该联盟的无线电源和电源事务联盟本周强强联手，这将有助于硬件制造商看中他们的设备无线充电标准。
The协议周二宣布that allows two of the three major wireless-charging consortiums to share their specifications means there's one less obstacle in the way of a wary mobile device industry looking to adopt the technology.
On its face, the merger between the Alliance for Wireless Power (A4WP) and the Power Matters Alliance (PMA) should allow them to create a consistent wireless charging experience for consumers with enabled devices.
这意味着消费者将不再需要他们的智能手机或平板电脑附着在A4WP的Rezence或PMA的Powermat的规格是否当他们将其拖放到星巴克的无线充电点担心，麦当劳或者在启用商店。

However, the partnership between two specification groups still leaves a horse race, with the winner determining which wireless charging technology will cross the finish line.
Like the Blu-Ray Disc and HD DVD standards (and Betamax and VHS before that), one wireless charging specification will eventually win out. Which one does will be decided by device manufacturers, not industry groups.
但是，伙伴关系已经聚集A4WP的磁共振（松散耦合）充电和PMA的电感（紧密耦合）充电。基本上，共振允许多个设备充电一次在任何结构的垫。感应式充电需要启用的设备更精确地放置在一个垫之前，将收取。

该A4WP已经有两个感应和共振充电作为Rezence规范的一部分。但是，领带，两个对手之间也加强了他们对旧的和更大的挑战者 - 无线充电联盟（WPC）。在WPC拥有广泛采用齐规格，它是基于感应式无线充电，但集团也表现出做共振充电在今年的CES展上的附加功能。
The Qi specification, which also includes resonance and inductive technology, is supported by200 companies, among them a veritable who's who of electronics, including LG Electronics, Sony, Nokia and Verizon Wireless. "Qi has been dominant and is way ahead of the game," said William Stofega, a program director at research firm IDC.
There are now more than 400 Qi-enabled devices today, including mobile phones, such as the Samsung Galaxy S4 and S3, Nokia Lumia 1020, LG G2, Motorola Droid Maxx and Mini and the Google Nexus 5 phone and Nexus 7 tablet.
“几乎所有的东西[无线充电启用]按时发货去年是符合木塑规范，”瑞恩桑德森研究公司IHS副主任电源和存储组件说。
Even so, the WPC will undoubtedly be concerned about the alliance between the PMA and the A4WP, "just because of their market share," Sanderson added.
移动设备制造商，如三星电子和LG电子，看到无线充电作为一个加号，因为消费者可能会在一个更喜欢用手机无线充电没有。
正在进行整合
无线充电行业内的整合是不是新的。去年，金霸王的Powermat的技术子公司宣布合并凭借其欧洲同行，PowerKiss，在带了两个不同的无线电源规格一起在一把伞下的交易。这两家公司都属于PMA联盟下。
PMA由Powermat的，它在美国在欧洲拥有1500个多点的充电要求其出生，PowerKiss表示，在机场，酒店以及一些麦当劳餐厅1000个充电点。
So for the A4WP, which already had both resonant and inductive wireless charging in its specification, the partnership is more about increasing its customer base as well as adding smart technology.
The PMA's specification includes an API that monitors the power that's transmitted, and can manage pre-specified policies, such as how much power any device requires before it's fully charged.
丹尼尔·施赖伯，Powermat的总裁和PMA的董事会成员，他说的Powermat的感应技术比共振充电效率更高，使得它最好的一样，不希望浪费功率咖啡店的地方。
Consumers also may be more nervous about having their mobile devices charge next to a stranger's, Schreiber said, making inductive charging's single device limitation more attractive.
"They're highly complimentary implementations, much like WiFi and 4G," Schreiber said, referring to magnetic induction and resonant charging. "They're not displacing each other, but complimentary to one anther."
并非所有人都同意。
The end game will be resonance-only wireless charging with machine-to-machine data transfer, according to Reinier van der Lee, director of product marketing at Broadcom. "We always felt resonant technology was the way to go, but we also feel the [PMA's] inductive install base needs to be offered a transition path to resonant charging," van der Lee said.

Broadcom公司是A4WP成员，计划在今年晚些时候，将包括无线电源管理功能推出的芯片组。德州仪器已经使无线充电芯片组。
约翰Perzow，市场开发的WPC的副总裁说，对手组织实现自身的产品不能满足整个市场后会师。但PMA和A4WP将不得不做出重大权衡他们的技术之间实现互操作性。
"For instance, you can always shoehorn two technologies in one phone, a so-called 'dual-mode' approach. But this increases cost and complexity and typically requires tradeoffs like lower efficiency," Perzow said.
IHS的桑德森是希望所有三个无线电力财团最终能够在通用标准一起工作。在此之前，手机，平板电脑和其他电子设备制造商将保持谨慎关于如何选择一个技术比另一种可怕的，他们会做出错误的选择。
Perzow said the WPC is in talks with the PMA and the A4WP.
“但我们要清楚，”他说。“什么PMA和A4WP宣布没有一个合并后的集团，他们都被填充技术，对方并未有差距，” Perzow说。
“当你买气，你知道它会与任何技术和功能发展的道路的工作，”他继续说。“保持这种兼容性是首要目标，我们非常感兴趣，并渴望与人合作，共享这一目标，包括PMA和A4WP”。
