Qi-certified products reach 100

The Wireless Power Consortium (WPC) has revealed that the 100th Qi-compliant product had been listed on 16th July. The milestone for the wireless power technology is a Qi transmitter developed by Convenient Power Hong Kong, one of the founding members of WPC, and was tested for compliance at TUV Rheinland.

Qi compliance testing was first offered by Philips in the Netherlands. TUV Rheinland later took over this service, becoming the first officially appointed Qi test lab in August 2011. Since the launch of TUV Rheinland Qi testing service, the number of certified Qi products worldwide has more than doubled, from 45 to 109.

In addition to TUV Rheinland's verification of the Qi compliance of products, it also hosted the 23rd WPC member meeting in Taipei. During this meeting the latest test specification, version 1.1, was adopted. This new test specification will improve reliability and ease of use for Qi devices by adopting so-called Foreign Object Detection. This will prevent a charging station from charging a mobile device when a foreign object is present on the charging surface. A foreign object can be anything from a coin to a key, a chewing-gum wrapper, or something similar. It is essential that such objects are detected, both to prevent overheating and damage to equipment and to prevent burns when removing these objects or devices from the pad after charging has been initiated.

The future of the Qi standard is the spread of usage from the current low-powered devices to medium-powered devices such as tablets, notebooks, etc. A design standard for such medium-powered devices is expected to be available sometime in 2013. There will also eventually be a standard that covers such high-powered devices as kitchen appliances, though this is not expected before 2015. Many challenges lie ahead for WPC members, but with their combined force we are sure products made according to the Qi standard will become mainstream in our daily lives and elsewhere.

TUV Rheinland is very proud that they are contributing to this new technology. Notably, TUV Rheinland will be the first to offer testing services according to the latest standard version, starting at the end of September 2012. TUV Rheinland will continue to support the members of the consortium with the service and expertise, to ensure them to enter the market successfully.
