I wouldn't worry about it mate. 7 kW is more than adequate. Even those that have bigger battery packs find it fine, Teslas for example.
You'll still be able to rapid charge and use any post out there.
In the real world you generally only AC charge at home or staying overnight somewhere as it's more hassle than it's worth on shorter trips.
You'll have to come back and tell us what you think of it. I really like the looks of it and may be a replacement for or Zoe in the future

 

As above I wouldn't be bothered. Whilst the 11kW onboard AC would be nice, it wouldn't actually impact me much on a day to day basis.

Remember the 11kW rate is the maximum peak rate. The battery temperature and the state of charge of the battery will dictate how much charge the car will actually draw. If you do happen to charge at a AC post that charges higher than 7kW, the real world difference isn't likely to be large, as the 2.5hr saving quoted is based on low state of charge, and optimal battery temp. In reality, the battery is likely to be colder and your likely to charge from a higher state of charge, so the difference will be much less.

You will still be able to use those higher rates AC posts, and it won't affect your DC charging rates.

 

Also, interested to hear your thoughts! I was quite surprised at the level of discounts on it for private purchasers, so hope they enter the used market in a couple of years at a good price!

 

Thanks very much for the quick replies, I feel much better about responding to the fleet company now.
and I'll let you know how I get on with the E-Corsa when it arrives, hopefully in May 2020.

 

Seriously considering ordering one myself!

 

Do you get a useful drop in price for accepting the 7kW version ? If not, surely this is a bait and switch ?

 

They originally said 11kW 3-phase because that's apparently common in German houses to power saunas etc.
Very few here have domestic 3-phase power, and I think it's actually on the options list instead of standard equipment anyway.

 

Do we know what the 11 kW charger can charge at if connected to a single phase UK 7 kW EVSE? I rather suspect it might only run at 3.6 kW if that 11 kW is actually 3x3.6 kW modules with one-per-phase for EU use. Would need some extra smarts in there to detecxt there's only a single phase coming in, so please reconnect a 2nd module in parallel to the first to increase it to 7 kW.

If it's a simple item & can only use 1/3 of the hardware when on single phase supply, then the 11 kW one is surely not a lot of use here in UK, as you'ld be Rapid charging on long trips anyway.

 

Do we know what the 11 kW charger can charge at if connected to a single phase UK 7 kW EVSE?

Based on ~7hrs to charge (from brochure) we can deduce it will use 7kW.

I expect the 3x16A unit is a volume item bought in by many OEMs and it designed to switch the modules as necessary. It may even be a worldwide unit with 48A capability for USA market.

Perhaps demand for that unit is exceeding supply and they are sourcing single phase 32A units for RHD cars. Or perhaps a cost saving approach.

 

I suspect 7 KW is usally just 6.6KW rounded up its not too disimmilar to the rounding up and down that everyone used to do with enigne cc sizes

 

240v x 32 amps = 7.68kW
230v x 32 amps = 7.36kW

Perfectly possible to achieve if your charge point and car both support 32 amps. Some 7kW charge points are limited to 30 amps however:

240v x 30 amps = 7.2kW
230v x 30 amps = 6.9kW

The 6.6kW figure will relate to the limitation of a specific model of car, not of the Type 2 charging system, as naturally not all cars will draw a full 32 amps or even 30, and will err on the side of being conservative.

 

I've had another look at the configurator page. It now offers a choice of 7kW or 11kW AC charger.

 

If you go for 11kW just be sure that it can still do 7kW on single phase as it's likely, but not guaranteed depending on the design of the charger.

 

Smart EV (first gen.) - 1.0 or 0.99, can't remember exactly, measured by a cheap plug-in meter.

 

Hi everyone,

first post here and came across this when looking for an answer as to the 7.4 kW vs 11 kW as I too am looking at an electric Corsa. Obviously there is a cost benefit as well as a delivery benefit to going with the 7.4 kW charger but im wondering if you went for the 7.4 kW and then found out you really wish you'd gone for the bigger charger, can you just buy the bigger charger or is this something that is physically hard wired in to the car and cant be easily changed?

Cheers,

Tom

 

No unfortunately it cannot be changed.

I would check around your area and see how many type 2 11kW or 22kW chargers you have to see how useful it would be.

