Easee charger 1 and 3 phase dynamic max power

Hi

Anyone done dynamic max power regulation on a easee charger where both 1 and 3 phase loads are applied?

It seems there are alot of information about dynamic limit and tegulating amperage. But this will not work in a combined 1 and 3 phase senario.

I have a equalizer and can regulate max aperage on each phase but again this dont work in 1 and 3 phase. Where max power is decoupled from amperage.

When using 1 phase charging i can allow a higher phase amperage as long as the total kW limit is not excided. Same for 3 phase. By setting a static max amperage pr phase you either get to low output in 1 phase charging or to high when using 3 phase.

How is the regulation best performed when you want to look at kw only and not amperage?

Hi @prilly,

Have you found a solution in the meantime? I have a similar issue: Two Easee chargers; one of them shall charge a hybrid car (on a single phase only) whereas the other charger is supposed to switch to three phased charging when I have enough excess power.

Just like you, I also haven an Easee Equalizer. But I was not impressed by its performance for solar charging, so it has been degraded to only monitor the main fuse.

Right now I am thinking that I should not switch to three phased charging unless there is enough power to charge one car on three phases and the other on one phase. That means that you would need minimum 3x6 Amp (4.140 W) for the first car plus 1x6 Amp (1.380 W) for the other, i.e. minimum 5.520 W before switching one car to three phased charging.

However, once you have switched one of your chargers to 3-phased charging, you have to control both chargers individually, i.e. by using set_charger_dynamic_limit (on both of them individually) instead of â€śset_circuit_dynamic_limitâ€ť.

And then the fun-part starts: to think about all combinations; to determine how many cars are connected and which of them would continue charging if there was enough powerâ€¦

Sorry for lengthy reply, but I am interested to hear whether you have found a solution for yourself (and would be willing to share it ;-).
