The Secret of Wireless Phone Charging How Does the Charging Process Without a Cable Ribet

YOGYAKARTA - Many users are now starting to switch to wireless technology, but often there are questions about how the wireless charging process is carried out safely on daily devices.

This technology actually utilizes a physics principle that allows energy to move through the air. Well, by understanding the mechanism, you can maximize this feature and maintain the health of your smartphone battery in the long run.

What is Wireless Charging Technology?

Reported by VOI from the FreePower (FKA Aira) website, wireless charging or wireless charging is a method of charging the battery without having to plug a physical cable into the phone port.

This technology relies on energy transfer through magnetic fields. If you've ever seen an electric toothbrush that is charged just by being placed on its stand, that's the early form of induction technology that is now adopted by smartphones.

Wireless Charging Handphone How is the Charging Process?

To answer the question about how wireless charging works, you have to look inside the device's components. This process involves two copper wire coils, namely:

Transmitter Coil

Located inside the charging pad. When this device is connected to the electricity, the current will flow through the coil and create a magnetic field around it.

Receiver Coil

It is located at the back inside your phone. When the phone is placed on the pad, the magnetic field from the transmitter will capture this receiver coil.

Well, the magnetic field then produces an electric current back inside the coil of the cell phone, which is then converted into chemical energy to charge the battery.

Knowing the Qi Standard, Why Is It Important?

In the world of wireless charging, there is a term "Qi" (pronounced: chee). This is a global standard set by the Wireless Power Consortium (WPC).

The existence of this standard ensures that Samsung, iPhone, or other brand phones can use the same charger without compatibility problems. Just like USB or Bluetooth, the Qi standard guarantees uniform safety and energy efficiency around the world.

Brief History and Evolution

Although it feels very futuristic, who would have thought that the foundation of this technology was actually laid by Nikola Tesla in the late 1800s, alias more than 100 years ago!

However, the commercial use of this technology only exploded in 2012-2013 when technology giants such as Samsung began integrating it into their flagship products.

Now, wireless charging is not only at home, but also in cafes, cars, and airports.

Advantages and Safety of Wireless Charging

Apart from the practicality factor because there is no need to disassemble and assemble cables, this technology has smart security features.

If the battery is full or the phone is too hot, the charger will automatically reduce the current flow or stop it.

In addition, there is a foreign object detection feature that prevents the device from sending electricity if there are other metal objects (such as keys or coins) on the pad.

Understanding wireless phone charging how the charging process helps us realize how efficient the interaction between magnets and electricity is in making human life easier. Although charging cables are still faster for now, the convenience offered by wireless charging is clearly a future that is hard to refuse.
