As of my last update in September 2021, there were several advancements in power electronics for wireless charging of electric delivery vehicles and trucks. Please note that there might have been further developments beyond that date, so it's essential to consult more recent sources for the latest information. However, based on the information available up to September 2021, here are some notable advancements:
High-power wireless charging: Advancements have been made in increasing the power levels of wireless charging systems to accommodate the charging needs of electric delivery vehicles and trucks. Higher power levels reduce the charging time and allow for faster turnaround of vehicles, making them more practical for commercial use.
Dynamic Wireless Charging: Static wireless charging pads were initially popular for electric vehicles, but dynamic wireless charging systems have gained attention. Dynamic wireless charging allows for charging while vehicles are in motion, making it suitable for delivery trucks and other commercial fleet vehicles that need continuous operation without frequent stops for charging.
Efficiency improvements: Research and development efforts have been focused on improving the efficiency of wireless charging systems. Higher efficiency reduces energy losses during charging and ensures more effective use of electricity, which is crucial for large-scale applications like electric delivery fleets.
Resonant charging technology: Resonant wireless charging technology has been explored for its potential benefits in charging heavy-duty electric vehicles and trucks. It offers improved power transfer capabilities and can handle larger air gaps between the charging pad and the vehicle, which can be advantageous for commercial applications.
Grid integration and smart charging: Advancements have been made in integrating wireless charging systems with smart grids. This allows for optimized charging schedules based on electricity demand, renewable energy availability, and grid stability, ensuring that electric delivery vehicles are charged when it's most convenient and cost-effective.
Standardization efforts: Standardization plays a vital role in the widespread adoption of any technology. There have been ongoing efforts to establish common standards for wireless charging systems in the electric vehicle industry, including delivery vehicles and trucks. Standardization helps ensure interoperability, safety, and wider acceptance of wireless charging technology.
Scalability and cost reduction: As wireless charging technology becomes more prevalent, manufacturers have been working on improving scalability and reducing costs. This is crucial for making wireless charging solutions financially viable for fleet operators and commercial vehicle owners.
Keep in mind that the field of power electronics and electric vehicle charging is continually evolving, and there may have been significant developments beyond my last update. To get the most up-to-date information, I recommend checking recent research papers, industry reports, and news articles on advancements in wireless charging for electric delivery vehicles and trucks.
