特斯拉的开创性实验为
谐振和感应无线充电方法铺平了道路。
无线充电联盟 (WPC) 是 2008 年成立的科技行业领袖团体,目前包括 Apple、Samsung、Nokia、Sony、贝尔金等重量级合作伙伴。其目标是创建一个通用的无线充电标准,以兼容从智能手机到可穿戴设备等各种设备。WPC 支持 Qi(发音为 chee)无线充电标准。
Qi 源自中文单词“气 qi”;繁体中文:氣,意为生命能量。自推出以来,Qi 标准经历了多次迭代,提高了效率并缩短了充电时间。获得 Qi 认证表明设备的功能性和操作安全性得到了认可。随着该技术的发展,在采用 Qi 充电标准设计配件方面,贝尔金一直走在前列。

Qi2 的强大功能之一是支持更高功率传输的“远场”充电,可提供高达 100 瓦的功率。这允许同时为多个设备充电,并为笔记本电脑和平板电脑等能耗更大的电子设备供电。不过,100 瓦的功率尚无法用于对智能手机进行无线充电。另一项关键改进是“中场”充电技术的推出,该技术无需充电器和设备直接接触,即可实现高达 15 瓦的充电功率。此应用非常适合耳机和智能手表等往往配有小型充电板的设备。
其他增强功能包括更快的充电速度、更高的效率以及提升的通用兼容性。一旦其他设备采用 Qi2 标准,就会实现真正的通用兼容性,此列表汇编了当前的兼容设备。通用兼容性将消除对单独充电器的需求,并确保用户可以使用同一个充电板或支架为多个设备充电,而无需担心标准和协议。通过优化电力传输,Qi2 提高了效率,使设备能够快速充电而不影响能耗。该技术的未来主义设计在速度、便利性和效率方面超越了前代。
*基于内部测试。与 Qi 5 瓦无线充电器相比,贝尔金 Qi2 15 瓦无线充电器将 iPhone 15 的电量从 0 充至 50% 的速度要快 2 倍,与 Qi 7.5 瓦无线充电器相比则要快 1.5 倍。充电时间因环境因素而异;实际结果会有所不同。
