    This is precisely what I'd expect from modern EV tech in 2023....

    The tide does indeed come and go twice a day, but for 1-2 hours either side of turning, it’s very slack, so in a 24 hour period, you are only getting maybe 16-18 hours of full flow, with the rest of the time being very slack and not able to produce anything….

    Tidal seems to make sense for anyone who has ever stood in the sea and was knocked over by a wave. All that energy, all the time, everywhere where there's a coastline, for free. But it has been tried many times, failed every single time even before it got tried at commercial scale. Forget about it.

    I did over 500km 5 years ago in an ev with 2 stops and a quick splash and dash. And I was doing 120 plus. Dublin to cork to Dublin EV rally. We only had SPOF 50kW chargers then, and I couldnt afford a Tesla then so I was in the poor mans tesla (Ioniq28!).

    Now, in 2023, that should be easily doable on one 10-15 minute stop. Just avoid ecars. All motorways in Ireland seem to have great coverage. Even removing superchargers, I'd be able to do that drive at 120+ in my base model 3 with one charge.

    Wave and tide are different things.

    Wave generators need rough seas. Plenty of small demos but no large scale.

    Tidal generators tested in Carling Ford lough. It's basically an upside down wind turbine. They designed it so everything can raise out of the water for repair and inspection. It peaks at predetermined times each day. There is only limited places around British isles where they could be used usually in estuaries.

    Salt corrosion, moving parts, limited locations, but mainly higher cost than wind.

    Shore based wind is proven financially viable and breaks even in around 5 years. Offshore less so but still massive strides and plans for big areas like Dublin Wicklow and Arklow planned.

    No need to reinvent the wheel.

    I charge only at public chargers and I deliberately don't use ESB DCs. From a frequent user perspective for 13 quid a month I have access to Ionity at 35c/kWh which is cheaper than the daytime electricity at home. (not to mention cheaper ESB rates). Then you get multi chargers per location which actually deliver power. I have not used an ESB DC other that for testing purposes since May of 2021. I never drive under the speed limit, and the climate is set to 21 Celsius since I bought the car..

    Now I watched the video and my conclusion is that it is trying to show the perspective of a completely novice, noob is you want, at EVs, charging and all that. I think it is a genuine thing, and shows the effort required to educate people when getting into an EV. Unfortunately he's right the infrastructure is not there but also the mindset needs to change. At around minute 5 they say they have stopped at Cashel for number 1 but didn't charge as they have only an esb card. Personally I would have charged there and went directly to the airport where I would have charged to 100% during the 2.5h stop. That is the biggest change in mindset that the EV drivers and charging networks have to do. Charge while parked is a great advantage the EV ca get. You don't need to go to a petrol station to get electricity. Case in point, Cork airport has a number of DC and AC chargers. Why not charge there? The piece at J14 shows how poor the only ESB hub is. Mind you the last unit the Delta was brought in last as the efacec never worked properly. Ionity is waay better bet. Why was that required I don't know as never drove a Mustang EV, but my car is at 25% now and it reports 131km range. From J14 to Dublin is around 70 ish? I would definitely get home without stopping so again a novice perspective. Yes, Mark we want more videos like this but a little bit of planning doesn't hurt.

    To me the dream scenario is a floating wind turbine with a tidal or wave generator under it


    Probably a whole heap of good engineering reasons why it won't work very well or be cost effective.

    But combining both generation methods in the same site and through the same grid connection seems like a cool idea

    I agree there's definitely some steep learning curve which I think puts a lot of people off. The total lack of good information isn't helping

    For example about a year ago I was chatting with a woman who had just gotten an EV6. She was saying the salesman told her that driving up North is easy and there's a fast charger in Castlebellingham

    Yeah, THAT Castlebellingham 🙄

    Anyway she tried it out with her other half and they were unsurprisingly annoyed to see the massive queue at the ESB charger


    I mentioned to her that there's a much faster Ionity charger at City North and she said she had no idea it even existed


    You'd think the Kia sales team would know about Ionity since their parent company is one of the owners 🤦‍♂️

    So there needs to be some general advertising around EV charging I reckon. There's billboards advertising cheap fuel, why don't we have a big billboard on the M7 saying "Ionity, Ireland's fastest charging network, located at Kill and Cashel" or something like that?

    ESB certainly has its issues.

    But I suspect the biggest issue from the off is the Mustangs obvious horrendous inefficiency on the day.....

    The ESB chargers would have been okay from an impact on the test prospective had the EV been an efficient one.....

    Inefficiency on an EV means more energy is needed to put mileage back in the battery....

    Thus more time at chargers.

    Edit


    For context......

    It appears the one in Cork* can do between 85 and 126 kW.

    An MG5 should be able to put in 152 miles in 40 mins at 80 to 90 kW.....

    That's after doing potentially 160 miles to the charger.

    Giving a potential mileage on one charge stop of 40 mins of 312 miles.

    I get the point that the MG5 may not perfectly hit that projected performance on the day of the test.

    But could still match or even beat a car with much higher peak charging speed and a much bigger battery.

    Efficiency for the win....


    *the one used on the day

    We should also look at more pumped hydro storage (they are the batteries)

    Funny you mention that - I was reading up over the weekend about the Snowy 2.0 pumped hydro expansion project currently being built in Aus.

    Snowy 2.0 will provide an additional 2,000 megawatts of dispatchable, on-demand generating capacity and approximately 350,000 megawatt hours of large-scale storage to the National Electricity Market. To provide context, this is enough energy storage to power three million homes over the course of a week.

