This paper introduces a sliding mode control (SMC) approach for the bidirectional DC-DC power converter in a Battery Electric Vehicle (BEV) charger, aiming to achieve accurate tracking of desired current and output voltage in both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) modes. BEV chargers play a pivotal role in enabling two-way power communication between the grid and the vehicle, but effective power flow control poses challenges. SMC offers a practical solution by leveraging the advantages of DC-DC converters and simplifying hardware implementation compared to traditional Pulse Width Modulation (PWM) techniques. The proposed approach incorporates an integral-proportional controller for output voltage regulation and a sliding-mode controller for inner current loop regulation. Stability analysis is conducted for step-up and step-down operation modes, and simulation results demonstrate the effectiveness of the proposed controller in both G2V and V2G applications.
