OpenEVSE provides electric vehicle charging solutions worldwide based on SAE J1772 and IEC 61851 standards. The ultimate test is, with both power off and the vehicle disconnected, there should be no continuity between the relay contacts. I’m using it nearly every day and I really like it but when I opened the case recently, I discovered that the bottom left side of the relay is getting very hot (50+°C), up to the point that it is damaging the connected wires nearby (see photo: we changed wires and replaced ferrules 1 week ago but the plastic parts are now The relay circuit uses 2 2222 NPN transistors to switch 12V to the relay(s). From there, each leg is fed into an S1M diode and the two are merged together. Dec 8, 2021 · This repair procedure applies to any OpenEVSE with an open-air relay (contactor) such as the 50A - Struthers - Dunn. Using 2 relays allows the self tests to be run one leg at a time avoiding powering the J1772 handle during the test. 0B2 OpenEVSE supports both 1 DPST or 2 SPST. The relay is the only part I haven’t replaced! Another edit: Dec 20, 2015 · It also has an opto-isolated voltmeter, which allows OpenEVSE II to monitor power consumption rather than just current. Our experts provide components, software and services to accelerate the development of new charging technologies. OpenEVSE performs extensive self test during boot, before closing relays/contactors and while operating. Display shows 'RELAY ERROR', EVSE cannot energize output even though contactor is not welded. . Installation Installation should be undertaken by a qualified electrician. Change from 2 single chanel opto-isolators for AC detection to 1 dual channel. It arrived with a bad controller, which you replaced, and then the WiFi module kept hanging and so I replaced with the Ethernet module.
