High-power dynamic wireless power transfer (dWPT) technologies enable electric vehicles (EVs) to be charged as they are driven at highway speeds. These technologies hold significant potential to bolster consumer confidence and reduce onboard EV energy storage requirements as demonstrated in the High Power and Dynamic Wireless Charging project.
The Dynamic Wireless Power Transfer focus area will advance dWPT technology required to transition proof-of-concept technology to practical real-world applications and assess key performance metrics for ensuring safe, secure, and efficient power transfer.
This capability will especially benefit medium- and heavy-duty applications. However, lab-developed, high-power dWPT technologies have not yet been tested under real-world road conditions to understand the practical installation, operation, performance, and maintenance challenges to deployment. In practice, a lack of practical and verified methods of integrating dWPT hardware into different types of roadways without compromising performance and safety and comprehensive data on performance impacts under rigorous operating conditions will need to be addressed to better understand key system and component-level challenges.
