Abstract: A method of regulating temperature of an accumulator battery in a course of charging or discharging. The method includes: a) acquiring a state of charge relating to a level of charge of the accumulator battery, b) measuring values of the temperature of the accumulator battery at a first state of charge and at a second state of charge which is different, c) estimating, as a function of the values of the temperature measured in b), the value of the temperature of the accumulator battery at a future third state of charge, and d) controlling the temperature of the accumulator battery as a function of the value of the temperature estimated in c).

Abstract: A method is for protecting an electrical architecture including a protective device provided with a protective fuse capable of melting in a deteriorated mode of operation during which a breaking current having an amperage greater than a threshold is flowing through the architecture. The method includes, in a nominal mode of operation, periodically estimating a temperature of the fuse and controlling an amperage of a useful current flowing through the fuse such that the estimated temperature remains below a melting temperature of the fuse.

Abstract: A module of elementary electrical energy storage cells includes a first set of elementary cells that are interconnected so as to supply a first voltage in a first voltage range and a second set of elementary cells that are interconnected so as to supply a second voltage in a second voltage range. At least one elementary cell from the second set is arranged between two elementary cells from the first set.

Abstract: A method for managing a battery located in a motor vehicle includes cooling the battery when a data item indicative of the temperature of the battery exceeds a first threshold, stopping the cooling of the battery when the data item indicative of the temperature of the battery drops below a second threshold, notably lower than the first threshold, and adjusting at least one of the first and second thresholds.

Abstract: A method for managing the temperature of a battery of an electric or hybrid vehicle includes recording a temperature value at which the cooling or heating of the battery is triggered. The method further includes, for two consecutive values in a predefined sequence of states of charge: a step of comparing a real gradient to a reference gradient of the battery temperature; and a step of modifying, depending on the comparison, the value of the trigger temperature, or the value of the power output by cooling or heating the battery; and also includes applying the modified trigger temperature or output power for the following two consecutive values of the state of charge of the battery in the predefined sequence.
