Abstract
An electrochemical storage device including a state detector, has an electrochemical storage device, which has a wall that surrounds an electrochemical storage material. The state detector has at least one ultrasonic transmitter and at least one ultrasonic receiver, which are attached to the side of the wall facing away from the electrochemical storage material. The electrochemical storage material is subject to a volume change during operation of the storage device, and the electrochemical storage material is liquid during operation of the storage device and is in direct contact with the wall and the ultrasonic transmitter and the ultrasonic receiver are attached to the wall in such a way that the ultrasonic transmitter and the ultrasonic receiver are acoustically coupled to the wall.
