Another BMS recall for the Kona

[KiwiME]

Wow, both of you need to do some serious ‘learnin. I’d suggest this Channel on YouTube.

In order to evaluate the condition of our cells and the effectiveness of our BMS in re-balancing the cells I would like to be able to see the change in individual cell voltages while the BMS is performing its magic.
Anybody have a method to do this without having to crack open the modules and attach measurement wiring to each cell?

Additionally, if someone has collected real data that could be used as a comparison benchmark, that would be extremely helpful.

Car Scanner does a great job doing that.

Thanks. I assume you are using Car Scanner to monitor your cells.
Have you ever observed/recorded the balancing in progress?

Only when charging and observation only.
On the 2024/25 pack, the cells are 1P, not 3P as previous years, so the voltage differential between them was easy to monitor.
