  无线充电技术已经成为了手机等移动设备产品脱离充电线缆的最佳解决方案,在数据交换越来越依赖WIFI环境的时代自然也需要更加便携的充电方式。然而在无线充电技术业界发展中,现在难以统一的标准乱象成为了最大的制约因素

  无线充电技术已经成为了手机等移动设备产品脱离充电线缆的最佳解决方案,在数据交换越来越依赖WIFI环境的时代自然也需要更加便携的充电方式。然而在无线充电技术业界发展中,现在难以统一的标准乱象成为了最大的制约因素

  Palm Touchstone 在 6 年前就已经实现了为移动设备无线充电的功能,当时这一技术对于移动设备而言简直是革命性的进步,人们对此议论纷纷,认为无线充电技术会成为移动设备未来发展的大趋势。然而 6 年过去了,我自己并未使用无线充电设备,也没有听说身边有人在用。分析师在当年所预测的无线充电技术将大规模推广开来的局面并未成真。无线充电行业一直在努力地想要找出一个可以适用于所有设备的通用无线充电技术标准。早在 2009 年时,Palm 就率先点燃了无线充电标准之争的战火,但是设备制造商对于能够使用无线充电技术的移动设备的研发生产却并未与之同步,想让普通消费者像日常通过 USB 端口充电那样接受无线充电技术还需要花费更长的时间。

无线充电技术如何发展? 标准将成制约因素

  在无线充电技术标准领域中,Qi 标准与 PMA 标准争斗不休,互不兼容,这使得该行业长期处于一种不确定的状态中,因为谁也不知道最终哪一种技术标准会成为未来的主流。也许到最后,这两种标准都不会成为主流。

  WPC 和 PMA 都采取了电磁感应技术,但是同样在 2012 年中,一种基于磁场共振原理名为「Rezence」的无线充电技术标准加入了角逐。Rezence 标准由 A4WP( Alliance for Wireless Power) 推出,这种无线充电技术是基于磁场共振来传输电能,而非传统的电磁感应。Rezence 标准受到了一些大公司的支持,这些公司包括了英特尔、博通、高通以及三星。Rezence 标准所代表的磁场共振充电技术能够很好地替代感应式充电,解决一些在 Qi 标准下与 PMA 标准下所无法解决的问题。

  2015 年 1 月发生了一件让业界为之震动的事件,PMA 与 A4WP 这两个无线充电技术标准联盟声明将合并,此次合并的目的就在于统一无线充电技术方面的运用标准。不过在 2015 年 6 月 30 日这两家联盟真正合并之前,事情还存在很多变数。这次合并还意味着在实践中 Rezence 标准能站在在 PMA 标准已经打下的基础上,更快更广地被 PMA 之前的成员所接纳。

  到目前为止,A4WP 已经拥有了 122 位成员,PMA 拥有 68 名成员,WPC 则是吸纳了 213 家公司会员。
