I’m no technical guru so I won’t get the language right.
We had a 22kw 3 phase Evnex unit installed in January. We’re happy with it and solar charge works well.
On the occassions where we’ve had to “charge now” I was expecting it to fill up at the speed of 22kw/h. However, it only goes in about half of that (just under 11kw/h, see image of today).
Is this a setting on the Evnex unit? I can’t see any limit that’s obvious on Evnex or car.
Any help is greatly appreciated
I don’t think the charger would be limited in this way though I would need to know the serial number of your charger to look this up to confirm (it’s on a sticker on the right hand side).
There are therefore a couple of possibilities of what else might be happening:
I don’t know what vehicle you have, but the most likely limitation is that it has a maximum AC charging rate of 11kW (note this will be different from the maximum DC charging rate).
You may also have a cable that only allows up to 16A on each of the three phases, which would also limit you to only 11kW.
Serial number AV23020130 (I think, there were quite a few numbers)
Car is MG ZS EV (built SEP '22).
Cable is whatever one came with unit.
The MG ZS has a maximum AC charging rate of 11kW so that will be why it doesn’t charge any faster.
The cable supplied will be a 32A cable so would charge a 22kW-capable car at that speed.
I’ve also checked your charger and there is no restriction on the current.
Understood. Thanks Tom.
I didn’t know about the AC vs DC charge rates prior to purchase of the 3 phase unit (vs single phase). At least I can take some comfort that it’s charging a little faster than a single phase 7kw unit.
Thanks for clarification.
