Kia e-Niro MY20 64 kWh - Gravity Blue
Yes it can, but it'll not balance when it's below its defined 100% SoC. The Kia Connect app even has an indicator on the status screen that indicates 'balancing'. The battery icon will blink or something like that. You can also check what's happening once 100% is reached. You'll see the charging voltage drop since at that moment the BMS starts balancing the cells and will try to bring the lower ones up to the voltage of the higher cells. This process may take a couple of minutes or an hour, depends on the state.Which manufacturer is advising charging to 100% regularly to ‘balance cells’?
And how does that square with the fact that you can’t charge a BEV pack to 100% anyway, Tesla excepted?
Ergo, the BMS can balance at less than 100%.
Another indicator that it does not balance throughout the charge is that once cells are un-balanced (check via an ODBC reader), they will remain unbalanced until you charge to 100%
