Abstract:Aiming at the problem of low charging efficiency and poor controllability of charging power in most wireless charging systems at present, a new intelligent wireless charging system is designed. The system is embedded in the battery module, the power acquisition module, the low-power master chip and the 2.4G communication module. The charging module is embedded with the same main control and communication module. The charging module can receive the real-time voltage and charging current information of the battery through 2.4G wireless communication. According to the built-in intelligent algorithm, the adaptive dynamic output can be realized by amplitude modulation carrier power limitation. Experiments show that the system has high charging efficiency within the effective distance, and the specific charging can be intelligently controlled according to the real-time battery information, which effectively prevents battery overcharge and over discharge. The intelligent wireless charging system has the characteristics of low power consumption, high conversion efficiency and intelligent management of charge and discharge. It can be widely applied in smart home, intelligent medical treatment, smart wear and other fields, and has good social and economic value.
