• Inductive Power Transfer (IPT) is emerging as one of the promising charging technologies for Electric Vehicles (EVs). With this technology, the power transfer takes place between two charging pads wirelessly, one on the ground and another attached to the vehicle's chassis. The type of charging pad used plays a significant role in determining the overall performance of IPT system and is, therefore, critical for the system. This paper presents a detailed comparison of the performance of various types of charging pads that are typically used in an IPT system, including rectangular, DD (two 'D' shaped pads), DDQ (two 'D' shaped pads along with a Quadrature 'Q' pad), and Bipolar. These pads are designed according to test-specifications in the Standard SAE J2954. The performance parameters presented here include the coupling-coefficient between the two charging pads and the power loss (in the ferrite, copper, shield, etc.) considering lateral misalignment in X and Y directions at different air-gaps. The paper also discusses which type of pad would be more suitable, considering these performance parameters. The analysis for the proposed work is performed through simulations in ANSYS Maxwell 3D. These findings are helpful in determining the suitable charging pads to meet the application requirements.
