The controller in our five year old Wallb-e EVSE has developed some issues and I decided to future proof the EVSE and replace the old controller with an OpenEVSE v5 controller.
I have been reading up on the very nice development work done here and it leaves me with two questions:
Is it required to have a lock on the female connection? Our EVSE has a lock on the female connection. The pictures of the OpenEVSE build seem to show a connection without at lock. I guess the lock is not strictly required as the connection to the proximity sensor will become open if one where to retract the cable during charging.
AC-filter. What’s the practical function of the new AC-filter - is it just solving a certification issue? I do not see any of the OpenEVSE 3-phase diagrams showing this filter?
