Could you PM me your insurer? We had to pay an additional €162 on top of our existing €411 premium when we switched from Ford Fiesta to Ioniq 5 exec plus….

Hi, no need to PM you. It was Aviva. Had to speak to them on the phone as Ioniq 5 was not on their on line list, eventually got onto a very helpful lady. We have many policies with same insurer over many years..

So do we have another full electric household (ID.3 & Ioniq 5)?

Yes, why aren't you paying attention..😁. We have been full EV household for a while now, the missus traded in her old Ioniq classic about 3 weeks ago.

In centerparcs at present. Brought the ID3. Started out with 100% charge and got here with 65%. Won’t even need to charge here or on way home. It’s a great car. The only thing I’d like in it is a bigger boot.

Ha, I didn't realise you had the Ioniq before as well. I haven't been logging in for about 2 months to be fair

I'll confess I do feel a bit smug driving past the petrol station these days and seeing the horrendous fuel prices. Nice not to have to worry about that anymore

The recent hikes in electricity prices however...

This.

And yet we all have those friends or work colleagues who say, "oh I couldn't get by with an electric car", despite never travelling outside of their town or city for 95% of the year.

I suppose the price per km from 1c to about 1.1c is almost bearable, lol 😏

If you did need to there is a bank of 4 chargers in the car park

Yea youtubers can be annoying it all about the money and subscribers.when should be about the videos and entertainment with there subscribers.

That not to say there all like that.

Yeah we saw them but honestly don’t need it. And don’t want the hassle of moving the car again after charging. Be grand.

I heard a good explanation of it a while back. Basically they don't get money per subscriber or anything, but having more subscribers gives them more pull when trying to get press cars or invitations to events

It does also put them on the radar for more sponsorship deals. Some of them are fairly shameless about who they'll take money from to do product placement (for example a certain car repair guy selling headphones and beard trimmers).

Others seem a bit more discerning, Bjorn for example won't do deals with any car companies and tends to focus on brands that are useful to EV drivers (although Stormbeg is a bit of a stretch)

So yeah, the whole like and subscribe thing gets fairly annoying, especially if they keep asking through the video. But since YouTube is basically one giant popularity competition, it's pretty understandable

I ended up charging the ID.4 on the last morning. I'm pretty I'd have made it home with plenty to spare, just the old Leaf driver paranoia kicking in 😂

One tip, turn off the departure timer while you're there, cuts down on the vampire drain. Or turn the temperature down to something minimal

I've had a Zappi v2 installed since August 20 and haven't had any problems with it.

Over the last 2 or 3 months I've started to notice a few appearing at houses in the area, alongside a new EV.

I live in a cul de sac of 15 houses, nobody has 3 phase. What would happen if every house had a charger installed, and each house was charging simultaneously? Would their be some sort of power limitation to the area given the amount of energy being requested and consumed?

Yes, is the short answer.

It is known that parts of the network will need to be upgraded as we progress to more and more EV's and heat pumps. It will need to be done on an as needed basis. Not as much in housing estates but more so in rural areas where one transformer could be feeding 5 houses.

Each house is connected to a transformer and ESB can roughly tell when a transformer is being overloaded. They wont know exactly when everyone is charging their cars but they'll know x kWh's is going through that transformer so they'll have an idea and you'd probably start seeing lights flicker etc. One call to ESB and they'll check if an upgrade is required and that will be that.

I would say a cheap one as depreciation may be highest cost for EVs. If used very little you should lift wheels off the ground, and shield tyres from direct sunlight. Tyres will crack and get flat spots if left sitting Make sure tyre pressures are high. Ideally keep indoors in a dry garage. In terms of main battery some cars you can limit charging to say 70% and so then leave car connected to the charger. You might want to disconnect the 12 volt, or put it on a good trickle charger or bring it indoors to keep the frost away from it.

I don't know if any brands are better than others but Tesla tends to look after main battery and 12 volt battery well, any car with connected app will at least allow you to check status so you don't arrive to car with flat 12 volt and flat main battery. Teslas tend to drop 1% per day, so you might need to keep charger connected. With a remote app you could fill to 100% before you arrive, although the leaf might be able to do this, but the non 100% option is not on later models I believe.

In terms of depreciation an old 500 euro banger car may be less risk and cost to leave sitting parked up. You can declare off the road to not pay road tax for one calendar month at a time with minimum 3 month re-tax period. Older cars (over 10 years) would need an NCT every 12 months.

In the short term no, instant showers take more than EVs, people throw on their kettle, electric cooker, washing machine, it's really only peak times 5pm to 7pm where problems might happen, but EVs can easily load balance and charge at night. In the UK all new home chargers must be internet connected, and medium term the plan is to send out a signal to delay charging at peak overload times. In the long term car to grid systems means your house has a 50kW battery to help balance the grid, in the form of a car, and so plugged in EVs gave massive potential to soak up excess wind at night, and feed back to grid at peak times. Smart meters already penalise energy usage at peak times in terms of cost most high mileage EV commuters already use night rate times.

Theo e away from gas and oil to heat pumps will have a bigger impact as they may be operating 10 or 20 hours a day, but they will probably switch off at peak times and ramp up and cheap times

Everyone doesnt take a shower at the same time though and they only last minutes (same for kettle etc). The question is around EV charging which will all happen at night at the same time and for hours at a time so lots of overlap.

