How does wireless charging work?

Inductive charging

The underlying principle of inductive charging

Wireless charging works on the basis of induction. That’s why it is called “inductive charging” or “wireless charging.” For example, you probably have already used inductive charging to recharge your electric toothbrush, since this device works on the basis of the same principle.

The smartphone and the charging station (e.g., INBAY) communicate with each other over the Qi-Standard. The underlying principle is called “resonant inductive coupling,” which takes place between the transmitter (charging station) and receiver (smartphone).

The charging station (in our case, INBAY) constantly checks whether a Qi-compatible device is in contact with the charging station. If the charging station detects a Qi-compatible device whose battery needs to be charged, the charging process will start automatically. The charging station and the receiver in the cell phone exchange data about the progress of the charging process, and the charging station switches to standby mode as soon as the battery is fully charged.

The charging process is therefore only initiated when it is needed and a Qi-compatible device with a less than fully charged battery is placed on the station. There is nothing more to think about, and you can simply leave the device on the charging station, because thanks to the Qi standard, the entire process takes place completely automatically.
