Current state-of-charge (SOC) and state-of-health (SOH) estimation techniques for commercial Li-ion batteries (LIB) rely almost exclusively on voltage measurements and current integration, which produce large errors. Recently, acoustic techniques, primarily ultrasonic time-of-flight (US-ToF) have be...