What you are referring to is max grid issues but the question wasnt really about the overall grid, its about the individual transformers on his cul-de-sac being overloaded. Smart meter's wont solve that. ESB have said they will need to upgrade parts of the network on an as needed basis.

His example.... 15 houses in a cul-de-sac. If even 10 of those are charging at 7kW's each at the same time, what will happen? Very hot transformers and low voltage is what will happen! :)

The transformer(s) will need to be upgraded.

 In the long term car to grid systems means your house has a 50kW battery to help balance the grid, in the form of a car, and so plugged in EVs gave massive potential to soak up excess wind at night, and feed back to grid at peak times.

V2G is a long way off in terms of general rollout. Its proven tech but not ready for prime time.

"None" of todays EV's support that (a couple of exceptions) and by the time it becomes common you will have 000s of people with cars and charge points that dont support it and reluctant to shell out more cash for it. It will happen, but it wont be everywhere in the medium term.

Yeah, I've accepted the fact an EV probably won't work. We're buying a holiday home abroad, and would love to have a car based there, but it could be left sitting for up to 6 months at a time..

edit: and the house is coming with a 5kWp system!

For longer summer trips we'll probably be driving there from Dublin (2 Ferries & 1,800km drive each way, or 1 ferry & 2,800km each way), but for other shorter trips, having a car there would be mush easier. I have an old ICE here I could bring over and leave there, but long term it'd probably just be less hassle to have a LHD car... I did see a Model 3 for sale for €33k (which would be way too expensive for me anyway!!), but it's an American import with the Tesla charge port, so charging it would be a pain in the arse! (not sure if you could retrofit a CCS2 onto an American Model 3).

I think picking up an old ICE over there is probably the best bet. Would have loved a little EV for there as it's mostly still free charging (AC & DC).edit: and the house is coming with a 5kWp system too!!

Showers don’t last for several hours. The two are not comparable, you can overload circuits for short periods.

What happens during the world cup Ireland matches at half time when everyone puts on kettles at exact same time?

Supply to most houses is 60amp, an EV only takes 32 amp max. So even if one EV at every house, it will only be 50% of planned capacity and at night time cookers and showers won't be running. I just think the issue is overplayed, as a downside to EVs when in fact it may be great for the grid. No one cried wild when people installed 40 amp showers , and then put in a second 40 amp shower like half of houses around. Sure upgrades may be needed but typically that's a new local substation that may be old anyway. Heat pumps will have a bigger impact. Load sensing and smart chargers are only shortly away from being a reality. Trials already happening in uk

See this link

https://insideevs.com/news/537120/ev-chargers-switched-off-uk/

While this may seem like doom and gloom it's actually great for the network, users can over-ride the request, and it will only be for a short period if needed. Similar could be done today with immersions. Solar PV prices are also dropping like a stone and some EV owners fill from the sun. Already heavy users such as steel plants agree to short power cuts in exchange for lower prices

ELM327

Smart chargers in the UK are flawed as a power control, people already state on the forums that they simply remove the internet connection after the install to avoid any control over charging.

If there's ever anything like that brought in here, I'll simply get a 16a and 32a CEE plug installed. Dumb 32a plug, cheaper than the EV charger (as the EVSE would be in the cable) and not subject to any regulation.

Same reason I'll never get a smart meter. Simply doesnt benefit me to do so.

The people on forums are almost inevitably in the minority. Most people won't know, won't care and won't touch it and as long as the majority do that, the system could work as planned.

You'd be surprised how this stuff penetrates into the public mind and get twisted. Honestly it seems kinda messed up that a law can come into force requiring you to allow remote access to control how power is used in your own home.

You have a major flaw in your thinking. You are looking at the overall grid, not local.

Your house fuse might be at 50% but the transformer is shared across several houses and has diversity built in so its not sized to give every house 60A at the same time so it could be on fire outside if everyone connected to that specific transformer and charged at 7kW at the same time! :)

I'm being facetious there but my point is, the question that was asked was about local restrictions, not about the overall grid.

What happens during the world cup Ireland matches at half time when everyone puts on kettles at exact same time?

A 2min boil of several 2kW kettle at a local level will be fine. 7kW continuously for hours is a different prospect entirely.

I just think the issue is overplayed, as a downside to EVs when in fact it may be great for the grid

I agree it gets overplayed in terms of the "grid collapsing due to EV's". Loads of spare generation capacity at the grid level at night and as you said it has some significant positive sides but again the question wasnt directed at the grid level but more the local level so I think you are answering a different question.

Another thing, even if we have more EV charge points at home, it's not as if they will all be on charge every night, with greater range this is now not required and there's plenty of folk with no idea on night rate etc who will be charging during the day

Totally true. I was once told never underestimate how lazy/complacent/stupid the "general populous " is. Evidence of this is how a friends sister got a tesla, and just plugged it in at home without thinking about shopping around for electricity. €900 bimonthly bill later and they are confused about these savings that can be made on an EV.

nothing wring with feeling smug.

youd be surprised to see how many people can afford an EV but don’t realise.

my monthly repayments are cheaper than my monthly fuel bill on my old 2006.

the Savings on motor tax alone pays for 2 months repayments. Saving on tolls and insurance another month.

savings on maintenance another months.

so at the the end of the year it’s cheaper
