Abstract: The quality of a particular physical or chemical parameter which exists at the cells of a multicell battery, such as for example, the voltage, current or temperature parameter at each cell, is continually monitored by a circuit arrangement which includes a separate measuring circuit for each cell. Each measuring circuit receives at its input, a signal representative of the value of the quality of a particular parameter, and produces at its output an electrical signal the length of which is proportional to the value of the signal at its input. The outputs of the measuring circuits are connected to a measuring analyzer circuit containing a controller which generates a starting signal that is applied to the measuring circuits to enable or actuate them one after the other, so that the outputs of the measuring circuits are in turn successively applied to the input of the analyzer circuit, which includes a display that provides an indication of the quality of the parameters which are being monitored.
