NOVELTY - The system has a capacitor forming unit (4) at terminals of storage modules (1, 2, 3) constituting a battery. A resistor (5), a semi-conductor switch (6) and a voltage divider bridge are connected in series at the terminals, where the bridge has two resistors (7, 8). Semi-conductor switches (9, 10, 11) connect an RC circuit to the modules for determining an internal resistance and a state of each of the modules. A battery management system and a micro-controller system determine the state of the battery from the state of the modules.    USE - Used in a motor vehicle (claimed) for determining the health and load state of a battery e.g. hybrid battery and starter battery, during a passage in an after-sales network of a manufacturer and during a resale of the vehicle by resuming the network, where the starter battery ensures a stopping and a starting function of a heat engine of the vehicle.    ADVANTAGE - The system permits determining the total state of the battery and the modules of the battery and uses inexpensive components. The battery is constituted of modules and so it allows the system to perform a precise diagnosis of the battery and the modules to determine a diagnosis state of the battery and the modules at any time. The system evaluates the state of the battery during a passage in an after-sales network of a manufacturer and during a resale of the motor vehicle by a resumption in the network of the manufacturer, and allows the determination of regular statistics of the functioning of the batteries of a motor vehicle fleet for allowing the users to avail the statistics. The system permits to determine the internal resistance of the modules of the battery to stall the load state of the battery, to estimate the health state of the battery and to establish an ageing cartography for each module based on the sectioning of the battery. The system permits to determine the life expectancy of the battery at any time by considering its history.
