The invention relates to a method and a system for allocating a power request Pto 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.

Method and system for allocating a power request to a plurality of batteries connected in parallel

A system of electric batteries includes a plurality of batteries (HVB, HVB, HVB) 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).

System of batteries and method of controlling this system

The invention relates to a method for operating a motor vehicle, provided with an electric power supply system and a supervisor for managing the power supply of the vehicle from the power supply system, which comprises an initialization step, carried out by the power supply system, said step triggering an update of a series of parameters of the supervisor, said assembly including at least one physical operating threshold of the power supply system.

A method for adapting an engine-braking simulation for a vehicle provided with a regenerative braking device includes generating an arbitrated braking signal based on a simulated engine-braking signal developed on the basis of signals output from an acceleration pedal, and based on at least one signal output from at least one active safety system. The method also includes generating a braking instruction intended for the regenerative braking device by time filtration of the arbitrated braking signal.

Adaptation of a simulated engine-braking instruction

A motor vehicle driving assistance method including at least one electric motor powered by a battery and capable of driving drive wheels of the vehicle, the method including calculating an optimized consumption for the vehicle from an actual power consumption of the vehicle and from values collected by sensors of the vehicle, over a same path that the vehicle is in a process of traveling, the optimized consumption corresponding to a reference driving style; and informing the driver of a distance that he/she could travel using the power supply available on-board the vehicle if he/she were to adopt the reference driving style, or else the driver is informed of energy savings per unit of distance traveled that he/she might obtain if the reference driving style were adopted.

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. Thus, the engine is controlled taking account of the fill level of the particulate filter, making it possible to optimize a compromise between constraint on the particulate flow rate through the exhaust line and other engine control constraints.
