Wireless charging is the process of transferring power with electromagnetic fields. As the name suggests, wireless charging transfers power without any physical, wired connection. Check out a brief demo board that we developed to demonstrate this technology:
Wireless charging, better known as inductive charging, requires the two devices (the charger plate and the device) to have coils that can use inductive coupling to charge the battery on the device. Inductive charging creates an alternating electromagnetic field that allows power to be stored in the device's battery. The proximity of the charger plate and device are very important because faster charging occurs with closer distances. With time, the distances should increase (along with technology) and eventually, every device we own may be in a wireless charging field that will allow for unlimited battery life. However, there are many obstacles in the way of this happening including regulations to health and well-being, power requirements needed to have such large electromagnetic fields, and lastly, every device would need to have the capability to connect to this new type of “network.”
Although this idea of endless battery life via wireless charging is very appealing, it is a very distant reality. The current market landscape that will incorporate wireless charging requires a large power requirement to transmit the power over space. As technology progresses, the distance that power can be transferred is growing larger and larger with power requirements continuing to decrease.
There are many companies that are innovating and pioneering into an industry that is fairly untraveled. We are looking forward to what’s next, and we are excited to see that there are companies who see this new technology as the way of the future.
