การออกแบบและทดสอบเทคโนโลยีการอัดประจุยานยนต์ไฟฟ้าแบบไร้สายตามมาตรฐานสากล

To achieve low carbon society goal, according to Thailand 4.0 policy, the use of conventional internal combustion engine vehicles (ICEVs) should be replaced with the electric vehicles (EVs). Since it releases zero tailpipe pollution, the EVs is environmentally friendly. It is more energy efficient compared with the ICEVs. Moreover, the running and maintenance cost are much lower. The main charging solutions for EVs are conductive (wired) and wireless battery charger. The heavy cable and bulky mechanical plug are needed in the conductive charger. In contrast, wireless charger requires no physical contact which provides safety (from electric shock or spark) and convenient to the user. Furthermore, it is weatherproof, and can be used in hostile environment. However, international standard such as IEC 61980 Electric vehicle wireless power transfer (WPT) systems, ISO 19363 Electrically propelled road vehicles - Magnetic field wireless power transfer - Safety and interoperability requirements, and SAE J2954 Wireless Power Transfer for Light-Duty Plug-In/Electric Vehicles and Alignment Methodology must be taken into consideration while designing and testing the EV wireless charger. Thus, this researh focuses on the design and testing of the wireless charging technology for electric vehicles according to international standard.
