So something "interesting" is happening with my Tucson 2025 PHEV. I am running down the EV charge for local drives, which drains the battery to 13/14% (at that point the vehicle switches to Hybrid). To recharge I use the Hyundai Level 1 charger at home. It is set to 12 amps (the highest setting). The first two times I charged my Tucson, it took about 10 hrs, which was expected. Then yesterday, it needed over 11 hrs to charge. Today I come home with 0 miles EV remaining and a battery charge of 14%. I plug it in and it says it needs 12hrs, 20min. I don't mind that it takes 12 hrs, but that is an increase of 2hrs within 4 charging cycles. What's going on here? I always use the same outlet, nothing on this current in my house uses any significant amount of electricity. Also, there is a Tucson setting to limit the charge when charging, and I am having this setting at 100% (no limit). Any suggestions?

Best guess, how much is it discharged is not precise in the readings. Maybe it was drained more the last two times?
You say nothing significant on that breaker, but really best to have nothing else used on that circuit.

Temperature difference? The battery monitoring system might be limiting the charge current for a while due to elevated temperature (maybe you ran the battery down harder or faster than usual?), although that's hard to fathom with only 1500 watts of charge power to begin with. The main thing to look for is a change in EV range.
