Kia e-Niro MY20 64 kWh - Gravity Blue
Yes, but it will NOT do it while charging to lower percentages than the (virtual) 100%.That’s a conscious choice by Kia, which is fine, but just confirms my point that a BMS can balance individual cells at less than 100%.
I get that Kia call it 100% for ease of understanding by customers, when it’s actually 90% in reality.
I also believe you're overly optimistic about the top buffer. It's a generally accepted fact that the e-Niro has a gross capacity of 67 kWh. So 100% SoC will be closer to 97% than 90%. Good thing is though that the NCM622 chemistry has a better resistance to high SoC than NCM811.
