depends on who often you need to travel from one side of the country to the other, if its a few times a year stopping to charge is hardly the end of the world given most modern evs require a 20-30 min fast charge to get you back to wherever you came from.

Sure its only 20 - 30 minutes, until its not, I was replying to amazing raisin, why would people spend 20 k on a government incentivised BEV that would only save them 1000 euro a year, when a Toyota corolla cost 27.5k or a Yaris costing 22k, a 20k BEV will not have great range nor will people have to worry about charging, changing a battery after 8 years, which is a commonly held belief or another one that makes me laugh is the huge electricity bill.

A short range EV would work, but would people accept that 20 to 30 minute stop for the sake of a very small amount of petrol a few times a year given that they would know next to nothing about an EV, I would think they would suck up any carbon tax increase and put their money in a safe conservative purchase. I think most would actually try a self charger at first rather than go BEV.

We are getting rid of the company Tesla, it doesn’t serve our purpose, we are partly responsible as we clearly didn’t do enough research. We will review again in a few years, I’m sure better batteries and charging network then. We will keep the PHEV as there is the reassurance of petrol when no chargers/ broken chargers or EV owners parked all day at chargers, some not even plugged in.

If selling privately, send on the ad. Myself and few others looking out for a second-hand Model 3, albeit value against new is currently not great.

More than likely be trading it in as it’s a company vehicle.

There'll be a nice balancing charge on that then on the CT1 for 2022 with the way trade in prices are and if you claimed accelerated capital allowances.

Okay I see your point, and yes you'll probably need to use a destination charger or do two fast charges. For the money we're talking about you'd be looking at something like an Opel Corsa E

Whether that is suitable or not depends on your definition of suitable. I think we're just going to have to agree to disagree on this one. I personally think that something like a Corsa E is fine for longer journeys if they're occasional.

If I were commuting Limerick to Dublin and back every day then I'd be inclined to spend more on a car anyway, after all I'll be spending 4-5 hours a day in it regardless of stops

I think one thing we could agree on is that if chargers become as ubiquitous as somewhere like Norway then living with a smaller battery EV becomes a lot easier

Imagine that same journey if there were 6 or more HPC hubs along the motorway each with a minimum of 4 chargers, plus a roadside indicator to show how many chargers were in use (a bit like how motorway services have signs with the fuel prices before the exit)

Personally I'd have no reservations about that journey in any EV if that was the case. And I think if there was a sudden flood of smaller battery EVs then the business case for charging hubs becomes a lot better

More charge point discussion in the IT. Seems to be some sort of smart system to manage load of DC across lots and lots of parking spots. I can't imagine how it would maintain high speed kW if the car park was busy. BUT if it was "everywhere" then you could be getting little and often as compensation.

It's just load balancing, nothing new.

I thought the same the whole time I was reading, but then in the article he explicitly says it isn't... ?

"“Essentially DockChain ‘tells’ each car it’s the charger and tells the charger that there’s a car ready to be charged and off it goes. We avoid the whole issue of load balancing electrics which is pricey,” Sheehy says."

It's load priority, which is just a different process of load management

Basically the cars plug into a queue and the system will either charger them in order they plugged in, or give each cars

It's an interesting process especially if they can hit the price point they're advertising

slave1

We need more software, the eCars high power units restricting EV A to 75kW when a Leaf hooks up to split the load and that car only take say 43kW is madness, a waste of 22kw.

Another example would be car a nearly charged so tapered to say 20kw by the car, then another EV hooks up and is losing 55kW.

Silly stuff

Pretty amazing achievement with an electric bus. Managed to do the whole trip on public charging with 300+km between stops

I think that's a hardware issue, the particular models eCars purchase have DC rectifiers in 75kW blocks. Other charger makers use different size blocks

Interesting and pretty decent it can do >500km in between charges. Charging on existing public chargers is a no-no though, takes far too long (3 hours according to the article). If a Tesla with a 75kWh battery pack can charge at 250kW, then a bus like above with say 4 times that battery size should be able to charge at a megawatt, perfectly doable if the battery voltage is over 1000V, for a charge time of maybe half an hour

Obviously you need to have a charger that can support those sort of figures 😁

Yeah I think they'd struggle to fit in the parking spaces at one of ESBs "hubs"

I suspect there'll be dedicated bus chargers at depots. The cost savings versus diesel should make it pay off pretty quickly

Some quick maths using the energy usage figures they provided in the article gives a saving of around €500 (assuming electricity at 30c/kWh)

That's roughly the same as going from Dublin to Cork 10 times, so they'd save €50 per journey. So how long does it take to pay for a charger?

I've heard the latest Ionity units can supply 450kW, so let's use that as an example

Going by the article they seem to have an average consumption of 1260Wh/km (ouch)

So a 560km journey from Dublin to Cork consumes 700kWh and would require 90 mins of charging using our 450kW charger

Journey time is about 2:30 hours so let's say 4 hours total per trip, gives 6 journeys a day if you kept the bus running round the clock

Let's take a more realistic 4 journeys a day and put a charger at either end to shorten the charging stops to a reasonable 45 mins. If the chargers cost €200,000 to install and you're saving €200 per day then they're paid off sheet 1000 days, or roughly 3 years

That seems like a fairly reasonable payback period all things considered, and that's assuming you only have 1 bus trundling bank and forth. If you had 3 buses, which it feasible given the journey times, then you pay for the chargers in 1 year

Shell in the U.K. with some epic greenwashing at a brand new petrol station, installing 2x Type 1 7kW chargers……

slave1

LOL, type 1, likely 3.3kW/h on Leaf's

the_amazing_raisin

https://www.boards.ie/discussion/comment/118697034#Comment_118697034

They probably got them for free out of some parts bin

unkel

You couldn't make it up. Now that I own a Fluence, I recognised the Type 1 immediately. Yeah, the car can do max 3.3kW on one of them. As can the original Leafs.

NIMAN

Surely they have to appeal to EVERY possible user who arrives at their forecourt?

If they had no type 1 at all, sure people would complain about that too.

More than likely just a place holder. Till proper units are installed.

AndyBoBandy

My guess is someone in charger of ordering, who didn’t have a clue…….

And when they were asked to tick the Type 1 or Type 2 box, simply played it safe and went for Type 1..

the_amazing_raisin

https://www.boards.ie/discussion/comment/118698704#Comment_118698704

Plus the fact that they call that a fast charger in the UK probably added to the confusion

the_amazing_raisin

https://www.boards.ie/discussion/comment/118698638#Comment_118698638

Not sure I'd be so optimistic, if they'd installed a decent power supply then they would probably put in 22kW units

Has anyone got there nissan leaf connected to there WIFI, so you can update software?

the_amazing_raisin

https://www.boards.ie/discussion/comment/118699034#Comment_118699034

It has a WiFi connection? I'm guessing it's a newer one than my old 2016 Leaf24?

It's a 2020, just wondering how to connect to house wifi..I know it has 3g telemetry with nissan (I think). ?

Leaf updates are over WiFi since inception. Only at dealers though

Thanks 👍
