Maximum Cell Discharge Capability

cell maximum current

Establishing the maximum cell discharge capability is difficult without understanding the design in detail. However, you can work towards establishing this limit with a number of measurements and calculations. The aim of this post is to describe that approach, the underlying physics, some of the measurements and calculations. First of all though we need to … Read more

Estimating Cell DCIR

electrical symbol showing single cell and internal resistance

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
