Qi Wireless Charging

Qi – the Chinese term for ‘energy flow’, pronounced as ‘chee’ in ‘cheese’ is the widespread standard for wireless charging of the battery operated gadgets such as mobile phones, iPods, Mp3’s and cameras. With this particular technology the electromagnetic coils that send out and receive the charge are specifically safeguarded to lessen electromagnetic rays.

 

Electromagnetic Induction – Basic Principle of Qi Wireless Charging

The wireless power transfer happens via electromagnetic induction. With the inductive charging the necessary power gets to the device not through the conventional cable but instead wirelessly with the use of electromagnetic fields.

Wireless Charging is not a real brand-new technology. Electric tooth brushes have used the concepts of inductive charging for several years. Qi Wireless Charging runs on the resonant inductive combining between sender i.e., the charging station and the recipient i.e., the mobile device. A normal test “ping” signal is sent by the charger to check  for devices and a ping is sent back, informing the Qi enabled charger platform that a Qi appropriate cell phone exists. The charger inspects the phone to see if it is compatible to the Qi standard. As soon as Qi compatibility and the power speed is determined, the induction charging starts. While charging the charger and phone stay in contact and will automatically go into standby mode as soon as the battery is completely charged.

 

Advantages of Qi Wireless Charging

The most significant benefit of Qi Wireless Charging technology is that cellular phones and battery chargers from various manufactures are suitable. The solely requirement is which both the parts – the sender and the receiver – complete the Qi requirements. Hence, each Qi enabled gadgets are suitable with every single Qi charging transmitter, irrespective of the producer or make of the device. The amount of enabled devices is continuously increasing as Qi wireless charging technologies are incorporated by an ever growing list of makers. This enables us to charge the numerous battery operated electronic digital devices with merely a single charging station.

Qi chargers are also energy efficient and only trigger and exchange energy when an enabled device requesting charging is positioned near the charger.

 

Is my phone compatible?

There is a growing number of phone available that support Qi, the latest Samsung and Xiaomi phones have this built in.
