An improved system for estimating the SoC of a battery is provided. In one embodiment, an ultrasonic pulser transmits a multiple-cycle sine wave at an excitation frequency through the thickness of a lithium-ion battery. Due to the inherent acoustic nonlinearity of composite materials within the lithium-ion battery (electrodes and electrolytes), part of the ultrasonic energy is converted into a second harmonic wave. An ultrasonic receiver detects this wave on the opposite side of the battery. The strength of the second harmonic is quantified by a nonlinear parameter β′, which correlates linearly with the battery's SoC, increasing with charging and decreasing with discharging. By establishing a linear relationship between β′ and SoC through non-destructive calibration, the system can then estimate the SoC of any battery by measuring the nonlinear parameter β′. This technique enables real-time, accurate, online and offline SoC estimation, making it highly suitable for vehicular applications and non-vehicular applications alike.
