Homecharging in NL: 7.4 kW on 3x25A

Post by Ben Fortuin » Wed Jan 09, 2019 10:48 am

Home charging in the Netherlands can be a problem.
A common home connection has 3x25 Amp. With this you can charge with only 3,7 kW
Upgrade to 3x35A increases charge speed to 7.4kW. However this will cost €800/year extra.

With Magnum 8kW charger you can charge 7.4 kW in a common 3x25 A connection.
This charger takes 2 fases of 16A and turns them in a kind of super fase.
I manage to charge my Ipace at 7.2 - 7.4 kW with this Magnum charger.
It's not the cheapest charger (€1675), but it does the job perfectly.

Why is there a 16A / 3,7kW limit on a 3x25A connection?

My charger is configured to take 24A max, resulting in 5,5kW. In most days, I don't arrive home completely empty NOR need the car completely full next day as well. So 5,5kW is more than sufficient for me. And for the few days a year that this is not sufficient, I will take the public 22kW charger over night, which gives me even slightly (7,5kW) higher speed than your Magnum.

So I don't see any need for the Magnum charger in my situation and don't understand the 3,7kW limit you suggested.

Last but not least for me, Magnum doesn't support automatic compensation for electricity cost via lease company.

I've got only 1-fase 35A at home, but using Domoticz with a P1 cable see that when the car is charging at 7kW, we have the induction cooking plate, oven and dryer on as well, during 10 minutes the house uses 12kw....and there is no issue with the breaker...using 52A in total for a short period of time doesn't seem to be an issue.

I got a similar restriction in Austria from the electricity provider. They call it "unbalanced load problem" and you are not allowed to use more than 16A on just one of the 3 available phases for an extended period of time. In some rare cases they give you a permission for 20A unbalanced load but this is not the usual case. Btw: we have 3x25A standard connection for normal houses/flats, in some cases 3x35A. I gave up the discussion with the electricity provider because as an end customer at my place they won't give you any chance to get anything better for such a situation.

I am fairly sure we don't have that limitation in NL. It is limited to multiple times 16A max, unless you apply active load balancing to ensure a 25A max current, therefore 24A is allowed for my charger including Dynamic Load Balancing combined with a few 16A fuses for other stuff that is turned off during most of the day.

Thanks for sharing Ben. There is a lot of discussion in the home charging topic viewtopic.php?f=8&t=310 also about the Magnum.

One of the warnings there was that is was inefficiënt in energy consumption andthe device getting very warm. And that the setup did not support a measurement option where you could bill the used KWs from the the owner of the home (private) to the owner of the car (often the company). What is your Experience with this ? Im very curious.
