I've had a Gen1 (80amp) HPWC and P85D (dual 40 amp chargers; MCU1; software 2020.48.37.6) for about 6 1/2 years now, and never had a charging issue until the last couple weeks. The car's now refusing to charge on the HPWC -- I get the message: "AC charging interrupted -- Check power source and charging equipment." I have the HPWC limited to 64 amps. I always get a green light (never red) on the HPWC. I've tried resetting the car, resetting the wall connector, resetting the circuit, same result each time. I even put the HPWC in test mode (via internal DIP switches) and confirmed that its contactors work as expected.
I confirmed no issues on the mobile charger (though I can only test it on 120V@12 amps). I also tried a friend's 3rd-party 240V 30amp charger without issue.
What I'm trying to figure out is what's potentially gone wrong: has one of my on-board chargers died or is it the HPWC itself?
I believe that my dual chargers normally split the incoming 64 amps of AC, so it runs 32amps though each on-board charger. What I don't know, however is how the car handles a load of 40 amps or less. Does it push it all to one charger or does it split it to both? Similarly, how does it handle a 120V load from the mobile connector? Does it use only one of the chargers?
The reason I want to know is because it's possible that if any load 40 amps or below is passed to the one 'good' charger, I could simply have a bad on-board charger while my HPWC is fine.
Alternately, if the car splits literally *any* load across each charger, then it would suggest the HPWC is the culprit, as other chargers seem to work fine.
