WHAT IS WIRELESS CHARGING 9 Wireless charging uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. By simply placing a smartphone on a special mat or tabletop, consumers can enjoy simple and effective charging without any hassle. Develop safety and protection systems in hardware and software to protect the equipment and operating people in the case of a fault or if an over-voltage, over-current, short- circuit, or over-temperature event occurs. Wireless charging can be of different types: Wireless car charging is an enhanced version of smartphone charging with several differences. This paper presents a novel multi-objective optimization model framework based on life cycle assessment (LCA) for siting wireless chargers in a multi-route electric bus system. Low-power Direct Current charging stations (15-45 kW, supporting bi-directional energy flow up to 11 kW) for passenger vehicles and motorcycles. The main objective behind wireless tech is to offer greater mobility and convenience. 2. This system demonstrates the concept of wireless mobile charging system . The power is transferred from a source to an electrical load without the need of interconnections. The transmitter circuit consists of DC source, oscillator circuit and a transmitter coil. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. TESTING/ RESULTS Voltage Regulator (LM7805C) is used to have an output of 5 V. Input using function generator. WPT is useful to power electrical devices where physical wiring is not possible or inconvenient.. People often compare the wireless transmission of electrical energy as being similar to the wireless transmission of information, for example, radio, cell phones, or wi-fi internet. For this, you just need to have a compatible charger and a compatible device. Overall Objective: Analyze, design, build, and validate a vehicle integrated high power and dynamic wireless electric vehicle (EV) charging system which is viable when applied to real world traffic conditions in the U.S. Study and analyze existing state-of-the-art (SOA) dynamic wireless EV charging systems to identify Research and report on cost savings potential of production run rates of system components. Secondly, wireless charging uses more energy and is less efficient. When the two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy with each other. Enhanced information to users, before, during and after charging. Although wireless electricity transmission can in theory work over long distances (as proposed by . Then, the conclusions are given in the last section. The system allows user to wirelessly charge his mobile phone without plugging in the mobile adapter. Wireless electricity is quite literally the transmission of electrical energy without wires. Wireless charging eliminates the cable typically required to charge mobile phones, cordless appliances and so on. The first circuit is transmitter circuit used to produce voltage wirelessly. The wireless architecture is designed to minimize fields outside the vehicle footprint, which reduces the risk of exposure to humans. Optimal siting of wireless charging bus stops is key to reducing these burdens and enhancing the sustainability performance of a wireless charging bus fleet. The main purpose of wireless charging is to connect with the object to charge or recharge the battery of any devices such as smartphones. The patent uses electromagnetic induction technology. Recently, the wireless charging. 15. The patent uses electromagnetic induction technology. When the DC power is given to the oscillator . It's pretty obvious that the true purpose of wireless charging is to eliminate the need for wires and cables. This allows for the transmission of electricity without wires or cables by creating a magnetic field between two electrical circuits: the transmitter and receiver. 10. The advantages include the no hassle of carrying wires, easy charging, and smoot of power transmission even in unfavorable environmental circumstances. In wireless charging there are transmitter and receiver, 220V 50Hz AC supply is converted into High frequency alternating current and this high frequency AC is supplied to transmitter coil, then it creates alternating magnetic field that cuts the receiver coil and causes the production of AC power output in receiver coil. Abstract and Figures Wireless charging is a technique of transmitting power through an air gap to an electrical device for the purpose of energy replenishment. There is no cable to plug in, and although wireless charging used to always take much. Wireless power transfer is a generic term for a number of different technologies for transmitting energy by means of electromagnetic fields. WPT is an attractive solution for many industrial applications due to its enormous benefits over wired connections. Transferring electrical power to a portable product by placing it in a cradle or on a flat charging surface. Principles of wireless charging technology 2.Magnetic field resonance It is composed of an energy transmitting device and an energy receiving device. TYPICAL WIRELESS CONVERSION- CHAIN 10 11. Updated on February 23, 2019. Safety is incorporated in the ancillary systems covering foreign object detection (FOD) and living object protection (LOP). The major difference is that with radio . Download Project Document/Synopsis. Michael Lipphardt Wireless charging is made possible by the principle of 'magnetic resonant coupling'. Along with WPT, the benefits of Photovoltaic (PV) array are exploited and a system is proposed for extracting the power from PV array to charge the Stochastic Systems Modeling for Wireless Charging Electric Vehicle free download [The Route to Wireless Charging of EVs] With a wireless charger, the battery inside any battery-powered appliance can be charged by simply placing the appliance close to a wireless power transmitter or a designated charging station. The electric current of the magnetic field works to charge the device or any other object. "Wireless charging" is the process of electrically charging battery-powered devices and equipment without the need for a wired electrical power connection. In our Wireless battery charger, we use two circuits. Rough math suggests wireless chargers need almost 50 percent more energy to fully charge up a phone, but this varies between . The fourth section shows and discusses the simulation findings, and the experimental results. Vpp = 7 V Frequency = 110 KHz wave type: sine Output readings: Voltage = 4.9 V Current = 0.7 A Add pictures of breadboard, multimeter, function generator, and phone when it is being charged. 1.3 Objectives The objectives of this project is: To study and investigate on wireless power transfer.
