Stationary BESS Peukert Capacity Derating, C-Rate Kinetics, and Inverter Tare Loss Benchmark Matrix
Electrochemical capacity retention curves across 0.05C to 2.0C discharge rates and continuous 15W–65W inverter quiescent tare dissipation under IEEE 485.
1. Abstract & Dataset Scope
Provides empirical and mathematical benchmark matrices evaluating battery usable capacity (Ah and kWh) as a function of continuous discharge rate, depth of discharge operational limits (50% vs 80% vs 95%), and inverter standby tare power dissipation (Ptare = 15W–65W) in residential stationary storage systems under IEEE Std 485 and UL 1973.
2. Experimental & Simulation Methodology
Simulated and experimentally validated using multi-cell LiFePO4 and flooded/AGM lead-acid discharge test beds under controlled 25°C ambient conditions across normalized discharge rates from C/20 to 2C.
