Home charging in the UK

[Valerian]

That looks like some kind of distributor/installer in the UK. Do you have the model number for the EVSE? Can you take a picture? Does it have a label on it?

Edit: it looks like It may also be an EVSE made by BP, but I can’t get the BP page to load...

Edit 2: page finally loaded, but not much help. I haven’t found any manuals online yet either. I did see a Wikipedia page for the BP Pulse that references the Chargemaster coming in 3.6kW and 7.2kW variants. It’s possible that there’s a dip switch or setting for this on the EVSE...or you may have the wrong unit...? Pictures? Labels?

Edit 3: I did find a forum talking about a setting for 16A vs 32A. May help.

https://www.speakev.com/threads/chargemaster-homecharge-installation-manual.151057/

Edit 4: Post #7 on that thread specifically calls out a jumper that, when removed, reduces output from 32A to 16A.

Thanks I’m still confused why it is so slow. Thanks for searching . Some pictures that may help?

My wife’s charger is one of these and she gets 7.2kw. I’m wondering if there is a dip switch inside that unit that you need to flick to get a higher output??

Thanks I’m still confused why it is so slow.

Power (kW) is the product of current and voltage. If your supply current is limited to half, the output power will be cut in half.

That thread I linked to talked about a jumper inside the unit that, when removed, would limit the current to 16 amps, (instead of the regular 32 amps). So, the first thing I would do is open the unit and check for that jumper.

But you also have to be careful that the breaker it’s running off of is large enough to handle the increased current.

It’s probably best to just have a licensed electrician come look at it for you.

Edit: I’m going to stress getting an electrician to look at it for you. Electricity is no joke.

Thanks. Someone told me “When I’ve seen this before it’s been due to bizarre 3-phase 20A charging cables supplied with some German EVs (won’t charge at 7kW on single phase chargers).” But I used the same cable on Panamera without problems....

So with the same charger snd x as hoes your panamera chargers at 7.2, but your Tayczn at 3 ish?

Not sure if it is relevant to chargemaster but some of the smart chargers have setting in the associated apps.

I have an EO Charger and an Ohme charger. The EO allows the Maximum Rate (Amps) to be set in the app and the Ohme appears to adjust based upon the selected vehicle, with older BMW 330e selected output is at 3Kw. The Ohme also has a setting for 'optimizing for battery life' which I assume slowly ramps up the charge rate.

I think so but as the Panamera only charged to 20 miles it didn’t take long and I really don’t remember it showing 7.2 or 3.... not entirely sure. I will follow up with Chargemaster....now BP Pulse. Thanks all for comments

This charger is from 2015 and I don’t think was that smart....

I now think the answer may be that it is an old cable from the Panamera and some of them were limited to 3kw ......... I’ll ck tomorrow but thanks for help guys.

Yes just double checked in the light and my Panamera cable is 20 amp rather than 32 amp and that seems to the reason for the slower charge. Basically I need a new cable. I see these are cheaper but are they any good? https://evconnectors.com/ev-plug-Porsche-Taycan-4-S-cable?product_id=394

What did you get with the Taycan - charger and cables?

I’m guessing you must have the Porsche Mobile Charger Plus (PMC+) at a minimum if not the Porsche Mobile Charger Connect (PMCC) which would have been supplied with the cables you need.

Why not use either of these chargers in the first instance (and amend supply if necessary / as needed)?

You’ll need 32A supply from your fuse box to get 7.4kW - is that in place (sorry if this has been covered before)?

Thanks. Yes I did get that charger but it looked far more complex than the cable that I used with the Panamera rather than installing that system. In fact I read the instructions and didn’t understand them. Someone has told me they have a spare 42amp cable so think I’ll try that. Thanks.

Oh ok. It's a doddle to install and your current supply cabling will likely provide what you need. Recommend to get a qualified electrician involved to complete the install. From the charger to the car it could not be more straightforward.

If you don't have a 32A supply then regardless of cable you won't achieve the minimum useable power needed to give you 7.4kW (I'm assuming this is all dependent on a single phase electric supply in the first instance). Anything less will limit you to 3.4kW (same as a 13 A 3-pin plug).

It is 11 kwh. 3 phase is 22kwh.
Mobile conector with 32Amp socket if fine for that. I added the extra housing.

Hmmm interesting. Yes I’m sure it says up to 11kw on the web. At the moment I’m thinking I might start with a 32a commando socket for the mobile connect and decide on a fixed charge point in due course. As you say I’ll have to remember to take it with me if I might need it when away from home though. Cheers

11kW requires 3 phase too. Do the math.
