Скачать или смотреть IInvenTiv-2024 ST31: Wireless Charging System for Electric Vehicles (SRM)

Globally Auto manufacturers and tech firms are heavily investing in smart EV charging, striving to enhance its efficiency and affordability. Different EV models may require different charging connectors, and standardization has not been fully achieved. This lack of uniformity can lead to compatibility issues, making it challenging for users to find compatible charging stations for their specific vehicles. Wireless power transfer (WPT) for EVs has the prospective technology to overwhelm the problems of wired (plugged-in) chargers and eliminate certain hurdles to EV electrification for sustainable mobility. We developed the market-ready product of a 3.3 kW Wireless charger module with a modular design, enabling its seamless integration into various EVs. The proposed product has simple switching circuits that are capable of achieving (SAE) J1772 standards constant voltage (VC) and constant current (CC) charging with zero cross-coupling. The drive intelligent power novel power electronics resonant converter modules (IPMs) are planned using next-generation SiC IGBTs to deal with the thermal system performance and power density energy efficiency, system ruggedness, and reliability. This project employs EUC PCB with CAN and automotive communication protocols. Outer case and home allocation for the Rx charging pad with "Compliance Assurance": Ensuring the charging system adheres to both ICNIRP 2020 and SAE J2954 standards, IP 65 and IP 67. (ARAI/IEC- Certification). This developed Wireless Chargers has the following advantages over other chargers:
• Advanced Parking System - Convenient and effortless charging experience.
• The invented design is modular in nature; hence it can be designed in any EV with a High degree of freedom
• Reduced wear and tear on connectors with enhanced safety measures.
• Improvements in charging efficiency.
