So we just bought a 2023 Kia Sportage hybrid. It has the state of charge meter (SOC METER) that shows what the charge level of the high-voltage battery is. While driving, it varies a lot and I am wondering if that is normal. it has 4 segments, it moves from the 1 to 3 in the matter of 10 minutes. Then it will go way back down, then it moves up again quite rapidly. Is it normal for it to vary that much?
