Cell Balancing #4

Open aaronsb opened 11 months ago

I think it still makes sense to try and attempt cell balancing even with the constraints placed on the BMS board design. In many real world scenarios, it could be days to a week or so between uses. Any balancing attempts within the safe current limits should be beneficial.

Additionally, units stored without use for longer intervals benefit more, due to the likelihood of high power intermittent usage are likely to unbalance the pack, and therefore a need for cell balancing even more. The extra time available stacks up the likelihood of successful balancing.

Hi Aaron,

Thanks for your comments. I think, overall, I agree. It would need a new state adding to the BMS state machine - ie BALANCING. However, I don't think I'll have a chance to do this in the foreseeable future.

If you fancied having a go, and did make a patch, I'd be happy to review and merge it :-)
