I Can’t Charge My Kia EV9 Over 80 kW—Fast Charging Constantly Fails on Long Trips

Hello everyone, I’m the owner of a Kia EV9, and I’m extremely disappointed in the car’s charging performance, especially during long-distance travel. I purchased a 22 kW three-phase AC charger for home use, expecting it to fully utilize the vehicle’s capacity. However, my EV9 won’t charge beyond 11 kW on AC, which was already disappointing. Things got worse when I ventured out on a long trip.

Every time I tried using DC fast chargers rated between 120–180 kW, the car threw up charging errors and failed to charge. After several failed attempts, I realized that the car consistently malfunctions on chargers above 80 kW. If I keep it below 80 kW—say at 60 or 11 kW—there’s no issue. But what’s the point of owning a modern EV if it can’t handle highway charging stations, which mostly offer 120 kW and above?

I even stopped at the Kia authorized service in İzmir on the way, hoping they could fix the issue. Unfortunately, they couldn’t diagnose the problem, only suggesting a software update that might help—something I couldn’t wait around for during my travels.

This is not what I signed up for when investing in a top-tier electric vehicle. Kia needs to take immediate action to fix this widespread charging issue via a firmware update or hardware replacement. EV9 owners deserve reliable fast charging, especially when traveling long distances.
