SYSTEMS, METHODS, AND DEVICES FOR HEALTH MONITORING OF AN ENERGY STORAGE DEVICE

摘要

A health monitoring device includes an ultrasound source and an ultrasound sensor. The ultrasound source can be configured to generate and direct ultrasound at an energy storage device. The ultrasound sensor can be configured to detect ultrasound reflected from or transmitted through the energy storage device and to generate a signal responsive to the detected ultrasound from the energy storage device. A control unit can be configured to determine a state of health of the energy storage device based on the signal from the ultrasound sensor.
