I set a charge timer in my 2017 Nissan Leaf S. The car wasn't supposed to charge yet--it would start in a few hours, but I sat down in my car to check some things. I turned the ignition on, and I started hearing clicks from the battery relay every ~3 seconds or so.
My OVMS started sending me notifications, approximately once every 3 seconds that "Charging Stopped". I don't know if the relay has a max number of cycle times, but I heard it might. The car was at ~35% SOC and was configured to stop in OVMS at 69%, so there's not any reason for OVMS to even stop the charging--it wasn't even above the configured SOC.
Disabling "Sufficient SOC" stopped the "Charging stopped" notification and the clicking.
