EVSE - 400V/16A to 230V/32A Does such a thing exist?

[Lykke]

We just order a solar orange BEV , unfortunately delivery is not scheduled until December :|

Meanwhile I am looking at acquiring a suitable EVSE and would like the possibility to charge with 7.4 kW, only in Denmark you are not allow to have a phase imbalance of more than 16A.. and that will give me a modest 3.6 kW charging , almost no better than the standard type 1 cable.

In principle, I guess!, it should be possible to convert 3 phases/400V/16A to 1 phase/230V/32A Does anyone know if such an EVSE exists?

Hej Lykke
Dejligt at se en dansker mere..
Jeg mener lige at have set reklame for en på Facebook idag. Tror det var dansk elbil alliance eller ?? Kigger lige efter det.
Men det kræver så du har et 3 faset 16A kraftstik ledigt.

Hi Thomas,

Thanks for the tip; I think it is a very smart and above all flexible charger for the road, but I do not think is solve the phase imbalance issue for my domestic installation, i.e. I would probably not be legal to use it for charging at 7.4 kW because it will draw all the current from one supply phase only

I have a bad feeling that there is really no way to make a legal 7.4 kW-1 phase domestic EVSE in Denmark

Ja, dejligt med landsmænd! Nu kan vi også snart komme rundt i landet med den serie a ladere som EON skal stille op langs motorvejene.

You could do it with a transformer I think, but that would be expensive, and it would waste some energy from internal resistance resulting in heat.

A consult with a local electrician may come up with a viable result. Actually, the BMW dealers should have an idea, as I'm sure this issue must have come up.

Yes, that is what I was thinking, but I have not been able to find this type of EVSE and I am starting to think that they do not exist .. and I am not really into building my own EVSE

I talked to BMW who have only a very limited knowledge about this subject. The local power company seem mostly interested in pushing their own product, hence I feel the need to pull a lifeline to all the EVSE experts on this forum

Welcome aboard Lykke

I live in Farum and will recieve my i3 BEV in less than a month

I was wondering the exact same thing about getting to charge with 7.4 kWh. I guess it should also be possible to convert 3x16A to 1x32A ore something like that. I think the reason why this product does not exist is that it is only in very few countries we have this rule. A 3x32A -> 22kW Combo DC conver exists but is overly pricey.

I think it is more likely that we will see such a product go down in price.

Thanks Palleraa, I live in Brønshøj, look forward to seeing you on the "Hillerødmotorvej"

I have decided to prepare for the future and solve the problem by installing a 22kW EVSE, http://www.wallb-e.com/shop/,; fortunately we have a 3x50A supply line. The installation is completely legal and I guess I am allowed to use it as any other plug in the house, though it may be wise not to start an enquiry
