Random EV thoughts.....

witnessmenow

I made a couple of quick features on a telegram bot for Ev related stuff just so I don't have to do maths anymore

1. Calculating how long the battery will take to charge. You pass in the current SoC and it calculates how long it will take to charger to a few different levels, basically to see if we need to increase the charging window outside the 3 hours Ev rate. (you could possibly get the SoC from bluelink directly, but I don't want to stress the 12v battery!) Our car charges at roughly 15% per hour
2. Not directly Ev related, but calculating how long to delay the washing machine/dryer/dishwasher to get it on the night rate/Ev rate.

I'm running these on my home assistant instance so I'm happy to share the code if anyone else wants to set them up on theres

I'm going OT here, but this is something that really bugs me about Dublin Airport trying to increase its passenger cap

The airport terminals are already jammed up most of the time, allowing more passengers through is just going to stretch the capacity more

There's other airports in the country, I'm sure they could benefit greatly from some investment and shifting some of the extra traffic over to them. It would suit a lot of people outside Dublin as well since they don't have to deal with a long trip to Dublin as well as the flight

I'll also be upfront, it would benefit me personally to move some traffic away from the airport since I live near it and less aircraft noise or air pollution would be a plus

Like everyone else in the area, I was aware of the realities of living near an airport, but DAA have been taking the piss since the new runway was finished. Their projected noise pollution was a complete fabrication and their attitude towards residents seems to be "f**k off, none of ye matter anyway"

yer man!

Charlestown stop is brilliant for charging, charged there in February and had no issues. On my way home though I stopped off again at around 6pm when Supermacs got really busy and one of the spaces were ICEd. The parking in general at the site is not sufficient.

I'm currently in Lithuania, and there was great buzz here as 2 CyberTrucks were spotted on local plates…

But it turns out someone was trying to import them into Russia from the EU via Belarus to try and get around the sanctions… but the Lithuanian border guards were wise to it as it's a fairly common route for high end cars leaving the EU and eventually finding their way to Russia…

Small sample size but it does provide an indicator to understanding why many people continue to resist the transition to EVs. Basically a lot of people simply resist change and will continue with what they are familiar with for as long as they can despite the browbeating by the enlightened. PHEV anyone…

Tells everyone she is driving an EV but wouldn't be the best ambassador for them if asked questions.

Range? Well I once went to Waterford and had to charge for 30 mins in Kilkenny on the way back until got a call it was ok to leave. Think he brings it into work about once a week to charge, I don't know how much I drive though.

Battery size? It's big, it's the entire floor of the car.

She'll tell you it's fast though and takes off like a rocket

Genuinely does like them but has no interest in what they are or how they're put together. No trips to petrol station is a huge factor for her though. And absolutely loves the Etron over the cupra more than I do I think.

My missus had a 28kWh EV about 6 months before I got my first one 4 years ago. She regularly used to visit our daughter in Dublin from rural Co Wexford in it and she aint slow🙂. Usually over night so a bit of Granny charging before returning.

She was asked if she ever got Range Anxiety, her reply was no, that she leaves that for me at home.😋

my mrs isnt too bad and has stopped at an ionity once herself. She drives more than i do so makes sure the car is charged once a week or whenever needed. She too is a big fan of never needing to frequent a petrol station.

Maybe start a new thread on this. One thing to note is that if your charger has load sensing it will reduce the rate while everything is on at the same time.

Recently I have been watching my home load on solar, EV, washing machine, electric oven etc. The washing machine only draws a high load for the first 10-20 minutes as it heats the water, after that it's low power usage rotating the drum. Similar with dishwasher. So real world only factor in washing machine load in first 20 minutes. After that power will be freed up for car charging. Dryers tend to take full power all the time. Ideally you want to keep house load at max 50 amps, even though fuse is 60 amps the continuous rating of supply to houses is 50 amps. You can usually set up grid limit on charger.

With free solar daytime I stop the dryer to boil the kettle to maximize free power!, I do have automatic load dumping to hot water, underfloor heating, EV charger etc. I don't get any money for export at the moment and I have 9 hour night rate with dumb meter.

My wife took my car to work one day. Battery was low and she had a fair bit of driving later in the day.

She rang me from work looking help to charge it. As she was on the phone a guy she works with got out of his 330e BMW. Fair play to him, he showed her what to do. I was still on the line and I could hear her say "what do I do now Dave"?

"Go inside and do some work" he says 😂.

She rang me later that day in amazement. "The car is on 75% battery now. I've loads of range for my journey".

I think a lot of people don't realise that the majority of time, your car, be it petrol, diesel or electric just sits there going nowhere.

