Hi did you find out what was causing the 2 minute charger cycling for you?

Correct. This is why ZOE cannot charge on floating networks, such as they still exist in some isolated areas in i.e. Belgium and Norway.

It injects a current between the N and PE and measures the voltage. This is done after the car commands contactor closure to the chargeing station (of course), but before the actual charge is started. See second graph, top trace https://canze.fisch.lu/charger-startup-sequence-the-measurements/

Do you have an idea on how the car can do this?
The only way I can think of is that the car assumes that the neutral has the same potential of the far ground.
According to this assumption, it could measure the earth resistance as the ratio of the voltage between earth conductor and neutral, and the current flowing in the earth conductor.
What’s do you think?

Thanks for your reply. I have tried to add an EMI filter but I still can’t charge my ZOE normally (stil stopped after the 2-minute interval). I have checked the energy meter and checked the command from the charger, the charger output below 30 Amps, so it would be output more than 32A. I may try to keep updating you guys.

Thanks all!

Be careful now. Earth leakage is a current from the mains to earth because the entire circuit has an electrical capacity to ground. This is found in the Leak Currents screen in CanZE for different frequency domains. HF should not go above 300 mA (but to be honest, I doubt it will)

Earth line resistance is a totally different thing and is tested by the car before charging starts, so this is not your problem and checking your earth line will almost certainly solve nothing.

Given the 2 minutes interval my bet is on the charger itself (not the car) deciding the car takes just a bit more than 32A (which is allowed by the standards, 5% I think) and stops charging. Check by going to another 32A single phase post.

Okay, I would check my power source, since it’s quite “dirty” I would say, harmonics are everywhere and they are great in magnitude.

Thank you so much for your answer!

Yes, then earth leaking is very probable I would say 😉

It would stop again after 2 minutes, it just goes on and on
