This paper describes the design and functioning of a modified SEPIC converter-based bidirectional battery
charger for a variety of electric vehicles (EVs). The diverse variety of EVs comprises an electric two-wheeler (e2W)
and an electric automobile. As a result, a modified SEPIC converter is designed to charge both an e2W with a 72 V
battery and an electric automobile with a 240 V battery. The presented battery charger has the significant advantage
of complying with the IEC standard in addition to providing good charging performance. Furthermore, the
redesigned SEPIC converter-based battery charger offers bidirectional operation. The efficiency of the given battery
charger grid to a vehicle (G2V) is tested using the optimal grid voltage. Furthermore, the charger's efficacy is tested
using amplitude fluctuations in grid voltage. Finally, the given charger is evaluated for a vehicle-to-home (V2H)
operation to demonstrate the efficacy of the bidirectional operation.
