Reply To: SOC estimation industrial state of the art

Mohammed Suffiyan

I have been working as a Battery Architect in the EV industry for about 3 years now. Even today coulomb counting is the widespread SOC estimation technique used because of its’ simplicity in terms of algorithm and also because it is very cost-effective.

I personally am working on developing Kalman filter-based SoX estimation algorithms. I have my cell model and battery model ready with me as of now, this is a challenging task, and once done it will be rewarding as the EV industry now started realizing how important it is to know the states with as minimal error as possible.
