Intelligent phase change heating module system

Abstract

A smart phase change material (PCM) heating module system for electric kettles and similar household heating containers is disclosed. The system includes a modular, thermally rechargeable PCM heating unit, which integrates a thermoelectric generator and a control module. During kettle heating, the PCM heating unit stores latent heat using a PCM material with a melting point of approximately room temperature to 100°C. This heat is released after the heating cycle, efficiently maintaining water temperature without requiring continuous power. The thermoelectric generator uses thermal gradients to generate electricity, supplying sensors or electronic devices. The system may optionally include a data logging module for tracking energy use and carbon reduction (and can be integrated with carbon credit or NFT platforms), and may also be equipped with a solar preheating interface and various user interfaces.
