碩士 === 國立成功大學 === 電機工程學系碩博士班 === 100 === The purpose of this thesis is to design and implement an efficiency contactless inductive charging paddle. This thesis is aimed at the recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773). The high-efficiency inductive charging system is proposed for providing the EV users with high security and convenience. Charging paddle and charging receptacle are formed by three-phase inductive coupled structure, so as to improve the core’s utility； both structures adopt position matching method and the air gap 3mm specification to design the system circuit parameter. This electric vehicle’s charging paddle system has proven to be practicable by experiments. The transmission efficiency can reach a maximum of 81 % under 3 mm air-gap.
