Design and Operation Verification of Integrated Battery Assembly Charger Using Cockcroft Walton Circuit

Abstract

The new concept of charger for lithium ion battery assembly with several unit cells has been proposed and tested. The Cockcroft Walton (CW) circuit developed as a high voltage multiplier was applied for the battery charger of lithium ion battery assembly. The some capacitors in CW circuit were substituted with unit cells to design the charger circuit. This charger circuit worked well for the individual unit cell of integrated battery assembly. It is also considered that the wide application is feasible because of its simple circuit.
