The Internal Resistance of the pack is calculated based on how the voltage fluctuates when current is applied (E=IR).

This parameter is the percentage of the battery current limits used in the calculation of internal resistance. The percentage will take into account limit degradation due to temperature conditions. The ideal percentage is primarily based on the accuracy of the current sensor used.

Unless you know what you are doing (or were instructed to change it) this value can likely be left at the default setting.

Example: If the maximum DCL is 100 amps and the resistance evaluation amperage parameter is set to 40%, then the BMS will look for a delta amperage of at least 40 amps (40% of 100 amps is 40 amps).
