- the data used for example the energy status value and / or the power value
- the data used from one of the intermediate operating points to determine a corresponding characteristic operating point are adapted according to the structure of the the battery, in particular in the manner in which the unit cells of the battery are electrically connected to each other.
- each implementation of a test consists in carrying out a step of discharging the standard battery from a known energy state and a known discharge power determined from one of the points of the test. set of intermediate operating points determined to obtain a corresponding remaining energy by measurement. Therefore, the characteristic operating point is formed by the combination of the known energy state, the known discharge power and the measured remaining energy. More particularly, a test can resume the steps of the characterization procedure of the standard unit cell but this time applied to the battery.

- the system is an electric car and the monitoring of the energy state will optimize the autonomy of the electric car depending on the remaining energy actually available in the battery.
- the determination step E2 of the set of intermediate operating points comprises at least one cycle of steps.
- This cycle of steps includes a step E2-1 of choosing at least one set of potential intermediate operating points from the initial operating point set. These intermediate operating points chosen are called “potential" because we will seek to determine if they can agree, that is to say if they are sufficiently representative of all the initial operating points.

It is then understood that for each set of potential intermediate operating points chosen, the associated established surface comprises the points of said set of potential intermediate operating points and other computed or calculable points which it is easy to find when the established surface is known.
- an equation of said established surface could be determined by interpolation of points, for example using the Delaunay triangulation.
- the established area is such that all points on this surface whose coordinates in terms of energy state and power are identical to those of the initial operating points are found (i.e. remaining energy is determined for example by interpolation).

- the cycle of steps also comprises a comparison step E2-3 between each established surface and all or part of the initial operating points.
- the initial operating points used to establish said surface will not be compared with the latter because identical, this in particular to accelerate the processing of the cycle of steps.
- the cycle of steps may comprise a validation step E2-4 of the choice of said at least one set of potential intermediate operating points as a function of the result of said comparison. For example, this validation may be recorded if all the initial operating points are close enough to the corresponding operating points of the associated established surface.
- a set of potential intermediate operating points When a set of potential intermediate operating points is validated, it means that it can be used as part of the determination step E3 of the set of characteristic operating points. In other words, a set of valid potential intermediate operating points can form / constitute the determined set of intermediate operating points.

- the validation step E2-4 comprises enabling said at least one set of potential intermediate operating points chosen if, for each pair of points, said difference, or a value representative of the difference, is less than a threshold (this threshold corresponding to S in the example above) then forming a first optimization condition.
- the value representative of the difference may, for example, be a percentage, typically the threshold is then less than 3% so that the value of the remaining energy of said point of said established surface is between -3% and + 3% compared to the value of the corresponding initial operating point.
- the method may comprise a selection step E2-5 of a single set of intermediate operating points among said several sets of validated intermediate operating points. From then on, this selected set will form the set of determined intermediate operating points.
- the selection step E2-5 comprises establishing, for each of the established areas associated with the sets of validated potential intermediate operating points, an average value of the determined difference between the the remaining energy values of the points of each pair associated with said established area, the set of selected intermediate operating points corresponding to that associated with the established area having the lowest average value.
- this new condition makes it possible to choose an optimal solution among the set of valid solutions (surfaces), that is to say that mathematically for any operating point P, - (XSOE /, ypd *, z E rw ) belonging to the set of initial points, and for any operating point of the established surface of coordinates S '(XSOEÎ, ypd /, z En -) associated with a set of intermediate operating points
- the validation step E2-4 can comprise a first phase in which it is checked whether, for each pair of points, said difference, or a value representative of the difference, is lower than the associated threshold (in the example above) and a second phase in which it is confirmed the validation of said set of potential intermediate points that if the average value (or a value representative of this average value) of the determined difference between the remaining energy values of the points of each pair associated with said established surface is less than a corresponding threshold (it is possible to then have Moy (
- a is defined in order to keep a resemblance between the initial and final (optimal) surface. The right choice of to make the surface (optimal) flat and avoid, locally, the presence of small bumps.
- the latter comprises a first initialization step E4 in which four end operating points chosen from set of initial operating points, the remaining initial operating points forming a set of internal operating points.
- the end operating points are formed by mesh points that "enclose" the internal operating points.
- the four end points are advantageously constituted by the following points: (0, Pmin, 0), (0, Pmax, 0), (1, Pmin, z1) and (1, Pmax, z2) with z1 and z2. associated values of remaining energy having been determined in particular during the characterization of the standard unit cell.
- the latter comprises a second step E5 comprising a step of defining E5-1 of a variable Nb p0 int representative of a number of operating points of the set of points. internal operation to use.
- the second step includes a step E5-2 of setting implementing the cycle of steps described above (steps E2-1 to E2-4 or E2-5 of Figure 2).

