Abstract:
A measurement circuit for a modular system of modules electrically connected in series, each consisting of one or more elements for producing, storing or converting electrical energy, and with which are associated individual measurement interfaces for each module and a measurement signal transducer to which the interfaces successively supply their measurement signals via a first serial link in response to individual interface selection pulses transmitted from a common logic unit via a second serial link, wherein said successive interfaces are interconnected by elements of said first and second links, at least two interfaces corresponding to two successive modules being connected by two link elements, one of which is a first link element and the other of which is a second link element, each incorporating a protective diode connected in series to protect against a reverse voltage, in particular in the event of a break in the electrical continuity between the modules to which the interfaces between which said diodes are connected correspond.
