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 relates to a method and a system for managing the charging of a rechargeable battery by a voltage control or by a current control comprising a plurality (n) of branches connected in series, each branch comprising a plurality (p) of electrochemical elements connected in parallel. Each electrochemical element exhibits a charging profile (PC) comprising at least one plateau zone directly followed by a sloping zone in which the variation of the voltage as a function of the state of charge in the plateau zone is on average at least ten times less fast than the variation of the voltage in the sloping zone.

Abstract: The present invention is notably directed to methods for estimating a degradation of an electronically controlled electro-mechanical switch. The methods comprise determining a change of state of the contactor. They also comprise, computing, for each determined change of state, a wear increment WI of the contactor by: identifying a wear coefficient using a mapping between a last measured current through the contactor and a current range associated with a given wear coefficient; computing the actual wear WN of the contactor by adding the computed wear increment WI to a former known wear WI−1 of the contactor.

Abstract: A method and system are provided for estimating state of charge of a cell having a positive electrode, for example of a lithium phosphate type, the charge profile of which includes a range of state of charge between about 30 and about 90% in which variation of voltage is 10 times less rapid than for a state of charge higher than 90%. Determination of state of charge for a state of charge greater than 90% is based on either the use of a calibration relationship between cell voltage and state of charge when a current is passing through the cell that is less than a predetermined threshold value and its voltage has stabilized, or on the use of coulometry the result of which is corrected taking into account the accuracy of the current sensor.
