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.

Module of primary cells and device for storing electrical energy

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.

Method and device for protecting an electrical architecture

A method manages a power train of a motor vehicle including a heat engine and an electric motor electrically linked to a power battery. The method includes controlling a heating system for heating the power battery according to at least one measurement of a temperature representative of an operation of the heat engine.

Method for managing a hybrid power train of a motor vehicle

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).

Method of regulating the temperature of an accumulator battery

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.

Method for managing the cooling of a battery with adjustable cooling thresholds

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.

Method for managing the temperature of a battery of an electric or hybrid vehicle

A method for charging a battery, including: determining a final state of charge and a final temperature of the battery; and calculating charging power and/or cooling power required to reach the two final values within a minimum amount of time.

Method for charging a battery for supplying power to a drive motor of a motor vehicle

A battery pack includes at least a first stack of battery modules, and a second stack of battery modules, each stack including a plurality of battery modules arranged in parallel in side by side relationship extending in a longitudinal direction, the battery pack further including at least one heat exchanger interposed between the first and second stacks, the heat exchanger being in thermal contact with interstack coupling surfaces extending in a longitudinal and transversal plan [L-T] of the battery modules. The invention also relates to a corresponding heat exchanger.
