System for monitoring and manipulation of electrically series connected cells of an electrochemical battery or a capacitor bank

Wherein each circuit comprises monitoring system for electric cells connected in series (1) of a battery, with one circuit (2) is provided for each cell, a data acquisition electronics for the detection of cellular parameters and a Balancierungselektronik for influencing the charge state of the cell and the circuits are connected in parallel to the respective cells, the circuits via control and data lines (8) are connected to form a circuit series and the first and / or last circuit of the circuit set at the same time control and data interface (12) to a higher level system (9). The task is to design a system with an as simple and unproblematic exchange of cells. The object is achieved in that all the circuits (2) are identical, each circuit respectively comprising a storage register, and all the memory registers of all circuits in the order of the cells are connected in series to each other to form a shift register as well as between each two adjacent circuits each level converter in the control and data lines are provided.
