Design Of Contactless Power Transfer System For Lithium-ion Batteries

Contactless power transfer is a new way to transfer energy,it can develop out the contactless charging equipment in different directions and different places,it can get rid of the restriction of the traditional cables,has a promising prospect.It's development makes the grown-up and perfection of this kind of equipment.On the basis of what introduced the current studying situation of contactless power transfer technology,Analyze the lithium-ion battery's electrical characteristic and the battery charging pattern and the security issue.In particular,analyze and design the circuit of the power sending and power receiving,lithium-ion battery pack and the charge management IC.It realized the purpose that the medium and small sized power equipment for wireless power supply. It provides a wireless power technology example for application of design of contactless charging platform in portable electronics products.Finally,summarizing main works of the thesis,clarifying the value and significance of this research.
