Anyone doing continuous monitoring of resistance across battery pack to provide warning system of terminal conductivity degradation?
for example, measure resistance of pack including all cells and busbar at 100% and compare from cycle to cycle. if pack goes from 20mOhm at 100% to being 46mOhm at 100% then operator can confidently say either cell or busbar resistance has increased.
i write firmware for arduino and it’s fun, wondering if anyone else using AC resistance measurement principle
