I am working on Simulation Model based Lithium-Ion Battery Development with MATLAB/Simulink. For the battery model, I need to define Intial Charge Deficit , which is a phenomenon which every battery undergo due to its default 'Self-Discharge' characteristic. So, ultimately i need to calculate - the charge which reduces due to this self-discharge initially and causes a minor change in the value of Rated Battery Capacity. However, after reading several papers, I found that one way to calculate this is by the following formula - Q_initial = 0.5 * mean (Battery_Capacity) [where Battery Capacity is an array of capacity value measured at 3 different temperatures).
Similarly how to calculate initial State of Charge, after subtracting the self-Discharge value.
Please Clarify .
