Constant current (CC) and constant voltage (CV) charging of batteries is a crucial research area in the practical implementation of wireless power transfer (WPT) systems. The typical charging process of a battery starts from the constant current mode. As the battery’s voltage increases, the charging mode switches to the constant voltage mode.
This paper + presented the design of a constant-current/constant-voltage charging control strategy for a battery cell using the so-called cascade control system arrangement with the adaptation of the battery charging current based on the open-circuit voltage (OCV) parameter estimation.
The operating resonant frequency in both modes is the same. This paper proposes a PV-integrated five-legged inverter for a constant dynamic wireless charging system with a receiver-side tuned resonant network. This receiver-side control ensures constant current and voltage charging with transmitter-side series compensation.
The 0.75 A constant current output is achieved when the load varies from 10 to 15 Ω, and the 12 V constant voltage output is achieved when the load varies from 16 to 25 Ω. Initially, the CC-CV charging strategy based on SPWM inverter control was tested at a transmission distance of 3 cm between the transmitting and receiving coils.
The 3.3 kW five-legged inverter is developed to energize the four double-D-shaped charging couplers. The common DC bus delivers 350 V to the inverter, and the charging system delivers 350 V, 8.85 A to the EV batteries. Achieving a sustainable future requires collaboration to adhere to the Paris Agreement 1.
To maintain a constant voltage, the charging current is proportionally decreased until its value reaches the minimum battery charging current A. Thanks to the improved control algorithm, no voltage and current transients are observed during the transition from CC to CV phase. 5. Experimental Results
