Battery Hardware Simulator, Kian N. Orang, Marcelo Garcia

Electrical Engineering

This project aims to develop a battery hardware simulator, which will serve as a tool for studying microgrids. The primary objective is to create a simulation system that can emulate various battery technologies that are used in microgrids, including lithium-ion and lead acid. By utilizing this battery simulator, Cal Poly students can safely test battery management systems and battery-sensitive electronics without the inherent risks associated with real batteries. Our project implemented this design with a 4-quadrant programmable power supply (ITECH) connected to an AP Systems grid tied inverter. The power supply acts as the battery which can receive or supply …

Optimizing Battery Performance: Investigating The Long-Term Impacts Of Bidirectional Battery Management Systems On Battery Cells, Drue Nathaniel Haskins

Graduate Research Theses & Dissertations

With the increased use of batteries in everyday life, it is crucial to have a robust and reliable battery system that can continue to power our devices. This paper will investigate the reliability, impact on the batteries, and functionality of the bidirectional battery management system (BMS). The design uses two bidirectional switches for each cell, one in series with the cell and one in parallel with the other bidirectional switch and cell. This will allow the cell to be taken in and out of the circuit for any reason determined by the BMS. Taking the battery in and out of …

Technical And Economic Feasibility Of A Microgrid For A Fire Station In Humboldt County, California., Nishaant Kumar Sinha

Cal Poly Humboldt theses and projects

Microgrids are emerging as a promising solution to unreliable grid energy. Today, California is not only witnessing grid resiliency challenges from natural disasters such as wildfires, earthquakes, floods and heatwaves, but it is also seeking to green the grid and bring more renewables online. For example, Humboldt County, where this project is focused, has recently experienced an earthquake of 6.4M (on December 22nd, 2022), which shut down the regional grid for ~20 hours.

Microgrid adoption enables critical facilities to operate seamlessly. The Humboldt Bay Fire Station (HBFS) No.1 is one such example, where first responders work to protect citizens against …
