah, my car is set to charge at 3am, and it’s always finished by about 7am…. Never have to worry about clocks changing!!!!!


    also, just on this, does everyone actually schedule their car to charge at bang on midnight/11pm to coincide with the night rate starting? I’d say it puts an awful strain on the grid if you have thousands and thousands of cars all suddenly pulling 7kW at that exact same moment!!!

  • Registered Users, Registered Users 2 Posts: 11,939 ✭✭✭✭the_amazing_raisin


    I've always just kept it in my head that night rates are between midnight and 8am. I lose an hour on one side but luckily it doesn't make a huge difference for me ye

    "While the network will be open to the public, Stellantis customers will receive “exclusive conditions” that have yet to be set out. Installation is to begin before the year’s end in Italy. Stellantis does not disclose more information on the schedule and exact locations."

    Might come here at some point?



  • Moderators Posts: 12,385 ✭✭✭✭Black_Knight


    Ah yes. Was in the back of my mind that was soon. I'll miss the early morning rush to get a wash and a tumble dry in before 9am. Always felt 9am was very late for what is an "off peak" rate. I kill charging at 7am here anyways. There'd be a potential for a perfect storm of car, washing machine, dryer, oven (mmmm scones) and a kettle to try trip the mains... again.



  • Moderators, Home & Garden Moderators Posts: 6,308 Mod ✭✭✭✭graememk


    At least here in Ireland our main fuse/breaker isnt the ESB fuse!

    Always seems weird to me, that watching electrician videos in the UK, the DNO fuse is the main fuse.

    Ha, yeah they'll put type 3c plugs on the chargers hand out adapters with each car so only stellantis cars can use them

    15,000 isn't that many when you consider the size of most European countries. France alone has 67 million people, so even 1% EV adoption and occasional public charging use would quickly overwhelm that network

    Got to thinking about home charging and the new big batteries that are coming on cars.

    As the owner of a Leaf24 with 6.6kw charging, I have no issue with overnight charging fitting within the cheap rate electricity time slot.

    But what about these new, much bigger batteries (not even sure what the largest battery available on a production model EV is now?).

    What is the max power that a home will allow an EV to charge at, without getting any special modification done to your electrical system at home?



  • Registered Users, Registered Users 2 Posts: 15,729 ✭✭✭✭AndyBoBandy


    Tesla’s have been coming with 100kWh batteries for years now.


    in reality though who’s going to be charging from 0-100% every night?


    night period is 9 hours, so you could take on 63kWh in that time. If you needed more in a single nightly charge, I’d say that’d be an outlier rather than the norm.



  • Registered Users Posts: 1,926 ✭✭✭Reati


    Most chargers will top out about 7.2kwh on a single phase connection iirc. You need 3 phase above that and that doesn't come standard and has additional install charges, work etc.



  • Registered Users, Registered Users 2 Posts: 6,887 ✭✭✭zg3409


    Beware the clock on your night rate meter can drift a bit over time, as in 10 or 15 minutes different from actual time. It's worse on older more mechanical clocks but the newer ones are supposed to get messages to correct themselves but some don't. Check the time on the meter versus your phone time. I typically set it to come on quite late for multiple reasons


    1) I don't want car sitting at 100% for long periods un necessarily

    2) Charging warns battery increasing range but battery cools after charging stops, so handy having warmer battery in morning.

    3) I have preheat cabin set to come on, the amount of preheat depends on the weather, but typically 15 minutes, I make sure charging is finished before preheat comes on. This also warms the battery and reduces the need for cabin heating increasing the range.

    4) I have charging set to continue way past normal say until 9am, in case battery is very, very low but also car equalises the cells when at 100%. Preheat can also drain battery below 100% as it takes more power than charger provides, so sometimes battery is 99% after preheat.

    I typically start charging at 00:25 or 01:25 until 09:00 which gives times for battery to fill to 100% no matter how low.



