Abstract

This study presents the modeling of a used hybrid electric vehicle battery (also called second life battery), and its design and simulation for a standalone residential photovoltaic system. For this purpose, the battery was tested through capacity and electrochemical impedance spectroscopy tests (EIS). These tests were done with variable temperatures (0ºC, 15ºC and 30ºC), and results were used to fit an equivalent impedance circuit. This model was used to incorporate a second life battery to a PV system, which was simulated by using daily irradiance and load data for Tucson (AZ) under most various month (May).