Even if you did, having a 11kW peak charging rate over a 7kW peak charging rate is unlikely to make a massive real world difference to charging times.

 

The 11kW, 3 phase option is more relevant to much of the continent, where many houses have lower current, 3 phase connections, rather than the higher (typically 100A) single phase connections used in the UK. I think they can be limited to about 4kW on a single phase(?) in which case the upgrade to 11kW, 3 phase is far more significant.

 

Thought this might help

 

 

I’ve gone for the e208, which is the same car under the skin, and I didn’t opt for the 11kW option. I really can’t foresee a time where I’d need to charge from low enough to high enough to benefit from the time saving, whilst also not having the time to just leave the car there a bit longer. It didn’t seem like it made a lot of sense to me. I could only really imagine it being useful if you were a 2+ EV household and needed to cycle cars on charge. Maybe there’s an upside I’m not considering, but it seemed like just an option to offer for the sake of charging a little more money to me.

 

11kW charging only works at home if you have a 3 phase supply, which is rare in UK homes at present (it may change as we move from GCH) Some people have installed if they need to charge quicker, but it can be expensive. Also most 3 phase charging points are expensive - the exception is the Tesla one, but IIRC only Tesla owners can buy it and no OLEV grant.

There are an increasing number of 22kW public charging points, but I agree the extra cost of 11kW on the eCorsa is probably not worth it for most UK buyers. The included 22kWh capability on the Zoe is very useful in this regard, but they charge extra for CCS DC!

 

I have an E-Corsa on order as a Company Car due for delivery in May 2020.
I have had a email from the fleet company saying:

Further to your recent order for the Vauxhall Corsa-e, the dealership have advised us that at the time the order was quoted the only available vehicle was the Corsa-e with the 11kw charger. However since this time they have received this communication from the manufacturer which advises there will be significant delays on vehicles ordered with the 11kw charger.
No estimated delivery dates have been advised yet.
Due to this the default position is that vehicles will be ordered with a 7.4 kw charger.
Could you please confirm as soon as possible whether or not this will be acceptable to you? If you do wish to proceed with the 11kw charger they must place the order with the factory no later than Friday 06/12/19 to ensure the original price is honoured; a price increase is due from 06/12/19 and they have not yet been advised what the new list price for the charger will be.

I was only expecting to have a 7.4 kw charger at home anyway (as I don't have a 3 phase supply), so is this really an issue for me.
What are the downsides? I will still be able to DC rapid charge at the Motorway Services?
I work on some site where I can plug in whilst I'm working before the long journey home, if these are 11kW will I not be able to charge at all or just at the slower rate?
Sorry for all the questions, I'm a total noob.
Thanks in advance
Christian

The 11kW would be 3kW on your UK home charger, assuming it is a 3-ph 'continental' rating.

You will charge twice as quick at home with 7kW than with 11kW.

(Ah! the modern challenges of being tech-aware!!)

 

UK Is 2 phase so would be 7kw as most other cars. Sounds to me like unless you have 3 phase your still only at 7kw for home charging. 11kw is still not fast enough for long journeys so I really don’t see how that’s going to be worth getting.

 

Bear in mind that not all LHD European countries have domestic 3 phase and in some countries it even varies between regions of the country. We know from the brochure timings that an e-208/Corsa-e with the 11kW option will charge at 7kW on single phase.

The current i3, Mini, e-tron SUV, Taycan, Polestar 2, ID3, e-208/Corsa-e (and probably others) have 11kW charging 3 phase and 7kW single phase. The solution is now well established in European cars and they probably all buy in the same OBC unit (it will be a single unit with solid state phase switching).

The B250e is the only 11kW car I am aware of that doesn't support 7kW single phase. It was designed a long time ago and is no longer sold.

Podpoint have a useful section showing what cars are capable of on single and three phase (click on car to see).

You will take twice as long to charge at a 22kw AC charger , compared to a ZOE, but if that is not an issue, then no major biggie.
for me , the 22kw is key, as there are few rapid chargers where i live.

 

Is very simple... If u use the car for longer trip than 150 miles will be hard for u to chage only with AC... And when you will neded after a long trip will be empty... If the car has the half price maybe.... but better no! Try another dealer or other car.... peugeot e205 is very similar, or Zoe.... Now there are good prices on e-golf (the end of making...)