  • Registered Users, Registered Users 2 Posts: 11,939 ✭✭✭✭the_amazing_raisin


    It'd take 11 hours to charge my ID.4 from flat on the home charger, so it'll spill outside the night rate a bit


    As others have said, for now charging that amount daily is a bit of an outlier, so you can fill up the battery over a couple of days if needed

  • Registered Users, Registered Users 2 Posts: 34,041 ✭✭✭✭NIMAN


    What rate does your ID3 charge at? Battery size?

    Just wondering what you'd have to do to charge your car fully within the night rate, say maybe in 5 yrs time when big batteries are the norm?

    What sort of cost is involved to get a 3-phase install done?

    You’d never be charging from zero though. And very rarely to full. We charge to 80% except in hours before I commute to Dublin I’ll charge to 90% even though I don’t need to.


    this is our GOM with 80% charge now. (77kwh battery)




  • Registered Users, Registered Users 2 Posts: 34,041 ✭✭✭✭NIMAN


    I appreciate it you'll never be starting at 0% battery, but just curious about what charging speeds at home will be in the future?



  • Advertisement
  • Registered Users, Registered Users 2 Posts: 9,344 ✭✭✭markpb


    It’s hard to see home charging speeds exceeding 7kW in the near future. You can always pay ESB a small fortune to upgrade your home supply to 3ph, possibly replace your home charger to take advantage of it and you might also need a car that can charge faster than 7kW AC (like an older Tesla MS or MX with upgraded AC charger).



  • Registered Users Posts: 337 ✭✭Irishjg


    Surprising poor GOM for 80% of 77kwh. Roughly 61kwh. The Korean cousins Niro/Soul/Kona @ 64kwh will return circa 430-450km. I’m not comparing the quality of the cars by the way just surprised by VWs inefficiency. The Id3 is IMO a nicer car.



  • Registered Users, Registered Users 2 Posts: 13,652 ✭✭✭✭fits


    I do 500 km commuting a week of which majority is motorway at max speed. I get about 16 kWh / 100 km. I doubt the Korean cars would be more efficient. Perhaps a Tesla would be.


    edit sorry it’s 16.9 kwh/100 km on the commute.




  • Registered Users Posts: 2,146 ✭✭✭innrain


    You're in for a surprise. Kona is as efficient as the model 3. I commute the lenght of M50 with both of them and M3 is marginally better at higher speeds while Kona gets better at city driving. After driving 52.5k km on Kona the average consumption is 15. 3 kWh/100km while M3 after 10.5k km is at 14.8 kWh/100km but tesla didn't go through a winter yet. Also Tesla’s vampire drain is an order of magnitude greater than Kona's.

    EV database has a top of the most efficient cars

    Kona is one of the most efficient cars with large battery right behind Tesla.



  • Registered Users, Registered Users 2 Posts: 11,939 ✭✭✭✭the_amazing_raisin


    I think it's around €2.5k for the grid connection before vat and other works like trenching or infrastructure upgrades

    It might be worthwhile for folks renovating, I know of one or two people here needed 3 phase anyway for bigger heat pumps so they went with 3 phase chargers as well

    A lot of newer cars can take 11kW on 3 phase, so there is an advantage, but it'll never really pay for itself for EV charging alone

  • Registered Users Posts: 337 ✭✭Irishjg


    Your figures look very accurate to me Innrain. Spot on Sir.

    Absolutely no need for anything more than 1ph 7.2kwh charging for the vast, vast majority of users.

    8hrs at 7.2 kwh gives ~ 60kwh of charge. At 15kwh/ 100km, thats enough to get to Dublin and back from Cork.

    If you are doing that daily, you are probs a professional driver and will have 3phase anyway.

    You can actually get 11kwh from a 1phase supply if your charger and car support it which is even more than enough.



  • Moderators, Home & Garden Moderators Posts: 6,308 Mod ✭✭✭✭graememk


    No car here (in Europe) can charge at 11kw on single phase, no charger supports it nor does any cable.

    There is a 48amp option in some cars in the US I think



  • Registered Users, Registered Users 2 Posts: 424 ✭✭Roger the cabin boy


    Audi's compact charging system has a 1ph, 11kwh version.



