1. What are the "all standard J1772 protection systems"? Just that both you mention: ground (earth) verification test and GFCI (Ground Leakage Detection)? 2. There is another problem, my car plug is Menekes, different from that one on the Panasonic EVSE. I would need to exchange to Menekes plug...

I am happy you have a solution for me - thanks!! I will contact you by PM as I have some more questions about that EVSE. EDIT: I couldn't sent a PM. 1. What protections does that EVSE have? 2. What protections do you disable? 3. Here in Portugal, we use Schuko plugs...

BIG thank you for sharing your knowledge and experience Ingineer!! No one here can help me, telling what is the problem. The ground/earth of my electrical instalation is not isolated but it may have a higher value of 20ohms max limit. Maybe I can try open original EVSE and see if I can...

I've been considering this idea and found here that would fail since power lines and earth signal works in a different way. That's what I am trying to do, but my time is very expensive and so I want to build the minimum needed. Most protections on EVSE are already on my electric instalation...

Hello chris1howell!! Thank you for all of your work in OpenSource! - your work inspires me, thanks. I would like to get an "EVSE" small enough and cheap, to fit into a J1772 plug, just like BareEVSE. Also I am not looking for the safety features - thanks to them, the original EVSE that came...

What do you think is the minimum for an EVSE work on a car like mine? I must say I prototyped that small and simple circuit and I couldn't get any wave out of it :-( :-( --- maybe I will go with a microcontroller...

My EVSE, of my Smart electric car still doesn't work. I designed the NE555 circuit so I can visualize how I will prototype it. I also used LTSpice to simulate and it seems to have the output I am looking for - ~5us --> ~8A current charge.

Hmmm, I wounder how did you found I am from Portugal ;-) Your are correct, ground isn't floating but it is connected to the buildings grounding electrodes only, here in Portugal.

THANKS!! I will explore this option.

Can someone please tell me what is supposed that two 100K resistors do? how do they "trick" the EVSE? I am asking this because my Smart electric car EVSE doesn't work on my garage (but works on others) and electrician thinks it is because on some earth bad resistance value. I am in Europe...

Earth resistance value may be a bit out of the max specification.

"buy something that is made properly" ---> can you please suggest me? as I told, the original from my car doesn't work and so I will need to "disable" some safety, probably the earth resistance measure. I have experience to program firmware (for ARM mainly) and I can make my own small prototype...

BetterLeaf, THANK YOU FOR SHARING!! I am a Mercedes Smart Electric car owner and the EVSE that came with it doesn't work on my garage, even after the electrician told everything is ok. But the EVSE works on others garages. I am looking to make a cheap and simple EVSE for me, and I want...
