EVCS with Phase Switching - Always falls back to 1P when Car drops current for short time

Q&A and troubleshooting EVCS

Hi,

some Cars seem to tend to drop charge current every some minutes for a very short time.

So then the following behaviour occurs:

When charging with fixed setting, indepent if 1P or 3P, everything is fine. EVCS works perfectly with using Sun Energy and controls amperage to get the best result.

But when using automatic Phase switching, this works great until car drops current:

  • It starts with 1P and goes up with current
  • Switches to 3P and charges with indreasing current
  • Until the car drops current for some seconds: This leads EVCS to switch back to 1P…
  • 1P current is then increased again, switching to 3P and so on…

Can there be a timeout set for switching back from 3P to 1P? So that EVCS ignores the short current drop of Car?

best regards,
Daniel

Which version of EVCS supports phase switching? I have been putting off purchasing one because I thought it does not have that feature (+RCD).

All Versions of EVCS, you just have to change the contactor inside. Search for it here in the Boards, there is a description.