  • Moderators, Home & Garden Moderators Posts: 6,308 Mod ✭✭✭✭graememk


    your gonna have to cite some references there. Unless its using an inverter to change the singe phase to 3 phase, 32amps is the max for chargepoints and cables, In europe.



  • Registered Users, Registered Users 2 Posts: 424 ✭✭Roger the cabin boy

  • Moderators Posts: 12,385 ✭✭✭✭Black_Knight


    The math on 3phase (if it costs €2.5k) could be worth doing if these stupid smart meter rates stay as they are. Only 2 hours of cheap electricity overnight, vs the current 9. Or 9 hours of night rate, but at ~ 12c/kWh.



  • Moderators, Home & Garden Moderators Posts: 6,308 Mod ✭✭✭✭graememk


    Ah thats the Portable charge point (like a beefed up granny cable). I also think its only for the North American Market, where they dont have much three phase power but really beefy split phase 120/240 (in some places). - I dont think any Etrons in europe charge any faster than 32amps.

    I think you can get charge points over there all the way up to 70amps, but the car needs to support it too. The car physically controls the power, not the charge point. It only does the signalling.

    The 32amp isnt a limit on the connector, but more of the cables to and from the charge point. (the AC only Zoe's can charge at 43kw on AC, but i dont think you can get them anymore, and the rapid AC is being phased out)



  • Registered Users, Registered Users 2 Posts: 424 ✭✭Roger the cabin boy


    Hmm. Fair points.

    The info on this stuff takes quite a bit of weeding out i find.

    I see no reason for a 7.2kw limit domestically. My shower is ~11kw. Granted, its on the CU side and doesn't run for hours at a time but with proper design, it really shouldn't be an issue.

    Still, i think going forward, eventually, batteries will be fine with (commercial) high power DC charging and domestic charging will become a luxury rather than a necessity, used for trickle charging. It's a fascinating scene atm.



  • Registered Users Posts: 2,146 ✭✭✭innrain


    I don't think bigger is better will continue going forward. If I'd make a parallel to the semi industry in the 90s there was a race on the number of transistors on a chip and high clock speeds. After 00s they realised thats not all and went for refinement resulting in more efficient use of resources. And finally the winner technology ARM is way less powerful but way more flexible and efficient. Going back to the cars, now that EVs become mainstream there will be a race on their efficiency. 7 kW means 40km/h for me and if I use that 8h every day that's over 2000 km a week. Every % increase in the efficiency would make this figure even bigger.



  • Registered Users, Registered Users 2 Posts: 11,939 ✭✭✭✭the_amazing_raisin


    Yeah I feel like people who think mainstream EVs are going to have 200kWh batteries are dreaming.

    Even if all the upcoming battery technologies pay off it'll likely translate into smaller lighter batteries for most cars rather than more capacity 

    I think 50-80kWh is going to become the norm for most cars for the next decade. Most people are fine with a car that will go 300-400km between charges. Bigger batteries will be reserved for the luxury segment

  • Registered Users, Registered Users 2 Posts: 1,292 ✭✭✭MightyMunster


    Hopefully you're right, no need for 90% of people to have a battery bigger than 50-70kwh in Ireland anyway.

    Mine is only around 50 and can get anywhere on the island with one stop, which I'd do anyway if driving over 3 hours



  • Registered Users, Registered Users 2 Posts: 1,079 ✭✭✭Comer1


    I have no problem with one or two stops on a journey, but I would have a problem with waiting an hour in a queue for a charger. The public fast charging network is the weak link in all this and EV sales are increasing way faster than the network, so things are only going to get worse.



  • Registered Users, Registered Users 2 Posts: 22,236 ✭✭✭✭ELM327


    I think there may be a move to 11kW for some folks, particularly rural.

    It's the norm in some EU countries already. If I have 2 Evs I'd like the option to charge both, or add 9*11 99kWh overnight in some breakdown. EG 60kWh for a main car and 40kWh for the second.

