Constant Current - voltage with Maximum Efficiency Inductive Wireless EV Charging Control using Dual - sides DC Converters

摘要

This paper presents a design of a 2.0kW at 160 mm of transmitter (TX) and receiver (TR) distant CC-CV with maximum efficiency EV charging using dual side dc converters. The method was validated using MATLAB programming. In cases of variations of the input voltage, load resistance of battery state of charge, and the TX-TR offsets. The results found that the uncontrolled wireless EV charging makes over-input current, output voltage, and overload output power and unbalance of input and output currents and voltages. The CC-CV wireless charger applied the constant current then constant voltage but the input and output currents and voltages are unbalanced. Finally, the CC-CV with maximum efficiency wireless EV charging can be operated in constant current and then constant voltage with balanced the input and output currents and voltages.
