Abstract

Objectives: The major short comings of WPT are power loss, magnetic field interference and heat emission. The proposed methodology addresses the issues encountered in the traditional wireless power transmission systems. Methods/Statistical Analysis: An Automated Battery Backup Approach (ABBA) is proposed here to initiate and terminate wireless charging system in auto mode. In this automated power transfer technique the battery pack device is knowledgeable of its own to take its decision based on the battery status. Findings: The exploration of electronic devices that ranges from handheld mobiles to unmanned vehicles and moving industrial robots, demand for wireless charging system. These nodes require to be instantly charged with dynamic energy. WPT (Wireless Power Transfer) is an effective strategy of transferring the electrical power from the source to the destination load that needs to be connected without wires. Many recent works in this area have discussed methods for improving efficiency and to prevent loss of power. The resistive heat in WPT is more than that of in direct contact charging, as continuous charging of the device happen even the battery being fully charged. Sometimes it causes short circuit damages and the battery will get easily damaged. Due to these issues of WPT the battery lifetime is also reduced. Applications/Improvements: The proposed ABBA methodology ensures a complete, fast, and safe charging mechanism for the battery backup process. This significant strategy is very much suitable for industrial environment to automate the process of transferring electric energy to the industrial gadgets or devices like unmanned vehicles and robots, based on the consumption of power.
