How Wireless Charging Works
TECHNOLOGY OVERVIEW
From Tesla to Today
Wireless charging, also known as inductive charging, is a type of wireless power transfer that uses electromagnetic induction to either charge a battery or provide operating power. The technology was first invented by Nikola Telsa back in the late 1800s, based on based on Faraday's Law of Electromagnetic Induction.
Here’s how it works:
1. A current runs through the coiled wires of a transmitter unit
2. This generates a magnetic field.
2. The change in the magnetic field induces a current in the nearby coiled wires of the receiver unit, generating electrical energy.
The first wave of wireless chargers faced significant technical limitations that hindered their suitability for widespread industrial deployment. Notable challenges included low tolerances and the requirement for precise alignment, which posed obstacles to its real-world application.
The Xnergy Evolution
Over the past decade, Xnergy's R&D team has innovated this concept, overcoming its limitations. By identifying and syncing the coils in the receiver and transmitter units to an optimal frequency, energy transfer efficiency is greatly increased, allowing for increased tolerances.
Paired with Xnergy's industrial design focus on practicality, this results in wireless charging solutions that are reliable and ready for deployment.
Why Charge Wirelessly?
Wireless charging offers multiple key advantages over other available charging solutions today:
