Performance of Charging Batteries by Using Compound Wireless Power Transfer System

Abstract

The charging power is being augmented to enhance the ease of electric automobiles. Nonetheless, high-power charging may lead to significant and apparent issues with battery heat production. Consequently, a prominent research concern is achieving an optimal equilibrium between rapid charging and preserving battery performance. An LCLC-compensated combination inductive and capacitive wireless power transfer (COMPT) system for battery charging is a novel system in this work. Inductive and capacitive power transfer (IPT and CPT) systems are combined in the circuit design. A detailed analysis of the combined circuit architecture’s working principle clarifies the link between circuit parameters and system power. For inductive and capacitive coupling design, finite-element analysis is used. The connector plate equivalent circuit model will be created for 100 kW. Design and implementation of the COMPPT system will demonstrate combined inductive and capacitive coupling. Both the inductive and capacitive couplers are 500 mm × 500 mm. Many air gaps are investigated for each coupler, ranging from 150 to 750 mm. Combining IPT and CPT systems yields COMPT’s output power. The prototype will generate 95.46 kW of power with 95.7% efficiency at a 1-MHz switching frequency and operate better under misalignment than the IPT System. The inductive-capacitive combination COMPT technology may be suitable for electric battery charging. The special environmental conditions that affect energy transfer, such as heat, rain, snow, and other important major environmental factors that affect energy transfer this research examines several lithium-ion, lead-acid, and nickel-metal hydride batteries, using experiments to analyze the impact of pulse charging and constant current charging on battery performance. A suggested assessment methodology assesses the viability of various charging techniques, including rapid charging for power batteries, based on charging duration, rechargeable capacity, temperature variations while charging, and battery life degradation during cyclic charging.
