Sinusoidal Charging for Li-ion Battery

The purpose of this thesis is to develop a sinusoidal charger that can track the optimized frequency of Li-ion batteries. In this study, the optimized AC impedance frequency tracking is firstly carried out for various types of lithium-ion batteries with different aging degrees to achieve the goal of shortening the charging time and increasing the charging efficiency. The digital control core of the charger developed in this thesis uses the F280049C digital signal controller (DSC) produced by Texas Instruments and adopts the Powell algorithm to quickly search for the best sinusoidal charging…
