摘要
传统的有线式充电方式由于存在数据线的束缚以及充电口的频繁插拔不仅牺牲了用户便捷的充电体验还带来安全隐患。通过无线充电技术减少了插拔的麻烦,同时亦避免了接口不适用,接触不良等现象,提高了手机充电的便携性、安全性以及兼容性。文章从手机无线充电原理、无线充电系统结构以及外部因素对无线充电传输效率的影响等方面进行研究。
The traditional wired charging mode not only sacrifices the user’s convenient charging experience, but also brings security risks due to the binding of data lines and the frequent plugging and unplugging of charging ports. Through wireless charging technology, the trouble of plug-in and plug-in is reduced, and the phenomenon of unsuitable interface and poor contact is avoided, so the portability, safety and compatibility of mobile phone charging are improved. This paper studies the wireless charging principle, the structure of wireless charging system and the influence of external factors on wireless charging transmission efficiency.
