I think people would be happy if they could do 600 km in all types of weather and not have 5 apps to charge, cost the same, be sure the battery won't have to be replaced like a Tesla MS or degrade like the leaf.

There is security in knowing you don't have to bring an extension cable and stick it in through a petrol station window to get home.

Having a look last night at what the NSW State Govt in Australia is proposing as part of their EV charging strategy. It clearly sets out how the retail side of things should devlop (along with funding incentives). This then feeds into planning for power availability and access by the wholesalers

https://www.energysaver.nsw.gov.au/reducing-emissions-nsw/electric-vehicles/electric-vehicle-fast-charging-master-plan

They have a stated aim "which will co-fund charge point operators to install and operate ultra-fast charging stations at 100 km intervals across the state, and every 5 km in metropolitan areas."

No mean feat given the size of the greater Sydney metropolitan area is 12,367 km2. In comparison County Dublin is 922km2.

Wont be without challenges, but at least it gives a very clear signal to industry and consumers alike.

From the FAQ:

How should the requirement for 2 x 350 kW bays and 2 x 175 kW bays be interpreted?

We are looking to provide a world class ultra-fast charging network, future-proofed for an increase in EVs, improvements in charging capabilities and caters to vehicle technology not currently available. 

That is why funding is being made available through these grants to ensure a 500 kVA minimum connection threshold, allowing for financial assistance to upgrade the grid where network augmentation is required. The 500kVA connection can come solely from the grid or from the grid and other energy generation/storage options on site (see eligible expenditure on page 56 of the funding guidelines).

Each charging station within a bid requires a minimum of 2 chargers that service 4 bays, with a minimum of 2 of those bays being able to charge an EV at a theoretical peak speed of 350 kW (+/-15%) and remaining 2 bays at theoretical peak speeds of 175 kW (+/-20%), and all stations must also include slow charging redundancy options. Theoretical peak speed means that the single charging unit must be able to charge one vehicle at that speed, or 2 vehicles at half the theoretical peak speed simultaneously. 

So long as these minimum requirements are met we will accept capacity combinations, such as: 

- Two 350 kW charging units that service 2 bays each (able to charge vehicles at two bays at theoretical peak speaks of 350 kW (+/- 20%) or 2 vehicles at 175 kW simultaneously). 

- Two 350 kW charging units that service one bay each, with one 175 kW charging unit servicing the other 2 bays (able to charge one vehicle per bay at a theoretical peak speed of 175kW (+/- 20%), or 2 vehicles at 87.5kW simultaneously).

- Two 350 kW charging units and two 175 kW chargers, with each charger servicing one bay.

...

To be eligible your project must meet the following minimum requirements: 

- a minimum of 2 chargers to service a minimum of 4 bays concurrently (i.e. 4 charging plugs) 

- a minimum of 2 charging bays rated at a minimum of 175 kW per bay (+/- 20%) 

- a minimum of 2 charging bays rated at a minimum of 350 kW per bay (+/-15%)

- includes redundancy in the system (e.g. an additional 22 kW AC plug) 

- has a minimum connection of 500 kVA to site (where applicable) 

- evidence where a proposed station connection capacity of 500 kVA is not possible (including evidence for rationale behind reduced connection size), and the proposed new total site connection capacity.

There's a weird choice of metrics though. The % of high speed charging stations is the percentage of AC charging stations that are "high-speed" (undefined actual speed, though)

innrain

https://www.boards.ie/discussion/comment/119293674#Comment_119293674

AC is never high speed. AC is just a socket. As long as it charges flat up to nearly 100% it means slow charging.

It's a bit of a weird statistic alright. I assume it's based on the theory that most public charging would be AC charging

I guess it makes sense to some degree, for example if I was driving Dublin to Cork, and there was an abundance of AC chargers available in Cork I'd probably just do the minimum DC charging needed to get there and get the majority of my kWh from AC

liamog

The index seems a little bit whack in my opinion. If you follow the source data https://alternative-fuels-observatory.ec.europa.eu/transport-mode/road they seem to have picked a metric where low numbers of chargers plus low numbers of BEVs score quite high and for some reason a high number of FastAC connectors is a classed as a high number of high speed chargers. They even call out Estonia for being forward thinking with FastAC whereas the reality is it's a dead end and should be removed.

