15. A vehicle comprising:
a first battery cell;
a monitoring device comprising at least one ultrasound source and at least one ultrasound sensor, the at least one ultrasound source being configured to direct ultrasound at the first battery cell, the at least one ultrasound sensor being configured to detect ultrasound transmitted through or reflected from at least a portion of an interior of the first battery cell and to generate one or more signals responsive to the detected ultrasound;
a controller comprising one or more processors and one or more non-transitory computer readable storage media storing instructions that, when executed by the one or more processors, cause the controller to process the one or more signals from the at least one ultrasound sensor and to output an indication of an internal state of the first battery cell; and
a performance sensor configured to detect a performance characteristic of the first battery cell and to generate a one or more performance signals responsively thereto,
wherein the one or more non-transitory computer readable storage media store instructions that, when executed by the one or more processors, cause the controller to output the indication of the internal state of the first battery cell based on the one or more signals from the at least one ultrasound sensor and the one or more performance signals.
