Abstract:
Recently， there has been a huge increase in the usage of fuel resources for automobiles which is severely affecting the climate and causing global warming. The use of electric vehicle （EV） is an effective way to protect the environment and reduce travel costs. However， the EV charging system has a single charging source， and the charging rate is limited. In this paper， an EV wireless charging system based on dual source power supply has been developed. It realizes intelligent switching between 12 V photovoltaic output and 220 V AC dual source power， and has wireless transmission function. Based on the proposed power supply architecture， the micro wireless charging model is built， which enables the EV model to store power and realize static and mobile control through the wireless induction charging system.
