Abstract

The Government through the Ministry of Energy and Mineral Resources and PT Perusahaan Listrik Negara (PLN Persero) have decided to increase the basic electricity tariff as of July 1, 2022. This certainly impacts the operational costs in the provision of education at Faletehan University. With this increase in operational costs, efforts to improve the efficiency of electricity usage are needed, one of which is through the implementation of energy management in managing electricity usage at Faletehan University. Energy management itself is an integrated activity carried out by an institution to control energy consumption in order to achieve effective and efficient energy utilization to produce maximum output through structured and economical technical measures to minimize energy consumption, as stipulated in Regulation of the Minister of Energy and Mineral Resources of the Republic of Indonesia No. 14 of 2012. Based on this, research related to the implementation of energy management as an effort to improve the efficiency of electricity usage is needed, with the research location at Faletehan University. This research aims to identify where and how much energy is used by Faletehan University and what steps can be taken to conserve energy as an effort to improve the efficiency of electricity usage at Faletehan University

Abstract

This paper presents an analysis of the design and implementation of a state of charge (SOC) monitoring system for solar-wind hybrid systems using the Coulomb Count method. The purpose is to obtain real time measurements of voltage, current, temperature and SOC according to the battery management system. It is observed that when the 4.2 Ah battery is discharged, there is a significant drop in voltage and SOC, which is at a value of 45% to 40%, so that the cut-off voltage, namely the voltage required to avoid overcharging, is chosen at to avoid overcharging. It is chosen at 50% SOC and the voltage of 12 volts. When charging the 4.2 Ah battery, the voltage reached 16 volts at 75% SOC, with the battery temperature rising above 40°C, this value shows the importance of the cut-off voltage limit to avoid overcharging. Charging a 110 Ah battery with a solar/wind hybrid system using a PWM charger controller through the bulk, absorption and float phases shows that the bulk phase lasts about 18 minutes with an initial SOC of 47% and the absorption phase lasts 21 minutes and the last is the float phase where constant voltage and current occur for only 5 minutes. It is also found that the system can effectively follow the battery charge curve, preventing damage and ensuring the optimal condition of the charge controller.
