Often cell datasheets are limited in data, particularly when it comes to internal resistance. So how do we go about estimating cell DCIR? Although cell datasheets don’t explicitly give the DC internal resistance of the cell, they do often show the voltage versus SOC discharge curves. Within this data is the DCIR value for the … Read more
