Modeling of a power converter and investigation into EV battery optimal sizing and parameter estimation for charger stability

This work presents a novel approach to characterize Li-ion cells for EV purpose while adhering to IEC62660 standards. A suitable EV Battery is assembled using standard EV cells and characterized for its internal parameters. A suitable converter is designed and analyzed for its small signal operation to charge the EV Battery. CCM mode of operation is verified and stability analysis is performed using MATLAB/Simulink to ensure stable operation of the circuit in CV mode.