Interesting….. 90 new ‘Rapid’ chargers at sporting facilities…

I'm not sure sports facilities are the best place for rapid chargers. Rapid chargers should ideally go in either en-route locations (e.g. motorway services) or in places where people will naturally spend an appropriate (approx. up to 1 hour) amount of time, but where individuals don't generally arrive and depart at the same time. Sports facilities don't, in general fall into the first category, although there are some exceptions such as Tinryland GAA in Carlow (which has a Circle K on the other side of the motorway where there is a new charge point being installed). They don't really fall into the second category either as people will generally arrive either for training or a match, and will be there at approximately the same time and for approx 1 1/2 hours to 3 hours. Given the general public won't be sure what times matches or training are scheduled, they are unlikely to plan to stop there, as there could be a car just after plugging in that won't move for 3 hours, and it is likely that there won't be facilities around the area.

A more appropriate location for rapid chargers is supermarkets or, if you want sports facilities, gyms. They tend to have a more evenly distributed arrival time of patrons, and would have lower levels of overstay.

The amount allocated seems quite high as well (nearly €170k per unit), unless they are installing in remote facilities that need major grid connection work, or they are >=150kw chargers.

liamog

Yes I would of thought a deployment of multiple 11kW chargers was much more suitable for sports facilities. Instead of deploying 1 150kW DC connection they should supply 14 11kW AC units and probably save substantially on the costs.

AC chargers for workplaces, hotels and train stations. DC everywhere else for en route top ups and for those without home charging capabilities

I believe Iceland is very far ahead in terms of using EVs to get around. However it has a tiny population mostly based and working in the one place. It shows very bad on the chart but is good in reality. That said as a tourist in wilderness areas there would not be charging in off the main road.

I generally like well made country by country EV comparison, particularly in UK terms usually shows up NI as terrible compared to even Wales and Scotland shines above the rest of UK. Most of these statistics often do t take into account typically 20% of chargers don't work at any one time in general, particularly where they are old and out of warranty. A lot of chargers in NI are broken.

This needs to be read in conjunction with the two recent documents from the LAs. Especially the strategy document published by the Dublin LAs. I'd say the sport grounds proposed are owned or controlled by the LAs and the type recommendation is tilted towards DC charging. When installing a public charge point it seems civil works costs are the highest costs so by installing DC you kinda optimize. In one case study, LGMA shows that installing an AC charger costed as high as 30k! The sport facilities are the low hanging fruit for the LAs and ultimately state as we can see that land ownership is a hard pill for ecars. The 15M for 70 chargers is high but these are press releases and we know how they operate. 10M brochures and photo-ops and the remainder goes to the project

slave1

There is something wrong if an AC charge point is as high as €30k, these are what we are all doing at home for a fraction of that. I had this exact same conversation in work a few weeks back with head of Maintenance, an EE requesting a charge point install for their EV and the quote was thousands. I told them an outside socket is fine which we could install ourselves for just cable/socket cost, ER are not here to charge EE cars but no problem with a modest top up, in work for 8.5hrs a day times 2.2kW is a respectable ~17kWh free charge. EE said no and that's it, no charge points in work if that's the attitude!

30k ex VAT. the end result

Well as much as we want the public infrastructure improved that is something that should never have been done from a financial perspective, as an FC in the private sector there is no way that would be approved

Why are they installing 22kW chargers? If they had gone for 7kW, I presume the hardware would have been cheaper and the need to move to 3ph would have been removed?

I suspect there’s a lot of people in LAs at the minute being told that EV charging is now part of their job but they don’t know a lot about it so they’re copying eCars or doing what the suppliers tell them to.

Those 200kW units with 2-4 plugs are ideal for this scenario. If you're lucky you get 200kW, worst case scenario you get 50kW

11kW for a 2 hour stop is 14-22kWh for most cars. Not really worth the hassle

mfceiling

Charged today in Portrush Co.Antrim.

Someone had stuck a laminated sign on the charger with "6 new chargers now available at Kelly's caravan park" printed on the poster. Can't see any info about it online so maybe it's a new thing?

Also noticed the car takes 12kw from the 22kw AC chargers. I thought it only ever took 11.

In NI the voltage is slightly higher so you’ll get 12kW…… voltage would be closer to 250 up there compared to 230-240 down south.

Looking on Google maps there's a "chargepoint charging station" marked at Kelly's

Yeah there's 6 22kw stations on the app.

Good to know, it's on plugshare anyway. £6 overstay if plugged in and not charging after 20 mins.

Another new charging provider as well, stopntop.ie. They don't show the price for charging at any of their stations unless you register.