    I accept we're an edge case but there's probably a few rural dwellers like us that do 50k plus in a year.

    Actually, hold that thought, if I were installing 11kW I'd just install a single phase 7.4kW and a single phase 3.7kW instead.



  • Moderators, Sports Moderators Posts: 19,197 Mod ✭✭✭✭slave1


    We are two EV household, we just chat as to who needs to use the charger what night, it's never been an issue in 4+ years. We have Zappi and worst case scenario an outside socket to granny charge but the need has never arisen



  • Registered Users, Registered Users 2 Posts: 22,236 ✭✭✭✭ELM327


    Not sure I'd like that but maybe it's just anxiety on my behalf going from a one to a two EV household. We've had 4 EVs so far but never 2 at the same time. Early next year we'll likely be a two EV household and I was thinking of getting a 7kW home charger and a 3.7kW CEE plug.

  • Registered Users, Registered Users 2 Posts: 12,136 ✭✭✭✭KCross


    Nothing stopping you having two EV's charging at the full 7.4kW each all night long. You just need to have the enhanced electricity supply of 16kVA and then ensure that the charge points are load sensing just in case something else like a kettle comes on for a few mins, but you can easily get your proposed 99kWh on a single phase supply overnight.

    If needs be you can even go up another notch to 20kVA.



  • Registered Users, Registered Users 2 Posts: 22,236 ✭✭✭✭ELM327


    I'd be concerned with 7.4kW + 7.4kW running on a 16kVA setup, there's only a 1kW "buffer" and I like to run everything at night, dryer dishwasher etc.

    If we end up getting two EVs I may scope out the cost of a 20kVA upgrade. I know the 13 to 16 is not a substantial amount cost wise but I suppose the 20kVA is more chunky

    EDIT: seems to be "€2,717 + MV Network Charges"

    in the event of a power cut can you run a cable from an EV into your house , through an inverter to keep a few plugs going? our house had a powercut because of a road side fault a few weeks back , I wouldn't mind having an option or 2 if it happens again

    The new ioniq5 supports 16a V2L. In order to use this for the house, legally, you'd need an isolator switch to disconnect the house from the grid and a blue CEE 16a connector for the house.



  • Registered Users, Registered Users 2 Posts: 18,691 ✭✭✭✭silverharp


    I saw some articles alright about by directional tech in the offing, I just want to run a cable through an open window and keep a few gadgets going in the living room, last time my kids were on the verge of moving into the car lol

    Heating circulating pump, broadband router and a few lamps. It would be a very handy option to have on the BEV alright.



  • Registered Users, Registered Users 2 Posts: 12,136 ✭✭✭✭KCross


    Just use load sensing charge points. Its almost standard on new charge points now.

    You have 15-20A to spare when the two cars are charging and you have 9hrs to get your 99kWh. Easily achievable, even if you leave to go to work before night rate ends.... could be done in 7hrs even.

    Dishwashers etc are not a big deal. They only heat water for a very short period of time during their 2hr cycle and the charge points can ramp down by 1kW to allow that to happen for the few minutes it takes them to heat the water. The rest of the wash cycle is only a few hundred watts. Not a problem.

    Basically, you dont need more than 16kVA to get 99kWh's into your cars overnight.

    In Europe, The PHEV variants combine the 3.0-liter inline-six engine and a 38.2-kilowatt-hour lithium-ion battery (31.8 kWh usable). The 141-hp (105-kW) electric motor integrates into the transmission. The P510e PHEV gets to 60 mph (96 kph) in 5.3 seconds or 62 mph (100 kph) in 5.6 seconds. Land Rover estimates a WLTP range on electric power of 62 miles (100 kilometers) and a real-world range of 50 miles (80 kilometers).


    That's some battery for a PHEV, is there any other PHEV with a larger battery than this?



  • Registered Users, Registered Users 2 Posts: 22,236 ✭✭✭✭ELM327


    That's insane. More usable energy than my ioniq28. And it takes CCS.
