Abstract
A vehicle can comprise a battery cell, a monitoring device, and a controller. The monitoring device can comprise an ultrasound source and an ultrasound sensor. The ultrasound source can direct ultrasound at the battery cell, and the ultrasound sensor can detect ultrasound transmitted through or reflected from at least a portion of an interior of the battery cell. The ultrasound sensor can generate one or more signals responsive to the detected ultrasound. The controller can process the one or more signals from the ultrasound sensor and can output an indication of an internal state of the first battery cell.