    Thats a big-arse battery....

    inefficiency and a seemingly woeful charging curve!



  • Registered Users, Registered Users 2 Posts: 1,510 ✭✭✭cannco253


    The first platform allowing access to Tesla’s Supercharger charging network is Chargemap. Owners of a Tesla or other EV can now use their Chargemap Pass to charge at a Supercharger. The service is limited to France for now. Still, the compatibility of the Chargemap Pass will soon be extended to all Superchargers approved for all-electric cars in the rest of Europe.



  • Registered Users, Registered Users 2 Posts: 5,128 ✭✭✭budhabob


    Is it limited to certain chargers at a hub or will the entire hub be opened up? I would hope for the former to keep the USP for teslas.



  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,264 Mod ✭✭✭✭liamog


    There's a thread for the Supercharger network https://www.boards.ie/discussion/2058155111/tesla-supercharger-network-in-ireland. Short answer to your question is when they open a site it's the whole site. Nothing announced or opened up in Ireland yet.

    Just a gentle reminder to any new EV drivers.

    If you park at a charger and don't plug in, you are blocking that charger from being used by someone who may need it.

    I was charging at the chargepoint outside Dealz in rathfarnham recently. Even though it has 2 connectors only one works at any time. A lady pulled in beside me so I jumped out to tell her that her side wouldn't work while I am actively charging. She replied "oh I'm not charging. I just park here to do my shopping". I told her it's the same as blocking a petrol pump and leaving your car there. She just went "yeah I suppose so", and then walked off and left it there.



  • Registered Users, Registered Users 2 Posts: 23,109 ✭✭✭✭ELM327


    It does do 2 at a time there, I'm often there and have no issues charging when another is actively charging. I even checked and we were drawing 11kW each!



  • Registered Users, Registered Users 2 Posts: 4,117 ✭✭✭wassie


    Clearly couldnt charge 2 cars when @mfceiling was there!

    I suspect that driver switched from disabled car bays to EV bays when she got a new set of wheels.



  • Registered Users, Registered Users 2 Posts: 12,990 ✭✭✭✭mfceiling


    Wouldn't work for me on Monday. Once one car was charging it wouldn't start a charge on the other side. Happened a lot there recently.



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


    Typical southsiders, not a moment's courtesy for the common folk 🙄

    Fair, I do see site limitation at times there, sometimes the chargers are limited to 3kW each side. Strange setup. I have been there recently with all 4 in use though. It's one of my favorite park and charge locations as there is a tesco and dealz on site so good for doing the shopping if I'm in dublin.

    Agreed - it is very easy to miss the turn off for the Ionity chargers at Kill North and South.

    I often wondered why there isn't a large Ionity sign just before the turn-off.



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


    I guess it's to do with the fact that they're renting the land from a forecourt operator. The likes of Circle K might not want to advertise a charging network which will likely be a competitor in the next few years


    I wonder will this change with Ionity going for bigger hubs like Mornas which have a shelter and a big Ionity sign on the top


    It'll be a long time before we see that in Ireland however

    Call the council and ask them how much is the yearly cost to put a sign up on the motorway.



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


    I'm going to go on a limb here and suggest that it's probably cheaper than a 1.5MW grid connection 😉

    How long after the grant is "granted", do they send you the money? Got notification Monday



  • Registered Users, Registered Users 2 Posts: 9,433 ✭✭✭markpb


    TII won’t give permission to put advertising signs along a motorway. (I’m not sure about their policies for Dual Carriageways like the N7.) That’s why you see advertising painted on the side of trucks parked in a field.

    RTE news : EV sales on course to deliver 'a step-change' in 2025


    Trying to figure out if the guy from SEAI is a genius or an idiot.

    He claims the charging network isn't holding back EV adoption, 80% of charging will be done at home and drivers will only be stopping for short breaks to charge.

    He also said that someone could drive from Dublin to Mayo and potentially back in one charge


    I'd say the last point is pretty optimistic, maybe in a Model S in the height of summer but pretty much everything else will need a top up

    I think he's correct that the majority of charging will be done at home. Although unless there's major changes to allow people without driveways to install a home charger then that "home" charging will in reality be public charging, in which case we're back to needing hundreds of thousands of AC chargers

    I very much disagree that the charging network isn't holding back sales. As has been discussed before, Ecars have zero ambitions regarding the charging network and seem content to roll out inadequate facilities and call then hubs. Seriously, boasting about a 100kW charger in 2023 🙄


    More players are joining the game but we've seen from Applegreen that installing chargers and then getting power to them are two different challenges

    And compared to the scale of the hubs being installed in the UK and Europe, ours are just way behind.

    I mean, we're getting excited about 2 chargers at Castlebellingham and a 6 car hub in Belfast when there's a 20 car BP pulse hub just opened in the UK and two 16 car Ionity hubs just opened in France

    Tesla at least seem to be willing to install decent hubs in Ireland, Ionity seem to treat us like the forgotten child

    I've no doubt the network is improving but I think there's a lot of people hearing horror stories about queues and are deciding to hold off for a few years

    So I guess my conclusion is that he's an idiot 😬

    I'm going to go even further out on a limb than before and suggest that painting "Ionity, high speed EV charging, located at Cashel and Kill" on a couple of trailers and paying to park them in a few fields along the M7 is definitely cheaper than getting a 1.5MW grid connection 😁

    And it won't take 3 years either waiting for the ESB 😂

    I think his dublin to mayo and back is a specific reference to a recent EQS coast to coast video from Derek Reilly where he said he could go coast to coast to coast in it
