MCB also protect from electrical shocks/fires as a result of short circuits or current overload. Sockets will also go through an RCD

I have not been killed yet is the phrase, or a visitor or child that pulls on plug with live wires. At least install a changeover switch next to fuseboard. Generators are handy in very rural areas where power may be off for a day after a storm and power may be needed for oil burner heating and lights, but risking ESB staff and visitors with total liability yourself is crazy. I have worked on mechanical and electrically isolated automatic changeover generator systems with auto start. These are great for automatically kicking in. Typically heavy loads are set up to trip off when power goes, so nearly everything in house works. If you experience power cuts regularly it's worth it for the convenience.

Geni is in a shed that's locked with no access to it except for me.nobody can get electrocuted.i haven't used it in about three years .I am very competant of what I am doing.i only mentioned it in passing .it's not something that is a regular occurance.

Missed this story from last week (apologies if already discussed).

There is still a lack of knowledge out there from dealers about EVs.

I was interested in an Ioniq on DD, but it had high mileage and I asked the dealership in an email if they knew what the SOH of the battery was.

The reply was, "the car is in fantastic condition, and the dash is showing a range of 200km".

Ioniq 28 have a massive "hidden" buffer, plenty of these cars are still reporting 100% SOH 5 years in, can't be right of course as there has to be degradation so must be related to buffer management in the car

May be true but I'm still wary of buying an EV with 150,000 on it already.

100%, each car will be different, this one looks in excellent nick with 100% SOH after 92k miles

How long do EVs last? Lets look at this 5 year old Hyundai Ioniq Electric at 92,000 miles - YouTube

Since the above thread is no discussion thread I brought it over here...

What I really like about that UCD lay out is that they put the charge points and spaces back to back. Its a much more efficient way to put in charge points than a bank of chargers along a back wall where only one line of spaces can access them. Each one of the charge points above can be accessed from 4+ spaces.

When putting a charge point into my workplace I made sure that the charge point went in where 6 spaces could reach the single charge point. Eventhough the charge point can only charge two at a time it means that you can have 4 more cars "lined up" ready to charge and no need to be playing musical chairs and getting people to move so you can get in, which is hard to do with people in meetings, out to lunch etc.

You simply park in one of the 6 spaces, first two to arrive get first dibs and then when their sessions finish you unplug them(we've agreed that) and plug yours in... no need to get people on the phone to move their car etc.

The above layout is the same. Clearly not as big a deal when you have 12 charge points to work with, but in time when EV's outnumber ICE the above layout will really benefit those users.

I disagree. I think eCars have it right. They obviously have expertise & experience with regard to installs & are, indeed, Ireland's leading player in the game. They've over a decade of experience installing charging infrastructure. The even operate internationally, with great success!

No, a single charger against a wall, in a dingy, dark compact car park, with extra short cables & two spaces for cars to charge (unless one is a Nissan or PHEV) - that's the real future!

Hub? Who needs hubs! AC is for losers anyway - eCars have abandoned that & they know best!

Happy New Year to all!

You almost had me until you said eCars have it right

HNY to all of ye, may ye home charge and stay within range and never have to rely on eCars in 2022, I had just the one eCars session in 2021 and it was an unmitigated disaster where previous user's session was never stopped and took ages to restart the unit via eCars, all the while other EV's queued up around me and had to wait a further age

This is very random, its a 9 minutes long "podcast" from the BBC series Witness History on the first modern electric car. Very interesting piece

The GOM is irrelevant. When I bought my second Ioniq it has 220km on the GOM (and 100k on the clock) and now it's at 175km on the gom. It's all dependant on prior driving.

There seems to be a general consensus that the buffer in the ioniq BMS allows it to get to 150-160k km or 5 years, with still showing 100% SOH. This is of course done by hiding additional capacity - given the battery is 28kWh net and I can still extract 28kWh from my 172 with 120k on the clock it's clear that something is going on to allow this.

slave1

It's now known for certain but I've seen estimates of a 31kWh pack for the Ioniq 28

Bit of a disaster for GM over in the US. In Q4 2021, they sold 26 EVs. 25 Bolts and 1 Hummer. Do they even make any others at this point? It's not a very appealing lineup.

They stopped making them in August while they sorted out their battery problems, and haven't restarted production yet. They were due to restart in November 2021, but then changed it to late January 2022. When they get restarted, sales will improve, but I think their brand has been hard hit by the publicity of recalling every EV they've sold.

At the moment, GM only have the Bolt and the Hummer EV. The Cadillac Lyric is due into showrooms this summer, and the Chevy Silverado is due out next year, but I don't think they have anything else announced.

I'll still never forgive them for murdering Saab. That could have been a cool EV brand.

That's a fact! Shame that the NEVS also failed. Luckily we got Tesla as a consolation prize, in a way it's a very SAAB like company.

AndyBoBandy

Worth posting here too for the wider community, but the Tesla Semi Superchargers are looking like being 1.5MW capable….

I wonder will future hubs be where power lines meet motorways or next to substations with excess power? Grid connections for those sorts of chargers or multiple shared would be insane money be relatively less next to a substation. I could see truck stops popping up in strange places where grid connections are cheap.

AndyBoBandy

https://www.boards.ie/discussion/comment/118444802#Comment_118444802

I think Tesla are going to install these mega chargers with mega packs (batteries) beside them, so power coming from the grid would only need to be standard connection, and just be supplemented by the batteries, then when there’s no trucks charging, the batteries are filling up again from the grid.

ELM327

I think those megachargers are going to be at bases of companies who have bought semi(s). Unlikely we'll see many in the wild for some time. Very few truck drivers will want or accept a 30 min stop in the middle of a paid route.

UID0

A 30 minute stop is fine. Drivers have to take 45 mins break after 4.5 hours driving anyway. The issue they will have is if they have to wait for a charger to become free. That 45 minute break will become more than an hour, and that will cause them problems.
