    Abstract: The present invention is notably directed to methods and systems for protecting a pre-charge circuit. The present invention is further directed to related computer-implemented program product. The method comprises monitoring the current flowing through the current limiting device, calculating the energy loading of the current limiting device over time, and managing the system state to prevent damaging operation of the pre-charge circuit.

    Abstract: The invention concerns a multi-battery assembly, and a container comprising such an assembly, for use in particular in the field of high energy-density assemblies comprising a plurality of Ni—Cd, Ni-MH, lead-acid or Li-ion stationary batteries stored in a container or a library-like room. The multi-battery assembly comprises at least three rows (1 to 4) of batteries (12 to 23) connected in series and/or parallel, including two end rows (1, 4) and at least two intermediate rows (2, 3), each row being connected in series and/or parallel to at least one adjacent row, extending in a first direction (d1), and comprising at least one level (36 to 38) of a plurality of batteries connected in series and/or parallel, each of the levels extending in the first direction (d1). At least each intermediate row is a row that is movable relative to an adjacent row in a second direction (d2) substantially perpendicular to the first direction (d1), and is connected in series and/or parallel to said adjacent row by one of the batteries of one of the levels of same and by one of the batteries of one of the levels of said adjacent row by means of a connection element (60 to 63) that is configured to maintain the connection between the movable row and the adjacent row while allowing the movable row to move relative to the adjacent row in the second direction (d2), so as to allow at least one temporary corridor (50) to be created between the movable row and the adjacent row without disconnection.

    Abstract: A safety device (19) for a battery (12) being designed so that an electrical connector (18) can be connected to the positive (14) and negative (16) electrical terminals of the battery (12) in a first (A+, A−) or a second (B+, B−) connection position, the safety device (19) being adapted to be selectively positioned in a first or a second safety position so that only the desired connection positions are accessible to an electrical connector (18). A battery including the safety device or a set of such batteries and a method for making such a set of batteries safe.

    IPC: G01R31/36

    Abstract: The invention relates to a method for determining the value of one or more parameters relating to the state of health of at least one accumulator of a battery that is intended to provide electrical energy to an external application, an electronic battery management system implementing this method, and a battery provided with this system. The method comprises the steps consisting in particular in: making a series of measurements of N samples, where N≥3, of at least the voltage, the current and the cumulative capacitance, at the terminals of said accumulator, when charging or discharging said accumulator; —creating a minimization loop by varying a current value of the first parameter of the accumulator from a determined initial value, comprising the following steps: (i) calculating N estimated values of a second parameter linked to the state of charge of the accumulator from the current value of the first parameter and said N samples, respectively (ii) calculating N theoretical values of the second parameter (iii) varying the current value of the first parameter, repeating the preceding calculation steps for each variation of said current value of the first parameter, and determining the value of the first parameter as being the current value of the first parameter that minimizes the difference between the estimated values and the theoretical values of the second parameter.
