Benchmark Matrix: Residential BESS Cycle-Life Degradation, Calendar Aging, and Ambient Temperature Derating Miad Saadidi (24671005) Electrical engineering not elsewhere classified Energy storage -- Ontario battery storage prior <p dir="ltr">### 1. Physical Motivation & Scope</p><p dir="ltr">This benchmark dataset provides empirical and deterministic degradation matrices for stationary residential Battery Energy Storage Systems (BESS), evaluating electrochemical capacity retention (%), internal resistance growth ratio (R_growth), and calendar fade across lithium iron phosphate (LiFePO4) and nickel manganese cobalt (NMC) chemistries. </p><p><br></p><p dir="ltr">It tabulates performance across equivalent full cycles (500 to 6,000 EFC), depth-of-discharge boundaries (50%, 80%, 100% DoD), and extreme ambient thermal ranges (-10°C to +45°C / 14°F to 113°F).</p><p><br></p><p dir="ltr">### 2.
