4. Determination of model parameters and experimental protocols

4.1 Testing issues

The various types of tests and protocols presented here are designed to implement the battery models described above. The identification of certain battery characteristics is necessary for the development of a behavioral or aging model, or for both. The need for measurements is directly linked to the type of model chosen, its complexity and the range of modeling parameters (temperature, current, etc.), leading to different types of test.

In the case of automotive applications, the ultimate aim of ageing models is always to determine whether the battery pack used will retain sufficient performance over the lifetime of the vehicle (or over a sufficient fraction of the lifetime for the smallest packs in the case of certain HGVs). Given the number...
