1. 1. Design of Resonant Filters for AC Current Magnification : Heating of Li-ion Batteries by Using AC Currents

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nikolina Djekanovic; [2018]
   Keywords : Current control; injection of alternating current; internal heat dissipation; LCL filter; Lithium-ion batteries; power efficiency; resonance phenomenon;

   Abstract : Using alternating current in order to heat batteries at sub-zero temperatures is a method,which is investigated in-depth by an increasing number of study groups. The thesis considersthe resonance phenomenon with the intention to use alternating current amplificationand battery’s impedance in order to induce power dissipation inside the battery, and in thisway increase its temperature.
