Abstract: This paper presents a direct experimental evaluation of differences between state-of-charge (SOC) and state-of-energy (SOE) metrics for lithium-ion storage batteries. The SOC-SOE metric differences are first investigated for single constant-current-constant-voltage (CCCV) cycles under room temperature (25°C) …
