EV showing 0.0 even after full charge?

Something else just occurred to me which may or may not be relevant. One time I had my Siemens level 2 go into "fault" mode when I plugged in for no apparent reason. I reset the charger and was fine, and has been fine since, so I have no idea what was up with that--maybe it was just a funky electrical connection for an instant, or maybe there was some moisture in the head or something.

In any case, I've never used the included charger so I have no idea how it might handle a similar glitch, but if it automatically resets at some point I could imagine that something similar might have happened that caused it to stop trying to charge, and it reset automatically when disconnected, and you wouldn't have noticed if you didn't look at the lights on the charger.

If it never happens again, maybe that was it. If it does and you can confirm an error on the charger, maybe something has a bad electrical connection (the previously-mentioned faulty charge cord).
