Item type:Publication, Non-isolated Onboard EV Charger Controller Design Based on Port-Hamiltonian Approach(2023-01-01); The growth of the electric vehicles (EVs) market and the inadequacy of EV infrastructure, especially EV charging station, have led to an increase in charging EVs at home or the workplace. Onboard EV chargers (OBCs) have been installed on electric vehicles to charge batteries. The trend of increasing power rating and minimized sizing of OBCs, the improvement in stability and performance has been interesting. This paper demonstrates non-isolated EV onboard chargers with controller design based on Port-Hamiltonian control law to approach a robust control system and operate under wide operating range. Finally, the feasibility of the proposed control scheme is validated through experiment in laboratory. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The Development of a 1 kW Mid-Range Wireless Power Transfer Platform for Autonomous Guided Vehicle Applications Using an LCC-S Resonant Compensator(2025-06-01); ; This study presents the development, simulation, and hardware implementation of a 48 V, 1 kW mid-range wireless power transfer (WPT) platform for autonomous guided vehicle (AGV) charging in industrial applications. The system uses an LCC-S compensation topology, selected for its ability to maintain a constant output voltage and deliver high efficiency even under load variations at a typical coil distance of 15 cm. It can also operate at different distances by adjusting the compensator circuit. A proportional–integral (PI) controller is implemented for current regulation, offering a practical, low-cost solution well suited to industrial embedded systems. Compared to advanced control strategies, the PI controller provides sufficient accuracy with minimal computational demand, enabling reliable operation in real-world environments. Current adjustment can be dynamically carried out in response to real-time changes and continuously monitored based on the AGV battery’s state of charge (SOC). Simulation and experimental results validate the system’s performance, achieving over 80% efficiency and demonstrating its feasibility for scalable, robust AGV charging in Industry 4.0 Manufacturing Settings. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, EV Charging Station Planning Based on Nearby Station Data(2024-01-01); ; Thounthong, PhatiphatThis paper presents the optimal electric vehicle charging station installation planning, focusing on the installation scenarios where the location is pre-selected. The optimization process includes the maximum charging power capacity and the number of electric vehicles charging stations. Energy consumption information from nearby charging stations is harvested and then analyzed for forecasting the energy supply behavior of each charging station. This paper has a financial analysis to evaluate the cost-effectiveness of each installation scenario. Additionally, this methodology is demonstrated through the real-world data of charging patterns from electric vehicles at each charging station in Thailand. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Control Strategy of Interleaved Buck Converter for Automated Guided Vehicles with Misalignment in Wireless Power Transfer Systems(2024-01-01); ; ; Takorabet, NoureddineThe analysis of the positioning of the power transmission coil with a power rating of 3 kW and an output voltage of 48 V at a frequency of 85 kHz is presented, along with a simulation of the wireless power transfer (WPT) control system using an LCC-S resonance compensation circuit, applied to automated guided vehicles (AGVs). The case where the coil positions are misaligned with a deviation of 0-20% from the size of the power transmission coil is considered. Apparently, it can be illustrated that when the two power transmission coils are misaligned, the battery can still be charged in constant current mode using an interleaved buck converter circuit through a PI controller to increase the output power. The operation is simulated using MATLAB/Simulink software. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, State of Health Battery Estimation by Using the OCPP of Charging Station Combined with Loss of EV Charging System(2023-01-01); ; ; Thounthong, PhatiphatThe research paper focuses on estimating the health of electric vehicle batteries using electrical variables measured by the charger during the charging process. These variables are sent to a central processing system via OCPP (Open Charge Point Protocol), as the charger itself has limitations in directly measuring battery health. To overcome this limitation, this research utilizes electrical variables measured by the DC charger during the charging process to estimate battery health. The Coulomb counting method is employed in combination with an investigation into losses within the vehicle's charging system to enhance the accuracy of State of Health (SoH) estimation. The obtained battery health values will assist electric vehicle users in better trip planning and maintenance scheduling.
