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 system of electric batteries includes a plurality of batteries (HVB1, HVB2, HVB3) connected to each other by two polarities. Each battery has at least two relays (RN, RP, RA) for the connecting of poles of the battery to the two polarities. The system includes a secondary power supply to provide an activation energy to the relays. The system includes means of supervision to control the relays (RN, RP, RA) in a staggered manner so that each activation of a relay follows a previous activation by at least a predetermined time period (DT).

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: A method of controlling an internal combustion engine that includes an exhaust line fitted with a particulate filter, the method including: a) acquiring a charge parameter relating to a fill level of the particulate filter, b) comparing the charge parameter with at least one determined threshold, and c) bringing the internal combustion engine to a set operating point determined as a function of various criteria of differing levels of importance. Prior to c) and with one of the criteria being the mass flow rate of particles entering the particulate filter, a constraint level coefficient is determined as a function of the result of the comparing b) and applied to the particulate mass flow rate to weight importance of this criterion in determining the engine operating point.
