Abstract: A method for estimating residual capacities of a plurality of batteries connected to an electrical power distribution network includes storing in the batteries energy coming from the network, releasing to return the energy to the network, gathering information relating to physical quantities to determine a state of ageing of each battery, during the storing, charging a selected battery until a predefined maximum charge level is reached, during the releasing, discharging the selected battery, if the selected battery has reached the maximum charge level during the storing, until a predefined minimum charge level is reached, or making the selected battery inactive if the selected battery has not yet reached the predefined maximum charge level, then measuring a level of energy yielded by the selected battery, and calculating a residual capacity of the selected battery based on the measurement of the level of energy yielded by the battery.

Abstract: The invention relates to a method and a system for allocating a power request PREQ to a plurality of batteries connected in parallel in an electrical energy storage system. According to the invention, the allocation system comprises a global control system that can determine a combination of batteries from said plurality of batteries, which is optimized to respond to the power request using the highest possible number of batteries, and allocate a power level to each of the batteries of said optimized combination.

Abstract: A method detects defects in an electrical power storage system including at least one battery. The method includes applying an instruction for charging or discharging the battery. The method also includes measuring the current passing through the battery during application of the instruction and calculating m×n mean errors (eTj(tij))1≦j≦m, 1≦i≦n between the measured current and the theoretical current of the instruction in m×n time intervals ([tij, tij+Tj])1≦j≦m, 1≦i≦n, respectively. The method also includes calculating, for each j between 1 and m, ej=max(eTj (tij)), where i=1, . . . , n. Lastly, the method includes incrementing a counter Cj if ej completely or partially exceeds a predetermined threshold. A defect is detected if Cj exceeds a predetermined threshold.
