Systems, methods, and devices for failure detection of one or more energy storage devices

Abstract

A battery management system (BMS) can manage an energy storage device. The BMS can include an ultrasound emitter, an ultrasound receiver, a data memory, and a data processor. The ultrasound emitter can direct ultrasound energy into the energy storage device, and the ultrasound receiver can detect ultrasound energy exiting from the energy storage device. The data memory can be configured to store (i) a capture data instance derived from the detected ultrasound energy exiting the energy storage device and (ii) baseline ultrasound data captured during a plurality of normal charging/discharging cycles of the energy storage device. The data processor can be configured to compare the capture data instance with the baseline ultrasound data, and determine an abnormal operating state of the capture data instance as compared with the baseline ultrasound data.
