An Intelligent Wireless Charger Based on the Internet of Things

With the development of the times and the progress of science and technology, people continue to explore new possibilities; the leap from wired to wireless is one of them, breaking the limitations. Similar to wireless mice and wireless microphones, this paper aims to study an Internet of Things-based smart wireless charger that, by using mathematical analysis and wireless charging technology, requires experiments to include wireless charging stations, associated chip areas, and home gateways that are used in combination with them. In the experiment, the control circuit, transmit circuit, and reception circuit of wireless charger are studied, and the wireless charging system is analyzed and calculated in detail, and a wireless charger is designed. Electromagnetic field sensing, radio wave transmission, and resonance methods are applied to achieve the shortest charging time and the best quality in order to prevent the charger from heating and burning during charging. Experimental data show that this Internet of Things-based smart wireless charger can fully replace wired chargers for 99% of small appliances; the charging efficiency of large electrical appliances such as desktop computer is also 1.4 to 1.6 times increased. Experimental data show that this Internet of Things-based smart wireless charger can efficiently and conveniently charge electrical appliances; however it is relatively expensive; the required technology is relatively complex but can make charging more efficient. It can be seen that wireless charging has a major breakthrough in the concept of future charging.
