I. Examples of Haitong Wireless Charging Coil Design Schemes
Coil design scheme for wireless charging of electric vehicles
Haitong's wireless electric vehicle charging uses a three-coil design to meet different charging needs while improving charging efficiency. The vehicle-side main coil is responsible for transmitting energy, and the terminal consumer electronics coil is responsible for receiving energy. Energy transfer is achieved through inductive coupling between the two.

II. Advantages of Haitong Communications' Wireless Charging Technology
① Ultra-thin and high efficiency
Some of Haitong Communications' wireless charging coil solutions use multi-strand fine wire technology. Compared with single-strand flat wire, multi-strand fine wire has the advantages of high Q value and higher efficiency, and the overall cost is advantageous, but the process is more difficult. Currently, Haitong has been using multi-strand fine wire PIN with thermal compression welding technology to weld FPC to replace the existing FPC double-layer copper-plated coil design. This can reduce energy loss and thickness while ensuring charging efficiency, and improve product charging efficiency.
Advantages: Ultra-thin, high power - multi-strand wire winding
② Advanced R&D equipment configuration
Haitong Communications' wireless charging coils use high-quality coil and conductive materials. R&D personnel have solved many technical problems, expanding product applications, which can improve charging distance, enable charging even with metal foreign objects, enable wireless charging of computers, and enable simultaneous charging of multiple terminal devices, providing users with a convenient "put-and-charge" charging experience. 。
