I believe the ID.3 charges at 11kW on AC, so if the charger is an AC22 the ID.3 will be able to take 11kW from it.

most modern EV’s now can charge at 11kW.

older Tesla’s & Renault Zoe’s can take the full 22kW on AC.

the first batch of Toyota Bz4Xr3izžiïį’s that arrive here soon can only charge at 6.6kW though because Toyota are light years ahead of the competition with electrification of vehicles….

Thanks for that, would you need a different cable from the one supplied or would it's own do?

Just to add to this, you will need a 3 phase cable for this if I’m not mistaken?

I know I’ve had a 3 phase/22kw/32a cable from the start a few years now so not sure if you’ll get 11kw on the standard 16a cable.

Always be careful with this advice, a number of the ESB 50kW DC chargers are constrained by a site limit. By plugging into the AC and pulling 11kW you can reduce the available charge power for the DC car resulting in you both staying longer.

VW have provided a few types of cables so it depends on what you got. You’ll need to check the markings on the cable. It needs to be 3-phase to get the 11kW on that charge point.

Is it not just a 6 sq cable as opposed to a 2.5 sq cable rather than a 3ph vs a 1ph

No a 3 phase cable has additional wires to carry additional phases, what you are referring to is cable weight / area

Say I got a 3 phase cable would that still work and draw 7 kWh from my home chargepoint, PS I don't have an id3 unfortunately I took the cowards route and bought a phev, I'm just getting info for when I change to a full EV.

Depends.

If its a 3-phase 16A cable, no... it will just charge at 3.6kW at home (230V x 16A)= 3680W

This is because you have single phase at home so you only get 16A max to the car but on a 3 phase charge point you get 16A x 3 = 11kW.

If its a 3-phase 32A cable then you will get 7kW as your single phase at home will be able to pull the full 32A from one phase and hence get 7kW (230V x 32A)=7360W.

Just bear in mind you won't get 22kW from those public 22kW charge points as all cars are limited by their onboard chargers which are typically 7kW or 11kW. Some exceptions to it (some Tesla's, Zoe) but the vast majority go to 11kW max on AC regardless of cables.

You still want to get a 3-phase 32A cable though as that gives you max charge rate in all situations.

As mentioned it's complicated.

First you need a car say 11kW capable. You also need a ChargePoint 11kW or 22kW capable which some are not. Thirdly you need a 3 phase cable between car and charger.

For home use ideally you would use a different cable or tethered cable as single phase 7kW is lighter, and you can have other cable dry and ready to go in car at all times.

If you buy a max 11kW cable often at home it will only work at 3 or 4kW on a home 7kW charge point.

If you buy a max 22kW cable it will work at full 7kW at home but it's heavier and more expensive than 11kW and 7kW Max cables.

Some/most cars come with supplied cables. Sometimes manufacturers supply the wrong/cheaper/ non ideal cable by accident or deliberately to save a few quid.

The ideally public charging cable is extra long 5 metre or 8 metre length as sometimes the parking spaces next to the charger are blocked but you can park nearby and run a cable safely to the charger. This can be very useful and save you having to have a plan b and go elsewhere.

I did not realise that 3 phase had additional wires but of course it is obvious - Now they both use a Type 2 connector so I presume that when operating in a single phase only one of the connections is live ( and another neutral) and all the others are not used.

Buy a 3 phase 32a cable. It will stay with you forever and all future cars.

You will never need a new one unless it breaks.

You’ll get 7kw at home, 11kw or 22kw out and about in public chargers once your car can do it.

Absolutely no need to be buying 2 different cables IMO.

Just spotted this on VW Ireland website and I'm pretty sure the eUp never made an appearance like this before.

Could you even get the E-Up in Ireland? Pretty sure it was only available as an import

It's funny that they're dressing up a car from 2014 as new, especially considering its out of production in most other European countries

Maybe they've got some UK stock that never sold? Hard to believe considering its popularity

Personally I thought the E-Up was brilliant, exactly what you need from a no frills EV. The only problem was the price, €25k was pretty steep considering what you got

It'd probably be considered a bargain nowadays however 😜

Fingers crossed that VW pull the lead out with the smaller ID cars. Something Polo or Up sized with a 45kWh battery and 100kW charging would be a great city car that is also capable of long journeys

Even that size of battery is almost too big for a small car. Aren't Tesla talking of 500km WLTP from a 30kWh battery with their new super efficient small car? Probably only a rumor and not presently possible..

TitianGerm

How much was an Up new here in Ireland? Surely if they could get the eUp here around €20-22k they'd sell bucket loads?

Given most current EVs are getting in/around 12-18 kWh / 100km .. the above suggesting 6kW / 100km seems ambitious, even for Tesla!

Has any manufacturer dropped below 10kWh / 100km in the real world, as opposed to on twitter?

the_amazing_raisin

https://www.boards.ie/discussion/comment/119787977#Comment_119787977

Yeah we're still waiting on that $35k Model 3 😜

I'm not saying Tesla's new small car won't be super efficient but they've been known to be a tad optimistic with their WLTP range estimates

I think in that segment you'll be running up against concessions on the size of the vehicle. It's hard to make a super streamlined car the size of an E-Up and still have a usable boot. In any case if the car spends 90% of its life at 40km/h or less then aerodynamics doesn't have as big an effect as the general efficiency of the platform

Still, it's going to be very interesting to see where Tesla go with their budget platform. Personally I think there's certain expectations of a Tesla (big screen, autopilot) which don't work with a budget car. I'd say it's more likely they'll go with a hot hatch type of car

It was just a bit from a vid yesterday by Teslanews.

https://www.youtube.com/watch?v=sjHOoLfUvrI&t=3s

Agree, a bit farfetched and with current technology probably impossible.

unkel

https://www.boards.ie/discussion/comment/119788398#Comment_119788398

Agreed, I think it simply isn't possible. The most efficient EVs ever made like the Tesla Model 3 / Y and Hyundai Ioniq 28kWh do about 14kWh / 100km WLTP. Even with a car half the weight of a Model 3 (this is only possible on a EU road legal car if the body is carbon fibre and the battery has zero weight), you wouldn't halve the consumption.

Even 10kWh / 100km in the WLTP cycle would be a very ambitious target

6kWh / 100km in a small efficient EV in a hypermiling run? Yes sure. But not in a WLTP test.

AMKC

Anyone any idea what this car or make is that was seen testing in Dublin today?

Xpeng G9 I think.

Nio ES6 / ES7?

AndyBoBandy

Probably had to abandon it because they couldn’t find a DC charger!!!

unkel

https://www.boards.ie/discussion/comment/119789029#Comment_119789029

They did find one and plugged in but then a Leaf rocked up and their charge stopped when the Leaf owner plugged the CHAdeMO in 😂

the_amazing_raisin

https://www.boards.ie/discussion/comment/119788758#Comment_119788758

Maybe they'll make it a pedelec 😂

Wasn't there a Mercedes concept that got something like 10kWh/100km average? That's probably as close to state of the art as there is at the moment

I saw something recently about how the next generation of electric motors will be about half the weight of the current ones.

And I guess chassis integrated batteries would save some weight, as well as being cheaper to produce

Still... you'd need a step change in efficiency to cover that gap, and I don't see how it's possible, let alone on a car worth $25k

There's also the consideration of whether Tesla actually wants to make a cheap car. As I said, it doesn't really fit in with their current lineup

If they get costs down by 50% (which I actually think is possible, if some concessions are made to range) I'm not sure that'll translate into a 50% drop in price. Elon does like money after all, and he does have shareholders to impress