For many people a car is one of the most under-utilised things they'll ever buy, and yet our world is such that you need one

Sabine Hossenfelder no longer believes EV's are the answer, so she bought a hybrid.

Same line of thinking that has me wondering how building 10,000 km of high voltage power lines criss crossing Australia to connect renewables can be either eco or cost effective, which is the current estimate.

I have no idea who that is nor care anything for her opinion.

I investigated. It's the flimsiest reason imaginable: There won't be enough grid energy. She even admits that there are new renewable energy projects ready to go, but they're not yet connected to the grid and this is a major problem for 2035. Like WTAF?

The same arguments were rolled out when streaming services started. I suppose we won't have them by over a decade ago either.

To meet national climate targets, grid investment needs to nearly double by 2030 to over USD 600 billion per year after over a decade of stagnation at the global level,

For Australia to roll out renewables and connect them will need at least 10,000 km of additional transmission lines.

It's quite bonkers when there is a thread derailing alternative that is far cheaper.

NASA just named an asteroid after Sabine, which is cool.

Forgetting the fact that the roll out of renewables has to happen anyway. Supposedly intelligent people wallowing in their own poop here.

Australia has already explained why that alternative won't happen.

https://www.climatecouncil.org.au/nuclear-power-stations-are-not-appropriate-for-australia-and-probably-never-will-be/

As regards the 10,000km of new lines, that's not a particularly big number for a country the size of Australia with a dispersed population. And much of that will be through territory where there won't be the same problem getting planning permission unlike here where it can take decades to get one new transmission line approved.

And your energy market operator CEO has said:

“There is no doubt renewable solar and wind generation are the cheapest replacement technology for those retiring coal power stations, even taking into account firming and integration costs.

Nuclear is about the most expensive form of new to be deployed electricity generation. Along with coal. No smart state will ever start to plan to build a new nuclear plant again. Get with the times dude. I've never been opposed to nuclear, but the horse has bolted on that one.

You are totally and completely wrong, nuclear is far cheaper than renewables if you buy Korean APR-1400s from Korean Hydro and Nuclear Power, which have recently completed two reactors at Shin-Hanul power plant in S Korea and are currently building units 3&4. They just offered to build 6 for Poland at the same price as those two. In addition to the four they built for the Barakah NPP in the UAE, which came in at a bit more per GW than the other examples I mentioned, but still way cheaper than the cost of OSW off Scotland in the form of the recently completed East Anglia One and under construction Dogger Bank - the world's largest OSW farm project.

East Anglia One cost $4.37 billion per GW of capacity, Dogger Bank is costing $3.12 billion. While the Barakah NPP cost $4.36 billion per GW and the Shin-Hanul/Polish price is $3.18 billion per GW.

The reason I said far cheaper is that the OSW mentioned has a capacity factor of around 47% while an APR-1400 based plant has a 96% capacity factor. You need to double those OSW prices to even begin to compare like for like, let alone add the cost of battery/hydrogen/whatever storage system you want to use to make a renewable perform like a baseload.

Solar is so much worse as it's $1.9 billion per GW for a pitiful 11% capacity factor here in Ireland.

No, the UAE did not use slave labour as the cost was higher than in Korea and what Poland has been offered and higher still compared to the earlier Shin-Hanul units 1&2 - so far they only look to be taking two due to trying to suck up to the US for geopolitical defence reasons, so will likely have to pay a bit more per unit.

Currently Czechia also looks to be after APR-1400s, as are the Netherlands. No one in their right mind is basing nuclear prices on the current financial disasters in the UK and France. They have lost their nuclear mojo, Korea hasn't and is on a roll.

If you have an open mind and truly want to find out what's the most expensive form of power generation, then I suggest you run the numbers on floating offshore wind. There are 3 main commercial scale projects; Hywind Scotland, Hywind Tampen and Kincardine OSWF. I could give you the numbers, but it's not Halloween yet.

The $24 billion price tag was in 2015 money, how much would that be post inflation for 9 years?

That price tag also represented a 20% coat overrun on the original estimate, did later quotes account for this or did they just magically wave it away to make it look cheaper?

cnocbui

https://www.boards.ie/discussion/comment/122120926#Comment_122120926

Did you miss the bit where the current Korean builds and the Polish offer price are lower? Even with that cost overrun, Barakah's final cost is still way cheaper than OSW in this region, it doesn't make a deal breaking amount of difference. OSW seems to need free finance, as many major projects have been cancelled due to cost increases.

Oh, and when doing that earlier cost comparrison, I forgot one of the vital considerations that doubles the difference in favour of nuclear, and that's plant longevity. OSW farms have a 30 year lifespan if you spend an additional 26-30% of the original capital cost on operations and maintainance, whereas these NPPs have a design life of 60 years.
