7kW charger for a 62kWh leaf.
Leaf charges at 6.6kW gross, so lets say 6kWh per hour actually delivered to the battery. That would be approx 11-12 hours from absolutely empty to full, excluding any top balancing time. 15 hours if you're going from dead empty to top full doesnt seem unrealistic but I'd question the amount of balancing. Are you sure it's not a derated charger like 5kW or something? Or perhaps your voltage is low? It's actually a 32A charger and the voltage determines the kW. 32A at 209V is very different from 32A at 257V
I have a 7kwh charger at home for nissan leaf at 62v.
Help me with the math. It takes over 15 hours to go from empty to full. Am I not getting 7kw every hour and if so shouldn't it take less than 10 hours?
Assuming you want to park and ride and therefore go somewhere for a minimum of 3 and a max of 12 hours, 7kW for3 hours gives 21kWh gross so yes I agree with you. 11kW would be nice to have too, once it's not one of those badly implemented 11kW installs that only give 3.7kW on each side on single phase - ie 16A one or three phase
don't know where to post it so trowing it here. I have noticed this week that elli gives access to blink managed chargers. Q-park seem to have them here in Dublin, they claim 30ish chargers. I've tested the RFID card at Setanta last night and it worked like a charm and 11kW no less. Before, with blink app it was pretty bad due to coverage in underground carparks and 80 quid pre-auth per session. To bad my contract comes to an end in a few weeks.
I'd hope they are all a mix of 7-11-22kW AC chargers and priced accordingly (ie 7kW is cheapest and 22kW is most expensive)
7kW is the max you’d ever need at a park and ride facility…
Since it's a park and ride, slower AC chargers might be more useful. Or probably a mix would be good, lots of AC chargers plus a few HPCs for people doing a top up before heading home
I think this is the largest proposed EV charging facility in Ireland, at least that I have seen. Decision due tomorrow.
The development of a strategic Park & Ride facility located to the west of M11 Junction 6 at Fassaroe in the townlands of Fassaroe. The proposed development comprises a car park with a capacity of 388 parking spaces, including 26 spaces for mobility impaired users and 42 spaces for charging of electric vehicles. ....
Probably due to building regs.
these are the green units?
also had the same problem with the newer 50kw ones, just never goes above 45.
Some of the earliest DBT units only gave 43kW on DC due to incoming voltage and or outgoing amperage limitations.
I think on the older Ecars chargers there was a power meter in a fusebox near the bottom which let you read the power delivered from the charger
I have a vague memory there was some complaints about a few chargers in lower voltage areas, so they weren't delivering as much power as advertised
So many considerations.
Temp Of battery.
temp of weather.
state of charge.
state of health of the actual charge point.
not sure what existing thread this would go into..
have a leaf 2020.
but on the occasion i'm doing a fast charge, why can i always get 46/47 from a 50 hubs that is ran by easygo/plugsurfing (recently used charges in shannon)
but yet with ESB i don't think i ever got any higher than 45..... SOC is normally between 20-30 when i fast charge.
whats the units types they all use?
Except they don’t work in our cities. They tried bendy busses. But out road network was found unsuitable.
to many bends and corners
there was a blue line proposal around 2010 that woukd have served UCD and used the type systeM above

Ah so it's the old trick of referring to the human as an automation system 😉
DB have ordered 120 of them. At €800k each. But with the current cost of petrol they think it will pay off.
Chargers are being installed in depots as a matter of urgency. They are waiting on some Hitachi charging system.
Drivers are currently going through training for them. They have been testing them with onboard ballast to simulate real world conditions. They expect about 280-300km range. Normally a bus leaves the depot that morning with a full tank and drivers swap out at a specific bus stop leaving the bus on the road and in operation.
These may have to go back to the depot for charging mid shift or they may just use them in the city to reduce city emissions.
Lower passenger numbers also and no luggage storage so that rules out the airport routes.
That's easy, the driver (all the current examples have one) steers the bus back to it's planned route.
What happens when some a$$holes paint over the lines? Or paint new lines going down a different street?
Training involves maintaining passenger numbers as the numbers are reduced. Also what to do in an emergency situation.
Normally buses go out for the day and drivers are swapped at selected bus stops throughout the city so they don’t go back to the depot during the day as such.
The hybrid buses are rolled out on my local routes, so noise isn't too much concern as they rarely get up to speed due to junctions, speed bumps, roundabouts etc.
It'll be a long, long time before all the secondhand diesels are off the roads unfortunately. People like their secondhand diesel Audis and the like...
I don't think there is anyway we could deliver BRT infrastructure quickly in this city, if your going to spend that much effort you may as well install the tracks as it makes it much easier to stop encroachment on the busway.
If our political masters were serious about revolutionising public transport, they should take it one step further and simply copy what they are doing else where in the world...especially China.
Their Autonomous Rapid Transit (ART) is a battery powered track-less tram system that utilises self driving technology. No need for expensive tram tacks, just upgrade the existing road infrastructure. A mass rollout of this system could be achieved within a few years instead of decades, improve pedestrian access not only into the city, but around it also, whilst reducing congestion at the same time.
From a pedestrian perspective, I'm really looking forward to the electrification of the DB fleet. It's going to have a much bigger impact on life in Dublin than electrification of private cars. Unlike a car, most of the bus noise comes from the diesel engine, rather than tyre noise. Especially so when starting off from stopped which is quite frequent for a bus.
Huge capital expenses in the rollout, so I expect it to be slow. But I'll ask later if I get a chance
Someone on Reddit claiming to be in the know, but if course that means nothing. Was just curious if anyone heard they were being rolled out onto normal routes or not. I can't imagine any routes are huge mileage.
In fairness DB are or were having a lot of issues with the install of DC fast chargers for them, due to planning.
Exactly, I'm sure they've done their research before buying them.
Where did you hear that? I've heard from the horse's mouth that all but only a couple of DB routes could use these buses without having to charge them during the working day. All now charge at the depot, only after hours. They can CCS DC fast charge at 150kW and they have 350kWh available battery.
Average Dublin Bus does 250km per day, so that can easily be done on a single charge
Sorry but I can't listen to him say what the heck over and over😡
They're the EV version of the Siac van, a heap of junk like most modern vans. A neighbour has a 191 Siac and it looks like it's 30 years old already, horrible yokes, there's some racket out of the engine.
