Abstract
A measurement circuit for a modular system of cells electrically connected in series, in particular for electrical accumulator batteries, includes individual interfaces respectively connected to each power terminal of a different cell and each including a single-wire measurement output for a current measurement signal to be transmitted to a common transducer via a common single-wire connection. The interfaces each incorporate a switchable measurement current generator. They are connected in series by successive elements of a single-wire connection enabling serial transmission of individual switching control pulses grouped into streams for the current generators.
