Should be fine.

Small generators can be a bit unstable, but large units like that are routinely used to supply office buildings and the like, full of PC's and other equipment with electronic power supplies. They are usually very well controlled.

One consideration, will be wether the generator actually has sufficient spare capacity to charge your car.

The charger pictured seems rather expensive, you can probably build your own for less.

Do you actually need three phase charging? you can simply charge with a normal single phase EVSE if you like.

 

In principle, what's to stop someone buying a 3-phase Rolec "wall-mounted" style charger, and rather than mount it on the wall, simply carry it around as a portable charger? Might be a bit bulky, but surely all you have to do is wire up a 3-phase plug to supply the input power, and job done, no? Got to be a lot cheaper than that box! Rolec have a fixed output current they offer, but it's a simple job <£100 to replace the controller item inside with a Mainpine one, which can be set via a bank of resistors & a rotary knob to vary the allowed current from 6A up to 32A in steps of 1A, if you want that flexibility.

 

The only slight issue is those rolec 3 phase units dont have a built in RCD/RCBO. But otherwise, yes thats one solution.

The reality though, is that you might as well just buy the mainpine, a contactor, and an RCBO and mount them up yourself into a decent enclosure, and it'll almost certainly be cheaper than even the 3 phase rolec unit.

 

You should be fine as long as the generator is earthed and bonded correctly. i.e. The earth and neutral of the generator are bonded together at the generator and connected to a local earth rod.

 

Yeah I'd question your "need" for 3 phase power, and high charging rates. Any EV will also charge from a normal doemstic socket (slowly!) but if you aren't doing big miles during your week this should be fine?

 

My understanding is that the rectifier circuitry in the Zoe is particularly inefficient when charging slowly. As such it may be more sensible to charge quickly at 32a or 16a three phase rather than hang it on one phase for ages - especially if this was out of hours when the generator would otherwise be shut down.

3ph charging would probably also present a better load to the generator as well...

 

to answer your question the Zoe does indeed charge up to 43kWh 3 phase (depend model) while the Ioniq can't (only 6.6kW AC)

 

Many thanks all, some very useful information.

I want to charge as quickly as possible as not to cause an inconvenience. Having a genny powerful enough for 32a 22kW at my disposal, I want to make the use of it.

The self assembly unit sounds intriguing!

 

Opened do a kit which might be suitable:

thats not 3 phase...

if you want a kit, evbitz do them:
