Loxone EV Chargers

[Ricardo Tavares Dias]

Hello,

I am considering a new EV charger (for a new house build) and wanted to ensure maximum charging capability for a 3-Phase system: 22Kwh

Unfortunately Loxone's chargers won't go above 11Kwh...

Can anybody explain if this is by design or simply because whoever is actually building those chargers doesn0t go above 11Kwh???

Very frustrating, and probably will have to try to integrate a 3rd party charger instead.

thanks,

Ricardo

Hi Ricardo,

Apologies but I am going to answer a question with a question - Do you already have an EV car? 

If you haven't done so already I would check whether it will charge at 22Kw AC as most people assume they will but it does vary massively - My Renault Zoe will charge at 22Kw but I know customers with Polestar 3. Mercedes EQC400 and BMW I4's that cost a whole lot more to buy that will only charge at 11Kw AC 3phase no matter what they are plugged into. 

When it comes to AC Charging there isn't a huge appetitte for 22Kw charging amongst the car manufacturers, if I had 3phase and it was a necessity to charge a car rapidly on a regular basis then I would probably shell out on a DC charger but those are going to be about £5K installed

Yes Paul, I know where you're going.

An example is that my wife's Volvo EX40 launch edition (which was still called XC40 EV) supports 22Kwh charging, and we do have a 22Kwh charger in our current setup.

However newer models don't; it seems like the manufacturers are leaning towards saving a few bucks and installing lower rated BMS units.

The following list clearly shows models known to support 22Kwh AC charging (and others):

• https://www.evspecs.org/electric-cars-ac-charging-comparison

• 
  

• To your point, many of the top brands, like Mercedes-Benz and Porsches only support 11Kwh...
  Even large battery packs, like the Rivian R1S/R1T Max only support 11Kwh, which is a very questionable decision for a car that has a 14oKwh battery!

Notably, the zippy and revolutionary Renault Zoe not only supported 22Kwh: some models even supported 43Kwh AC charging during some time, which shows that it's possible to do more.

I am about to acquire a newer EV (for myself) that I expect to support 22 Kwh charging, let's see.

Anyway, for future compatibility, I think it would be very nice if Loxone would support 22 Kwh.

I hadn't realised the Zoe would charge at 43Kw AC but then I have yet to find an AC charger near me that does 22Kw AC that likes a Zoe!! If not at home I only use DC charging.

From what I have seen and talking to some car dealers I think support for higher rates of AC charging moving forward is very unlikely given that most older housing stock in the UK (I know 3phase is more common in central Europe and Scandanavia) is on a single phase supply and will be limited to 7Kw come what may.

Even in new build trying to get 3phase is a challenge - we weren't allowed a 3phase connection on our new build which is on the periphery of a 200 house developer estate.

Any new public charging that is going in at the moment is DC so i can very much see the manufacturers keeping the AC charging low and as you say saving some cost moving forward.

Last week Loxone announced a new 22Kw wallbox that will go on sale in September assuming it gets the relevant UK regulatory approvals.