- the selection step (E2-1) is such that each set of potential intermediate operating points selected comprises (preferably only) the four fixed end points and one of said possible combinations.
- Nbpoint is equal to 1 (in other words, the definition step E5-1 of Nb p0 int initializes Nbpoint to 1). If no set of potential intermediate points is validated during the implementation of the cycle of steps associated with the first iteration of the second step, the method then comprises a second iteration of the second step E5 for which Nb p0 int is 2 (at the output of step E5-2, we return to step E5-1 where the variable Nb p0 int is incremented - the increment being made from 1 to 1).
- a step (not shown) consecutive to step E5-2 can make it possible to check if no set has been validated and if so the process returns to step E5-1, especially as long as Nb p0 int is strictly less than 3, where Nbpoint is incremented.
- all the sets of potential intermediate points chosen here form a set of corresponding corresponding surfaces that must be validated or not.
- Nbpoint 1 or 2
- the number of sets of potential intermediate operating points is such that a "raw" attack by testing all associated established surfaces is achievable, with computing means available to the skilled person, within a reasonable time.
- the step of determining the set of intermediate operating points can be stopped and the set intermediate operating points determined is formed / constituted by the set of potential intermediate operating points valid.
- this second step E5 can be described as non-random oriented part.
- the method comprises a third step E6 comprising the following steps:
- Nb p0 int incrementing Nb p0 int (preferably after the first incrementation of this step E6, Nb p0 int is equal to 3) and randomly forming sets of Nb p0 int points (E6-1), preferably distinct, chosen from the points of set of internal operating points until the number of sets of Nb p0 int points equals a predetermined threshold less than the number of possible combinations of Nb p0 int points out of the total number of points in the set of internal operating points,
- each of the surfaces of the plurality of surfaces being defined from the four fixed endpoints and from one of the sets of Nb p0 int points randomly formed ( in other words, these points are part of said surface),
- step E6-2 of FIG. 5 The steps of determining the plurality of surfaces, comparing and defining the points of step E6 are represented in step E6-2 of FIG. 5.
- the predetermined threshold less than the number of possible combinations of Nbpoint points out of the total number of points of the set of internal operating points makes it possible to limit the number of surfaces. established.
- This threshold can be a function of the calculation power available, typically it can be less than 15000.
- the optimization condition of the step of defining the points of step E6 may be identical to the first optimization condition, moreover the second optimization condition may also apply. It is then understood that all that has been said above for the validation step E2-4 of the cycle of steps is advantageously applicable in the step of defining the points of the step E6 in order to validate or not the points used to define a surface of the plurality of surfaces as validated intermediate operating points.
- the second step E5, or the third step E6 it is possible for the second step E5, or the third step E6, to find several sets of validated intermediate operating points.
- the selection step E2-5 described above can also be applied as part of the second step E5 or the third step E6 in order to select only a single set of validated intermediate operating points. .
- Nb p0 int is equal to 6 or when Nb p0 int is equal to 6. This limit therefore makes it possible to stop the process and to report a problem to an operator if no solution is found at this time.
- step E6 Nb p0 int valid surfaces
- step E8 the most optimal at the end of the method among the Nb p0 int valid surfaces
- the cycle of steps is carried out so that after the establishment of a surface, the associated comparison step is set prior to the establishment of any other surface, in order to validate or not the potential intermediate operating points associated with said established surface.
- the step of determining the intermediate operating points is stopped and the set of potential intermediate operating points validated is used in the step of determining the set of characteristic operating points as a set of determined intermediate operating points.
- an iteration of said cycle of steps involves the choice of a single set of potential intermediate operating points.
- the choice is validated, the step of determining the intermediate operating points is completed, otherwise a new iteration of the cycle is performed with a new single set of potential intermediate operating points chosen.
- the purpose of the two preceding paragraphs is also valid in the context of the implementation of the second stage or the third stage, even if the corresponding predetermined threshold has not yet been reached.
- the present determination method has been used to characterize a battery of which a unit cell is usually characterized by 36 initial operating points at a given temperature (Fig. 2).
- the method has been able to put forward less than 8 operating points of the relevant initial set of points to determine the set of characteristic operating points.
- Tests were therefore conducted to characterize the type of battery with the 8 points put forward and with the initial 36 points in order to obtain two separate maps representative of the energy behavior on 8 points and on 36 points.
- the mappings obtained were used in the context of simulation respectively on a first battery and on a second battery according to the same algorithm for monitoring the state of energy for the same behavior in terms of power consumption and in conditions of identical temperatures.
- Figure 6 illustrates two curves representative of the use, the curve C1 corresponds to the follow-up using 36-point mapping and C2 curve is tracking using 8-point mapping. It can be seen that the final difference between the simulations is relatively small (less than 2.4%) and is largely acceptable in view of the time gained and the cost associated with the characterization of the battery.
- a device may comprise a calculator and means for implementing the method for determining the set of characteristic operating points and / or the means for implementing the method for characterizing a predetermined battery provided with a plurality of unit cells for a plurality of temperatures.
- the device may comprise as many elements as steps of the associated method, it is understood that each element is configured to allow the implementation of a corresponding step of the associated method.
