Half bridge Converter for Battery Charging Application Integral part of modern day electric vehicle is power electronic circuits comprising of AC-DC converters and DC-DC converters. This project presents a charging circuit for batteries used in electric vehicle. The portion of DC-DC converters mainly handle the purpose of battery charging.
The proposed charging system detects the normal connection of the battery in real time, starts charging, gradually matches the output voltage of the LLC AHB converter with the battery voltage, and gradually increases the output current of the battery. It smoothly charges Li-ion batteries.
The proposed smart battery charging system is technically characterized; in other words, no initial overcurrent occurs during battery charging and the battery does not charge when it is discharged or mis-wired according to the detection of the battery voltage.
One of the main features of half bridge converter is, it reduces the OFF-stage voltage requirement of the primary side switches to Vi apart from maintaining the bi-directional flux swing in the core. Thus the voltage stress and cost of the power switches is significantly reduced as compared to the push-pull topology.
The portion of DC-DC converters mainly handle the purpose of battery charging. The DC-DC converters include both isolated and non isolated ones. This project proposes isolated DC-DC converter for battery charging application with the concept of constant current charging. Here the current control strategy is mainly used for regulated current supply.
Single stage half bridge converter is proposed for dc voltage regulation and power factor correction. The performance of the converter is depends upon inductor operation mode, that is it depends on whether the inductor is operating on discontinuous conduction mode or continuous conduction mode.

Are Qi Wireless Chargers Safe? Or Do They Damage Batteries & Devices?
Battery charge cycles refer to the number of times a rechargeable battery can undergo complete charging before losing their ability to hold a charge. One charging cycle is completed when a battery goes from being completely charged to completely discharged. Charging a battery from 50% to 100% will therefore only use up half of a battery cycle.
