“…As a result, coil dimensions related to transmission frequency and air gap determine transmission efficiency primarily. Nevertheless, this efficiency is also affected by adding other parts, such as ferrites or shielding [10]. Therefore, parameters such as transmission frequency, air gap, and coil dimensions need to be specified while designing the magnetic couplers of WPT EVs.…”

In challenging operational environments such as underground buildings beneath roadways, reliability and performance of wireless power transfer (WPT) systems for electric vehicles (EVs) heavily hinge on the operating temperature of the magnetic couplers. Addressing this, this study introduces a novel approach employing heat sink and thermoelectric cooler technologies to mitigate temperature rise in magnetic couplers, which is particularly crucial for high-power applications. Utilizing ANSYS simulation, the study evaluates a WPT high-power application coil model with a total output power of 2 KW and an 18 cm air gap, with a 3.5 cm adjacent alignment to enhance thermal performance on both transmitter and receiver sides. Results demonstrate significant thermal enhancement, reducing the temperature of coils from 63 • C to 54 • C solely with the heat sink and further down to 48 • C with the combined implementation of both heat sink and thermoelectric cooler. These measures effectively dissipate heat from the coils into the surrounding air, ensuring system efficiency and stability while facilitating functionality of system components.

“…Thus, the transmission efficiency depends mainly on coil dimensions related to the air gap and transmission frequency. However, the use of additional components such as ferrites or shielding also influences the transmission efficiency [4]. This must be taken into account in the optimization process.…”

“…The dependencies between transmission efficiency, litz wire dimensioning [6][7][8] and coil geometry [9][10][11] are extensively studied. The influence of ferrites [4,9,12,13] and shielding [14,15] is also well known in literature. The tradeoff between efficiency and compactness of magnetic circuit and power electronics is also extensively researched using pareto front of coil efficiency [16][17][18].…”

This paper presents a thermal investigation of lightweight on-board receiver modules of wireless power transfer systems for electric vehicles. The studied modules are capable of receiving up to 11 kW at a resonance frequency of 85 kHz over a distance of 110–160 mm. The receiver modules were built as sandwich and space–frame concept to design stiff and lightweight structures. The high transmission power of automotive wireless power transfer systems combined with the multi-part assembly of receiver modules led to challenges in heat management. To address this, the physical behaviour of the proposed lightweight concepts were studied on component and system level using a hardware-in-the-loop testing facility for wireless power transfer systems. Special emphasis was laid on the validation of a thermal simulation model, which uses analytical calculated power losses taking into account their temperature dependency. The proposed simulation model is consistent with the experimental validation of the critical active components. The performed systematic studies build the basis for a more sophisticated thermal dimensioning of various constructions for wireless power transfer modules.
