Hi All,

I've just placed my order and am currently waiting on a delivery date. I want to get everything sorted out well in advance of the delivery so I'm in the process of getting quotes for a home EV charger. I've heard that the charge cable supplied with the PS2 won't charge at 7kWs from a home charger in the UK - is that correct?
If so what are you all doing to address that? Tethered home charger? Buy a replacement cable that will charge at a higher rate? Accept the low charge rate? Something else?

Apologies it this has been answered 100 times before but as you may have gathered this will be my first venture into an EV.

Ta,

Scott.

Generally a tethered charger is more convenient anyway for home use. You don't want to have to get your cable out of the car every single time you park up, then put that same cable back in the car dripping wet / covered in snow / mud / whatever else...

Unless there's an overwhelming reason not to, I'd go tethered.

A tethered eg PodPoint charger costs about 30 quid more than the equivalent untethered, and for most people is more convenient as it’s just there and you pick it up and plug your car in with no fuss. Equivalent cables cost about £150, so that’s good value and the only drawback is it can’t be removed.

Personally I’m not planning to buy a 32A cable because I have no intention to charge at AC chargers away from home.

If you think you might do this (eg at work), then by all means buy a cable, many are around the £150 price point, but I still think tethered at home makes sense and you can just leave the 32A cable in the car and not have to remove it every time.

And yes, inexplicably, the cable supplied with the car will only charge at 16A (3.6kW) on a single phase supply.

Thanks for the replies (y). The main issue my Mrs has is around how it will look. The way my house is means that the charge box will have to be in quite a prominent position at the front of the house and I think I'll have a harder sell with a tethered charger as, from a quick google search, they don't look quite so tidy. Do the tethered cables all have to be manually wrapped round the box or is there such a thing as a retractable cable version?

If you want a pretty tethered charger where the cable is not visible...

(click on Gallery)

... but a little pricey! Available in about a dozen different finishes. From £1045 installed (after deducting grant).

Pod Point has a decent design where the cable wraps round the outside, although it's still a fairly bulky unit.

3567


Really though, these things are going to be commonplace in a matter of years... probably not worth worrying about.

Yeah, you guys obviously have a very different opinion to my wife as to what looks cool at the front of the house. It took quite a bit of persuasion to get her to go for an EV. I suspect a cable strewn across the drive / hung on the wall might be a step too far. Sounds like the options are to buy a separate 1 phase cable or stump up more for a "designer" tethered charger that can hide the cable.

I called Polestar who definitely confirmed that the supplied cable is only 20 amps and will therefore only charge at 3.5kws from a home 7kw charger. After spending £50k on a car their best advice is to "buy a 3rd party 32amp cable" - genius. This is really disappointing.
Can someone please confirm how the supplied cable charges from a public 22kws charger. Will it still only draw a 3.5kw charge?

From a three phase charger (11kW or 22kW) with the supplied cable, it will draw 11kW.

From a single phase charger (whether it be 3.6kW or 7.2kW) with the supplied cable it will only draw 3.6kW.

Your choices are...

a) buy a single phase 32A cable but that then means carrying two cables around with you (three if you include the granny charger).

b) buy a three phase 32A cable which is then universal and will work anywhere. You would no-longer need to carry the Polestar supplied cable.

c) consider how often you will actually be using 7.2kW chargers and forget about it

Bear in mind none of this affects DC chargers which are always tethered.

The best cable to buy is the BP Chargemaster one. It's really nice quality cable and uses genuine Mennekes connectors (the people who designed the actual connector).

Hi Steve, Thanks for the detailed reply. I think I followed most of what you are saying above (but I'm not electrician) so please bear with me.

If I buy a single phase why would I also need to also carry the PS supplied cable? - Is it because a single phase cable won't work well with a public AC 11/22kw charger?
A separate 3 phase 32amp cable sounds like it would cover all bases and get the max charge rate from either a 7kw home charger or any AC public charger - I'm guessing they cost more, I'll check out BP Chargemaster (thanks for the recommendation)

TBH honest with this being my first EV I have no real feel as to what my charging pattern will be - initial thoughts are to use the home 7kw charger every couple of nights to keep it topped up.

It has really annoyed me that PS don't make this point more obvious. They have it front and centre that they can charge at up to 150kws but don't really make it clear that the supplied cable is pretty rubbish for home charging. Out of curiosity what's the charge rate you get from using the granny charger?

Buying a single phase cable is a bit of a faff as it would then mean you'd need to know exactly what kind of charger you were connecting to as well as carrying both cables.

If you were connecting to a three phase charger (11 / 22kW) then you'd need to use the Polestar cable.
If you were connecting to a single phase charger (7.2kW) then you'd use your new cable.

If you buy a three phase 32A cable, then you'll get the maximum possible charge rate no matter which type of charger you are using, plus you only have to carry the one cable.

This is the one I recommend:-


(Type 2 to Type 2 Cable – 4m – 3 Phase)

A single phase cable is barely any cheaper anyway, so in my opinion, it's pointless.

Perfect, thanks for confirming Steve. 3 phase 32A cable it is then. And thanks for the link (y).

Just wish PS supplied the appropriate cables for the appropriate market - how hard can that be? If they supplied a 3 phase 32A cable rather than a 20A cable then everything would be fine.

Anyway, your help and advice is much appreciated. Thanks again.

I don't think it was deliberate. Three phase charging is common pretty much everywhere else in Europe. The beancounters probably saw they could save a tenner not realising the consequences.

What is surprising is that they are -still- delivering this inappropriate cable with UK cars when they are now well aware it's not ideal.

The Polestar person that I talked to this morning acknowledged that it was a known problem and that they were investigating it - I'm not sure what there is to investigate other than replace the supplied cable for the UK market. Either way, they currently have no planned solution and their advice is to buy a 3rd party 32A cable. Its a real shame as it takes a little of the shine off the experience for the sake a few quid. People like me would also be lost if it wasn't for more knowledgeable helpful guys like yourself.

One thing you might be able to do is sell your 16A cable on eBay or something - to recover some of the cost of the new one. But if you're leasing, you'll probably want to keep the original cable to return with the car.

To my mind, they are pretty much dooming all non-enthusiasts to a bad first overnight charge experience. Between supplying an inadequate cable (which will be used by those who don't buy a tethered charger for home) and setting the default charge rate to 6A (which their own car delivery guys are saying is best to leave alone!), it's guaranteed that the first time the owner plugs it in and leaves it overnight, they're going to come back to a barely charged car the next day. This is really dumb - get the first experience right, then people will accept foibles if they can fall back on the basics working. Poor effort, Polestar!

That's odd. I had mine set to 32A at the time of handover and I was recommended to keep it that way by the handover specialist. But, since I want to charge my car as much as possible overnight to make use of cheap electrons, I reduced it to 6A as soon as I came home. 🙂

I have to agree. As a non enthusiast I never in a million years anticipated getting into all this. I, maybe naively, was comparing it to being similar to buying a new mobile phone - as it in would come with everything I needed to use and charge it effectively (once I had got the home charger installed). I never even knew that there were different "phases" and I never thought I'd be having to ask online forums about which different types of additional cables I'd need to be to buying just to use the car in the way I was planning.

What makes the matter worse is that after contacting Polestar directly they clearly aren't interested and just told me to go and buy a 3rd party cable. Great Service :(!
