I'm still struggling with Control Pilot issues.
As far as i know the only 'valid' CP protocol is defined in J1772.
The European IEC 61851 equivalent is supposed to be using the same standard.
For some reason some public charging stations /EVSE's (in The Netherlands) dont seem to work with that protocol. This means either a different protocol or some undefined tweak or addition on the J1772 protocol.
After calling with several different public charging station service providers they cant give me the answer as why some EVSE are working and others are not.
At this point i'm trying to build some sort of diagnostic CP device using an Arduino to measure the different CP voltages and PWM signal on different EVSE's according to the J1772 protocol.
Can anyone tell me if there are other protocols to look at ?
