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.

The public lighting supply contract is currently with energia for supply purposes and they'd have to buy electricity for it etc so there is some metering. Replacing the bulbs with LED would leave most of the 2kW free. Charging at 1.7kW for 10 hours would get you 80-100km during your workday for instance.

But if an existing buried ductwork service is available then at least some upgrading can be performed without a major digging exercise.

If the likes of Tesco are willing to put in banks of DC chargers then Im all for that, I just cant see it happening based on the cost of it. Hopefully the cost does change.

Now that we've busted through the once a week charge covers the average weekly and a 50kW charger is 0.8C we can fill the gaps for on-street parking by 50kW district hubs instead AC chargers at every lamppost.

KCross wrote: » You don’t think we need that? We need AC and DC. Lots of. Has to be commercially viable though and being a small island the economics are a little harder.

Install 2 to 4 50kWh DC chargers and suddenly every Tesco carpark becomes a forecourt and a stream of revenue. they could add so many promotions onto it.. spend more than €50 in store, and your charge cost is free/reduced etc...

KCross wrote: » Charging hubs wont solve that problem. More AC solutions is whats needed for that. And even if it didnt have a negative effect on your battery would you really want to go to a charging hub and charge once or twice a week and sit in your car for 30-60mins or more. The public wont go for that... the charging hubs are for long distance driving, not for enabling those without a driveway.

If you exclusively charge on DC you can expect your battery not to last the course particularly the smaller batteries... until they change battery tech.
