Power transfer is a promising new technology Wireless charging networks are being deployed for a RES array, which will be used in electric vehicles, industrial automation, and biomedical implants. Yet, due to power losses, electromagnetic interference, as well as the potential of unauthorized access or malicious attacks, guaranteeing the reliability and security of WPT systems is still a big challenge. Conventional monitoring and defect detection mechanisms need to be more efficient, reactive in real-time, and prone to data tampering. Implementation of the blockchain is a promising usable solution to solve these issues due to decentralized, tamper-proofed and transparent data management characteristics of the technology. At the same time, the research presents results on the implementation of one of the blockchain-oriented technologies in terms of constant control of normal operating conditions and detection of defects in wireless power transfer (WPT) networks, thus improving the efficiency of the operation while ensuring the security of the entire system. This study presents a novel data integrity assurance and autonomous fault detection framework for WPT systems by integrating blockchain with real-time sensor networks and artificial intelligence (AI)-based analytics. Automated Responses: Smart contracts allow automatic reactions when anomalies are detected, minimizing downtime and maintenance costs. Moreover, it enables secure and transparent records of power transactions using distributed ledger technology (DLT), preventing unauthorized access to energy and enhancing accountability of the system. Results of simulation and experimental validation show the gain in defect detection accuracy, reduced fault reporting latency, and improved cyber-attack resilience of blockchain-enabled WPT networks. This research proposes a pioneering model that can utilize blockchain-based monitoring solutions to enhance the design of WPT networks, providing an innovative proof of concept that can address the limitations of such systems. In the future, research directions that address challenges such as optimizing consensus mechanisms specifically for low-power IoT devices and investigate hybrid blockchain models could improve scalability and increase transaction speed to facilitate potential real-world applications of WPT in practical cases.

Electric vehicles (EVs) are getting more importance than traditional vehicles in today's era as they may lead to significant changes in society, so more research needs to be done on electric cars for their expansion. In most EV architecture, the charging station plays an important role. Due to the growth of the extended travel range of EVs, these will travel over different networks that different utility providers might serve. To mitigate this issue, we propose a solution based on the uniform Token generation concept. The concept of blockchain technology will be utilized for Token generation, as the blockchain technique is transparent and traceable; it does not require any third party for its operation. The proposed model will get information about the battery level of each EV through a communication network and based on the battery level. The corresponding best charging station will be assigned. When the EV starts to charge from the given charging station, a certain amount of tokens is transferred from the customer's wallet to that charging station's wallet.

Recent advances on wireless energy transfer (WET) make it a promising\nsolution for powering future Internet of Things (IoT) devices enabled by the\nupcoming sixth generation (6G) era. The main architectures, challenges and\ntechniques for efficient and scalable wireless powering are overviewed in this\npaper. Candidates enablers such as energy beamforming (EB), distributed antenna\nsystems (DAS), advances on devices' hardware and programmable medium, new\nspectrum opportunities, resource scheduling and distributed ledger technology\nare outlined. Special emphasis is placed on discussing the suitability of\nchannel state information (CSI)-limited/free strategies when powering\nsimultaneously a massive number of devices. The benefits from combining DAS and\nEB, and from using average CSI whenever available, are numerically illustrated.\nThe pros and cons of the state-of-the-art CSI-free WET techniques in ultra-low\npower setups are thoroughly revised, and some possible future enhancements are\noutlined. Finally, key research directions towards realizing WET-enabled\nmassive IoT networks in the 6G era are identified and discussed in detail.\n

In a recent work the author presented a hybrid control scheme for series resonant inverters owning a number of nice properties. In the present work several refinements and bounds on the allowable parameters are obtained yielding a more precise methodology to design the hybrid control scheme presented in the previos work. In particular we define the permissible range of loads and controller gains, we present a complete proof for asymptotic stability when the hybrid control strategy is used and we ensure that no catastrophic failure occurs when a zero resistance is used as load. Another important new feature in this note is that results do not require the exact knowledge of any of the plant parameters.
