| Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 101 === Contactless bidirectional charge and discharge technologies are promising technologies to be used in the vehicles which could be used to extend the usage of energy stored in the vehicle battery. As daily life of the vehicle battery is charged by the combustion engine, battery energy is mostly stayed in the saturated status. Since most energy requirement is provided by the alternator, energy stored in the battery is not fully used which causes a waste of energy. The purpose of this thesis is to develop a contactless charging and discharging system for the vehicle which is able to send the excessive battery energy to the energy storage system in the complex apartment parking lot and is able to be rechanged from the energy storage system. The idea "Many a little makes a mickle" to accumulate all vehicles’ excessive battery energy to boost the use of battery energy. To verify applicability of this energy conversion system, the simulation study has been conducted using the Protel Altium Designer 10 Software, which is used to select the components and determine related parameter values. Hardware implementation is also presented.
Keywords: contactless bidirectional charging and discharging device, magnetic energy conversion, the resonant circuit
