Abstract

Electrical energy is a basic need for society and is a fairly economical resource that can be used for various activities. Human activities are supported by electrical energy. Electrical energy has important role in supporting all activities such as the industrial, commercial building, transportation and housing sectors. Water pump Shimizu PS-135 E is a type of water pump that is widely used in family activities, its function is to supply water from water sources (reservoirs, wells) for family needs such as bathing and washing. The pump relies continuously use of electrical energy, it means that, if this energy source runs out, the pump will not be able to operate automatically and ultimately. For this reason, in this research, the LiFePO4 type battery is used as an alternative energy source to overcome the above problems. The results of the analysis in this research show that to run the water pump for 1.5 hours a 42,000 mAh 12 Volt LiFePO4 battery is required which is arranged in a 4S - 7P manner and as a battery protector a 60 A Daly type BMS is used. Testing the load on the water pump until the battery cut time showed that the battery drain time was 1.3 hours, the battery condition was 20% with a voltage of 12.89 Volts. AC output voltage 230.4 Volts, current 1.145 A, power (P) = 195 Watts, Power Factor 0.72. The volume of water produced in 1.3 hours (78 minutes) is 2,182 liters.

Abstract

Phase-to-ground leakage in low-voltage network systems can cause transformer damage due to overload. Overloading on transformers is not caused by customer usage but rather by wasted electrical energy to the ground which causes losses. If there is a current leakage, the potential difference between neutral and ground is measured to produce a voltage value. Considering that there is little written about transformer damage caused by current leakage to ground in low voltage network systems, in this research a tool is made that can detect current leakage to ground in low voltage network systems using the ZMPT101B voltage sensor based on IoT. This research is in the form of design and manufacture of a leakage current detector to ground. The method used is the Research and Development method (research and development), namely in the form of observation, literature study. The research stage starts from a literature study in the form of finding references related to research, designing tools, making tools and programs, and testing the tools that are made. Based on the results of Based on the results of the research, this tool can detect leakage current to the ground from the lowest voltage of 24.3 Volts to the highest voltage of 184 Volts so that it can be displayed on the LCD and the blynk application and the system automatically sounds a buzzer as a warning of current leakage to ground. .

Abstract

This study aims to enhance estimation accuracy and energy management by incorporating thermal aspects into Battery Management Systems (BMS). Through experimental evaluation and mathematical modeling, key parameters such as charging time, internal resistance, State of Charge (SOC), Depth of Discharge (DOD), and effective capacity are analyzed. The SOC profile follows a logistic curve, with system energy efficiency ranging from 93% to 97%, depending on internal resistance variations. An Adaptive Kalman Filter (AKF) is applied for real-time SOC estimation, achieving an accuracy of ±1.5%, while a Long Short-Term Memory (LSTM) neural network performs time-series SOC prediction with an RMSE of 0.95%. Furthermore, three-dimensional thermal modeling reveals a significant increase in resistance beyond 45 °C, emphasizing the effect of temperature on battery dynamics. These findings highlight the importance of integrating real-time estimation and AI-based prediction algorithms into adaptive BMS architectures, contributing to advancements in intelligent energy management for electric mobility and stationary storage systems. However, this study was conducted under controlled temperature and fixed charging conditions, which may limit generalization to dynamic real-world operations; future work will address these factors.
