The development of electric vehicles based on electric motors has stolen international attention since the beginning of the 21st century. Electric motor-based vehicles are considered the future of transportation technology because they have high efficiency values and also technology without exhaust gas or zero emission. EV1 Electric vehicles still rely on Lithium-ion battery-based electric power storage technology that has a low power storage capacity and requires considerable time in charging. Based on the transfer media, recharging the battery is divided into two methods, namely using cable and wireless. For the method of recharging electric vehicle batteries using cables, they still have some weaknesses, including: physical dangers of cables for users, security issues in wet / damp charging conditions, and the danger of electric shock. The most appropriate solution to answer some of these weaknesses is the use of wireless power transfers with inductive power transfer methods. In the real world, further development is needed to consistently produce efficient wireless electric car battery charging, efficiency changes caused by inconsistencies / misalignment between the primary coil and the secondary coil must be examined. In addition, to continue the previous research, a study was conducted to see the alignment relationship between the primary coil and the secondary coil with the coupling coefficient, as well as the relationship between the water gap and the coupling coefficient. 3D modeling is done using the method of Finite Element Method (FEM) with JMAG software.
