For the last 5 years I've had a Clipper Creek EV charger that I used to charge my Model 3 without issue. Recently, I had a second 240V NEMA 14-50 plug installed in my garage. The installer ran a subpanel into the garage with a 100A breaker from the main, and then has each NEMA 14-50 on its own 50A breaker within the subpanel. I am now using the Tesla mobile charger with 240V plug to charge the Model 3, and the Clipper Creek charger to charge my wife's Honda Clarity. When using them one at a time, they work perfectly. However, I noticed today that when I tried to start charging my Model 3 while her Clarity was already charging, the current was fluctuating up and down, as high as 20A and as low as 0A, back and forth. The car or Tesla charger were not reporting any errors. So I started to investigate. I unplugged the Clarity, and then the Tesla locked right in at normal max amps that I have it set at (24A). I then plugged in the Clarity, and the Tesla started to fluctuate current again.
Any ideas what is going on? Both circuits are on separate breakers in the subpanel and appear to work properly when used by themselves. Also, voltage appears to be solid at 240V on both according to the app for each car.
Thanks for any ideas that you have!
