On Feb. 12, the Wireless Power Consortium (WPC) announced the release of two draft specifications to extend the capabilities of the Qi wireless power standard – “Volume II: Medium Power” to allow up to 15 Watt delivery, and “Volume III: Shared Mode” to allow multiple devices to be charged from a single transmitter. Qi-standard wireless charging is already incorporated into over 700 registered products across applications such as mobile phones and in-car charging.
These two draft specifications expand on the capabilities of Qi-standard charging, building on the basic inductive charging technology to achieve two key aims.
Firstly, the increase in power to 15W allows larger devices to be charged, such as tablets and notebook PCs – but more importantly it also allows Qi to address quick charging for mobile phones.
