Abstract:

The paper proposes a bipolar coil arrangement method (BCAM) to identify a new anti‐misalignment positioning of overlapping (OV) coils in a bipolar pad (BP) for achieving high‐power transmission in a wireless electric vehicle (EV) charging system. Six different magnetic couplers with identical geometric dimensions, such as circular pad (CP), rectangular pad (RP), double‐D pad (DDP), DD quadrature pad (DDQP), BP, and four‐coil pad, are compared to identify a better performance charging pad. The performance evaluation for all charging pads is done by considering a vertical airgap (ΔZ) of 60–100 m

Abstract:

ABSTRACTDynamic response, lack of efficient power transfer, and high response time resulting in increased losses and reduced minimal efficiency are the major issues of the existing controls in the wireless power transfer (WPT) for EV charging applications. Model predictive (MP) control can handle several constraints and disturbances by predicting the future behavior of the system and generating control signals accordingly, making the system stable, and operating at high efficiency. This work proposes transmitter‐side model predictive (MP) control for the three‐level T‐type inverter–based wirel

Abstract:

This paper presents the experimental validation, using the opposition method, of a high-power three-phase Wireless-Power-Transfer (WPT) system for automotive applications. The system under test consists of three coils with circular sector shape overlapped to minimize the mutual cross-coupling, a three-phase inverter at primary side and a three-phase rectifier at receiver side. In fact thanks to the delta configuration used to connect the coils of the electromagnetic structure, a three-phase Silicon Carbide (SiC) inverter is driving the transmitter side. The resonance tank capacitors are placed

Abstract:

AbstractThe development of a battery management algorithm is highly dependent on high-quality battery operation data, especially the data in extreme conditions such as low temperatures. The data in faults are also essential for failure and safety management research. This study developed a battery big data platform to realize vehicle operation, energy interaction and data management. First, we developed an electric vehicle with vehicle navigation and position detection and designed an environmental cabin that allows the vehicle to operate autonomously. Second, charging and heating systems base
