Optimizing WPT Receivers for Enhanced Performance and Cost Efficiency in Electric Vehicles

Wireless power transfer is one of the most interesting technologies in transportation. Resonant inductive power transfer would allow electric vehicles to be recharged wirelessly and dynamically. As new vehicle models come onto the market, it will be important to ensure that vehicles are equipped with optimised receivers that get catch the desired power and minimise the use of materials. The distance between the transmitter and receiver has a major impact on the amount of power that can be transmitted. To address that, this paper proposes a model to study the optimisation of receivers mounted on electric vehicles, allowing optimised power reception for taller vehicles such as SUVs and saving up to 4% and 3% of receiver costs for sports cars and utility vehicles respectively. The implemented model will also be replicable and scalable in other contexts to certify the optimal sizing of vehicle mounted receivers.
