Developing Energy Harvesting Tiles from Footsteps with Battery Management System and Monitoring Application
2025
Overview
Renewable energy is energy that will not run out along with its use and the energy can be directly used or stored in an energy storage system. If the pressure from footsteps can be converted into electrical energy, this energy can be obtained every day. To ensure safe and monitored energy harvesting from piezoelectric tiles, a Battery Management System (BMS) and monitoring application have been developed. The use of piezoelectric sensors will convert any form of pressure or vibration into electricity. The Battery Management System (BMS) will collect data on the voltage of each battery cell, the current flowing in and out, and the battery temperature. Based on sensor data, the BMS will implement the following safety measures and functions, i.e. Over Voltage Input Safety (OVIS), Over Current Input Safety (OCIS), Over Current Output Safety (OCOS), Battery Under Voltage Protection (BUVP), Battery Over Voltage Protection (BOVP), and Cell Balancing (CB). The BMS is also designed to control the limit of each cell′s voltage and current. A monitoring system was developed to make sure they are working properly. The system developed was in the shape of web and mobile applications which show and update data of the BMS in real-time. From these applications users can control the usage of the battery as a power source by turning the switch on the applications on and off. Switch on each application will update based on the latest data. Based on the research in this manuscript, 1 tile with 64 piezoelectric sensors can generate a voltage of 18.75 V from 189 footsteps. The BMS system function test, and data control test were successfully executed. Based on the conducted experiments, the maximum deviation in voltage readings was 0.046 volts, while the deviation in temperature readings was ±1 degree Celsius. However, current readings remain inaccurate.
