The present invention relates to an electrochemical energy storage device and a method for controlling a cell module (1) in an electrochemical energy storage device. According to the present invention, the clamping voltage (UHV+, UHV-) of the electrochemical energy storage device (3) are detected. The clamping voltage (UHV+, UHV-) is compared with a setting value (Usoll). To determine probability of a specific switching state to achieve the setting value (Usoll), a first signal (S1) is transmitted to the cell module (1). A second signal (S2) which indicates the specific switching state of the cell module (1) related to polarity for the electrochemical energy storage device (3), is transmitted to the cell module (1). |
