Resonance Coupling

In this paper, the technologies for electric vehicle wireless charging are reviewed including the inductive coupling, magnetic resonance coupling and microwave. Among them, the magnetic resonance coupling is promising for vehicle charging mainly due to its high efficiency and relatively long transfer range. The design and configuration of the magnetic resonance coupling based wireless charging system are introduced. A basic experimental setup and a prototype electric vehicle wireless charging system are developed for experimental and research purposes. Especially the prototype system well demonstrates the idea of fast and frequent wireless charging of supercapacitor electric vehicles using magnetic resonance coupling. Though the idea of wireless energy transfer looks sophisticated, it is proved to be a handy technology from the work described in the paper. However, both component and system-level optimization are still very challenging. Intensive investigations and research are expected in this aspect.

Our world is running out of fossil fuel so people start to change themselves and started to use an electric vehicle. In electric vehicles the charging is a big deal, this project includes solar and wind energy charging mechanism to generate power for electric vehicle both day and night. And it contains Raspberry pi that is programmed to calculate the amount of power charged for an electric vehicle, then the user can know that the information via Blynk application. The power generated by solar panel setup is given to the battery via DC-DC converter because the power from solar panel setup is a variable DC, so that is converted into pure DC. And the power generated by wind generator setup is given to battery via AC – DC converter, the power from a wind generator is AC, so that is converted into DC.

Vehicle Charging

Smart grids incorporating internet-of-things are emerging solutions to provide a reliable, sustainable and efficient electricity supply, and electric vehicle drivers can access efficient charging services in the smart grid. However, traditional electric vehicle charging systems are vulnerable to distributed denial of service and privileged insider attacks when the central charging server is attacked. The blockchain-based charging systems have been proposed to resolve these problems. In 2018, Huang et al. proposed the electric vehicle charging system using lightning network and smart contract. However, their system has an inefficient charging mechanism and does not guarantee security of key. We propose a secure charging system for electric vehicles based on blockchain to resolve these security flaws. Our charging system ensures the security of key, secure mutual authentication, anonymity, and perfect forward secrecy, and also provides efficient charging. We demonstrate that our proposed system provides secure mutual authentication using Burrows–Abadi–Needham logic and prevents replay and man-in-the-middle attacks using automated validation of internet security protocols and applications simulation tool. Furthermore, we compare computation and communication costs with previous schemes. Therefore, the proposed charging system efficiently applies to practical charging systems for electric vehicles.

In order to inductively charge electric vehicles, which are based on a low-voltage drive train, high currents have to be overcome. This work describes a simulative approach to charge 48 V-based electric vehicles wirelessly with high power. A system was designed on the basis of various boundary conditions and validated by simulation. In order to increase the transmittable power, the system was investigated for an extendable approach and was examined for modularity. In particular, the influences of the secondary coils on each other must be taken into account. Finally, the entire system was evaluated by physical and electrical simulation.

Abstract Climate change is a growing concern due to greenhouse gas emission and transportation has increased the requirement for various energy sources with limiting and less pollution. But with the establishment of more electric vehicles on the road, charging EV’s will be difficult if the grid is used. When many numbers of electric vehicles are integrated to the grid, it will inevitably have a huge effect on its function and control. Hence, there is a requirement for an effective charging system for electric vehicles using renewable energy sources. Solar energy is renewable and green, but the volatile nature of energy from the Photo-Voltaic (PV) system and dynamic charging requirement of electric vehicles has added new problems to the effective charging of EV from these sources. The Solar powered charging station with battery storage system is a better solution for this problem. The power is transferred from the AC grid to the DC link when there is a depletion of power from solar. This paper deals with DC level 1 fast charger to charge an electric vehicle with phase shifted full bridge converter as a main charging topology which is able to deliver the load of 50KW to charge the electric vehicle. To maintain a constant voltage at the output of the boost converter connected to the solar panel, a fuzzy controller is also developed in the proposed system

Charging System

Wind energy conversion system fed EV battery charging system using single phase bridgeless cuk converter is proposed in this paper. PMSG is employed in the WECS to convert the mechanical energy into electrical ac power. In standalone wind energy conversion systems, two stage ac-dc & dc-dc converters are employed to obtain the desired output. The bridgeless cuk converter employed in the proposed charger is a single stage converter which acts as rectifier as well as dc-dc converter. The bridgeless cuk converter converts the ac voltage generated from PMSG into a desired dc voltage for charging the battery of an electric vehicle. Thus, an intermediate stage of power conversion is reduced in the proposed system. Also, a simple output voltage controller is employed in the proposed system to charge the electric vehicle battery with constant voltage irrespective of the wind speed. The proposed off-board EV battery charger is simulated in Simulink environment of MATLAB software and the results obtained are furnished in this paper. The experimental investigation has been carried out in the developed laboratory prototype of the EV battery charging system and the obtained results are furnished in this paper.
