Wireless charging Way of working

Latest company news about Wireless charging Way of working

Electromagnetic induction

This is the most common way that wireless chargers work. It uses the principle of electromagnetic induction to generate current through electromagnetic induction between the primary and secondary coils, thereby realizing the transfer of energy within the space. This wireless charger's The implementation method has been promoted by the Wireless Charging Alliance. 
radio waves
Radio waves are a relatively mature wireless charging method for wireless chargers at this stage. Its working principle is to use miniature and efficient receiving circuits to capture radio waves in space, and then convert electromagnetic energy into stable electrical energy. There are already companies claiming to be able to wirelessly charge electronic devices smaller than a cellular phone from a few meters away. 


electromagnetic resonance

This is a wireless charging technology that is still in the research and development stage. This technology is mainly researched by a team led by a physics professor at the Massachusetts Institute of Technology. Intel engineers use this technology as a basis to achieve a power supply that is about 1 meter away from the power source. A 60-watt light bulb lights up about 10 feet away and has a transmission efficiency of 75%. Intel engineers say the next goal will be to use this wireless charging technology to charge modified laptops. However, in order to achieve this goal, it is also necessary to solve the interference and impact of electromagnetic fields on other components in the computer.
