Random EV thoughts.....

Someone call John Hinde.

Shame they don't know the difference between V and W...

My main idea wasn't HVDC charging: the use of a coupler pretty much means it'll be AC only anyway, as for safety reasons, DC charging can only be done on uninterrupted cables, and DC charging cables are also a very expensive thing to be providing at every station. The big advantage I see is in the cold-plugging, and making mechanical connection as needed. Don’t forget the cost of electrical cabling when you’re working out how much even a 7 kW charger per parking bay would cost: the bigger the car-park, the more expensive this gets.

The specific example I was thinking of was airport parking. Here, you’ve a thousand or more cars, parked up for at least three or four days, maybe two to three weeks. As you get more EVs on the road, more people would like to have their EVs charged up while they're away on holiday, thus avoiding the need to re-charge on their way home, perhaps. The only way you could offer this service at a reasonable price is by cold-plugging every bay, and then have a robot/dude hook up the cars as needed until they're charged. A computerised booking system would make it easy to figure out where and when each car gets serviced, and the advantage is that you can use mutliple high-power AC charging (22kW) feeds. Ten or twenty such chargers could be used to electrify hundreds of parking spaces.

The same principle applies in a different way to daily park+ride: very few commuters need their car fully recharged to 100% in order to be able to go home (you wouldn’t buy a car with just 200 km range if your commute to work was 180 km!) - drivers who do need a charge top-up may only need 5-10 kWh; but despite only needing the 22kW charger for 30 minutes or so, they actually prevent anyone else getting a charge for the whole day. Being able to attach and detach the same charger to different vehicles is a big advantage, regardless of the charger’s rating.

Or, far more simply - provide 3kW charging at each bay .. Enough for a day-trip replenishment for many cars, and easily enough to charge even the hungriest of the current bunch of EVs over the span of a few days ... heck, 2kW per bay would be plenty in airport carparks unless it's the short-term carpark.

I get what you're saying, but I feel like cabling every spot would be fairly cheap compared to some sort of hot plug system. Reliable mobile robotic systems aren't cheap after all

You could still have a load balancing system which queues the cars, it would just be software controlled instead of a physical robot moving around

For something long term like Dublin Airport, you don't even need 7kW, 2-3kW is probably enough for most people staying a few days

I mean, if nothing else you'd have to tarmac the Blue car park in Dublin Airport for it to work 😁

The solution already existed at quickpark (now closed) where you booked a premium parking space and left charging card on seat. Car would be recharged near return date and moved to express collection point.

There is big money to be made and at Dublin airport many airport own vehicles including plane movers are 100% electric.

Start off with 20 premium spots and increase based on demand. Already the ferries charge a premium to book the EV charger.

I do agree the financials for profit making on AC chargers do look problematic if you are not billing crazy prices or not getting other income such as hotels a few of which still offer free charging.

I heard a comment from easygo that in street AC chargers all need a separate esb supply and esb meter which makes them crazy expensive as esb networks are the only ones who can run power lines under public footpaths. The monthly meter cost alone would make these unviable in scale particularly if chargepoint is not in daily use.

Same old nissan

Abject crap that can't cool/heat itself and cant use CCS

LOL, you never know. If you had told me today 6 years ago that I was about to buy a Hyundai. A brand new one at that. I would have laughed. Or that I would ever own a Tesla. I have just ordered my 3rd one.

80kw DC max charging....for a 90kWh battery!!

Maxus are imported via a distributer (Harris Group). Personally I'd never buy a car that doesnt have direct manufacturer support in the country as warranty claims can get messy, especially if the distributer decides to cease importing vehicles or has their import licence revoked.

Still I think we are finally going to see more of the Chinese brands making inroads here.

Same tow rating as a Model Y, i4, EV6 is a bit disappointing

Id3 would do me nicely 😎

Just don't like the look of them tbh. I'm up to my eyes in a crappy PCP deal atm I need to get very close to the settlement figure (sept 24) and make a decision then.
