The key elements include six high speed charging hubs on motorways capable of charging eight vehicles simultaneously; 16 high speed charging hubs capable of charging four vehicles simultaneously; additional high power chargers at 34 current 50 kW locations; upgrading over 50 22 kW chargers to 50 kW, and replacing up to 264 locations with 528 charge points at the pre-existing pilot grade of 22 kW to next generation high reliability models.

I wouldn't be surprised if it's the ESB Networks division that's encouraging so many dual AC installs. At least they seem to treat eCars just as badly.

Especially in Norway where it's not uncommon to see some 50kW-150kW from Fortum/gronn kontakt, colocated with 4-6 Ionity HPCs and a supercharger site to boot.

Automatic dynamic charging. The dynamic power-split function of the Ultra Fast Charger will provide all available power (up to 150 kW) to the first car that charges. As soon as additional electric vehicles are plugged in, the power of the charger is automatically and dynamically split among all the charging vehicles. Some versions of the Ultra Fast Charger can even serve up to six electric cars, while charging up to four in parallel.

The customer bears the cost of these changes which could involve laying extra cable or more overhead wires, along with more transformers and other equipment. So it can get pretty expensive So yes, it's not exactly easy, but they're not exactly proceeding with breakneck speed. It's been several year and there's no sign of additional infrastructure going in for more chargers. And remember, this is the same ESB that said the grid can easily handle 1 million EVs

An EV taxi driver would probably definitely see it this way.

The dirver told me that the car gives him about 250km and he rarely drives more than 200km so is happy to charge at home overnight. I would say that City taxis are probably not going to want to use fast chargers. Those making out of county trips from Heuston might.

McGiver wrote: » I believe the new "replacement" chargers are now 50 kW DC and 22 kW AC, I've taken snaps of that in Galway, there was a sticker with the ratings there. Not sure how the AC/DC load balancing works though. Saying that - why would there be a fast charger on a railway station??? Railway stations should have banks of 3/7 kW AC not a single DC! What's the point of a single DC there? I see ECars are good at planning and futureproofing.
