Is anyone interested in this EV tester device?

We built this board for internal use so our engineers can test chargers without needing a real EV most of the time. It simulates the EV signals only, including fault injection. The purpose is to test the real level 2 chargers without an EV.

Curious if anyone else would want one. We're happy to open source it once the final tweaks and testing are done. If there's enough interest, we might also sell it assembled with a 3D printed enclosure. Parts alone run about $150, and $85 of that is just the Type 1 J1772 inlet. The device can be remote controlled over WIFI.

What EV charging O&M issues are eating up all your time right now?

Hey everyone. I work on the networking and security side of EV charging infrastructure, and I'm trying to get a better sense of what real-world O&M teams are actually struggling with the most these days.

I'm really curious what specific issues are taking up the bulk of your time out in the field. Are there certain types of connection drops or bugs that are just notoriously difficult to diagnose or reproduce? I also imagine it can be a nightmare trying to figure out who is actually responsible when things go down—how often do you run into incidents where you can't tell if it's a charger hardware fault, a CPO backend issue, or just a bad cellular network?

Would love to hear some war stories or hear about what's causing your biggest headaches right now.
