Designing an On-board Charger to Efficiently Charge Multiple Electric Vehicles

An on-board charger for efficiently charging multiple battery-operated electric vehicles (EVs) is introduced. It has evolved as a single-input dual-output (SIDO) integrated boost-single ended primary inductor converter (SEPIC) fly-back converter, offering cost-effectiveness, reliability, and higher efficiency compared to conventional chargers with equivalent specifications. The proposed system includes an additional regulated output terminal, in addition existing terminal the EV battery of 4-wheeler, which can be used charge another battery, preferably 2-wheeler. With aid control techniques, unity power factor operations are obtained during constant-voltage (CV)/constant-current (CC) grid-to-vehicle (G2V) operating mode. Using mathematical modelling analysis, developed Matlab/Simulink environment, results validated real-time simulator using dSPACE-1104. employed batteries two EVs capacities 400 V, 40 A · h 48 52 4-wheeler 2-wheeler, respectively. Its performance investigated under different modes over wide range supply voltage variations ensure safe reliable operation charger.
