- the autonomous system comprises at least one battery 1 constituting an energy storage element, an energy generator 2 delivering an intermittent power supply, and a power regulator 3 connected between the generator 2 and the generator 2.
- battery 1 constituting an energy storage element
- the power regulator 3 advantageously comprises not only a power regulation circuit but also a search module of the maximum power point that can be delivered by the generator 2, with a corresponding search algorithm, and a load module of the energy storage element 1 with a dedicated charging algorithm.
- the search and load algorithms can be integrated in the power regulator 3 and / or in a control unit 6.
- Measuring circuits 4 and 5, respectively making it possible to measure the voltage and the current at the output of the generator 2 and at the terminals of the battery 1, are connected to a control unit 6, also connected to the power regulator 3.
- a circuit 7 for measuring the temperature is also connected to the control unit 6 and a charge 8 is conventionally powered by the battery 1.
- the energy generator 2 is, for example, of the wind or microhydraulic type or advantageously a photovoltaic panel.
- the power regulator 3 preferably comprises a BUCK type converter.
- the control unit 6 is thus intended to manage, via the power regulator 3, the match between the power supplied by the generator 2 and the charge of the battery 1.
- the control unit 6 controls the opening and closing of switching elements (not shown) connected between the photovoltaic panel 2 and the battery 1 and intended to allow the disconnection of the battery 1.
- the switching elements are, of preferably integrated into the power regulator 3.
- control unit 6 data relating to load profiles of the battery 1, for determining the theoretical charging power Pthbatt and the theoretical charging voltage Uthbatt as a function of the state of charge and the temperature of the battery 1 , are stored in the control unit 6.
- the circuit 7 advantageously measures the temperature T of the battery 1.
- the autonomous system advantageously comprises a device for communicating with the outside (not shown), which can be integrated in the control unit 6.
- the control unit 6 determines (step F1) the real charge power Pbatt of the battery 1 from the measurements (I / V) of the voltage and the current at the terminals of the battery 1, supplied by the measuring circuit 5. It compares (F2) the actual charge power Pbatt of the battery 1 with a predefined threshold, which is a function of the storage element and which corresponds to the end of charge power, for example 0.1 watt.
- control unit 6 causes (F3) the disconnection of the battery 1 after having stored in memory the last values of voltage and current measured by measuring circuits 4 and 5.
- the control unit 6 then triggers a test protocol to verify that all the elements involved in the charging process of the battery 1 are functional.
- the test protocol notably uses the current and voltage values measured just before disconnecting the battery 1
- the test protocol may begin with (F4) an optional test of the power regulator 3. A particular embodiment of this test will be described in more detail later, with reference to FIG. detecting a faulty operation of the generator and / or the battery 1.
- the control unit 6 calculates the maximum power that can be delivered by the photovoltaic panel 2 Pmpp, on the basis of measurements of the voltage and the current at the terminals of the photovoltaic panel when the latter is set at its maximum power point, with the actual sunshine at the time of the measurements. Measuring these two quantities (voltage and current) requires being able to dissipate or use this power in the system.
- the power electronics is not intended for this type of operation and is therefore not capable of dissipating all the power supplied by the photovoltaic panel 2.
- a first possibility consists in successively measuring the no-load voltage Voc and the short-circuit current of the panel in order to deduce the voltage at the point of maximum power Vmpp and the associated current Impp. To do this, it is necessary to switch quickly from one state to another.
- Another possibility is to make impedance variations and very short measurements, in order to interpolate the point of maximum power.
- the power is high, but the time and therefore the energy are low.
- a number of measurements can be made during switching between the open circuit and the short circuit.
- the control unit 6 can then advantageously compare the open-circuit voltage values Voc and the maximum power point Vmpp with known nominal values. This comparison can, moreover, make it possible to ensure that all the cells of the photovoltaic panel function. If so, the control unit 6 calculates the power Pmpp.

- this step F6 is preferably performed after a predefined waiting period depending on the type, the temperature and the state of charge of the battery, typically the 10 minutes for a lithium battery, after disconnecting the battery. This waiting time allows the battery to stabilize its voltage empty.
- This estimation of the state of charge (SOC) is advantageously used by the control unit 6 to define the desired charging power for various charge profiles of the battery 1.
- the control unit 6 determines, in particular, for the determined state of charge (SOC), the theoretical load power Pthbatt (SOC) as well as the theoretical voltage Uthbatt (T, SOC), which also depends on the temperature of the battery 1, theoretically allowing an optimal load drums.
- the Pthbatt and Uthbatt values used subsequently are therefore functions of the actual state of charge (SOC) of the battery 1 at the moment of their determination (step F6).
- the data relating to load profiles of the battery 1 comprise, preferably, not only the type of battery used and the maximum charge current authorized, but also the charging power and the type of charge depending on the state of charge. drums.
- the control unit 6 uses different quantities measured and determined, to determine the origin of the low load power previously detected (YES output of F2).
- the control unit 6 measures a maximum power Pmpp delivered by the photovoltaic panel 2 of 1OW and a state of charge of the battery 1 of 95%.
- the control unit 6 determines a theoretical Pthbatt load power of 0.1 W.
- the maximum power Pmpp of the photovoltaic panel 2 is then greater than the theoretical power of charge of the battery 1 (Pmpp (10W)> Pthbatt (0.1W)) and the actual charging power Pbatt is equal to the theoretical charging power (0.1 W) of the battery 1.
- the battery 1 is therefore charged .
- the control unit 6 measures a maximum power deliverable by the photovoltaic panel 2 of 1OW and a state of charge of the battery 1 of 70% .
- the control unit 6 determines a theoretical load power Pthbatt of 5W.
- the control unit 6 determines that the charging voltage Ubatt is lower than the theoretical charging voltage Uthbatt.
- the maximum power of the photovoltaic panel 2 is therefore greater than the theoretical load power of the battery 1 (Pmpp (10W)> Pthbatt (0.1 W)), the actual load power is lower than the theoretical load power (Pbatt (0.1 W) ⁇ Pthbatt (5W)).
- the panel 2 is therefore suspected to be defective and the charging algorithm and the search algorithm of the maximum power point (F12) are reset.
- the control unit 6 measures a maximum power deliverable by the photovoltaic panel 2 of 1 W and a state of charge of the battery 1 of 70%.
- the theoretical load power Pthbatt is 5W.
- the maximum power of the photovoltaic panel 2 is therefore less than the theoretical load power of the battery 1 (Pmpp (1W) ⁇ Pthbatt (5W)) and the actual power load is lower than the maximum power of the photovoltaic panel 2 (Pbatt (5W)).
- the charging voltage Ubatt is equal to the theoretical value Uthbatt. Battery 1 is therefore suspected to be degraded and the user is warned (F11).
- the control unit 6 measures a maximum power deliverable by the photovoltaic panel 2 of 0.1 W and a state of charge of the battery 1 70%.
- the theoretical load power Pthbatt is 5W.
- the maximum power of the photovoltaic panel 2 is therefore less than the theoretical power load of the battery 1 (Pmpp (0.1 W) ⁇ Pthbatt (5W)) and the actual power of charge is equal to the maximum power of the photovoltaic panel 2 (0.1 W), This means that the irradiation is weak (F14) and the system is working properly.
- the real load power Pbatt is compared with the smallest of the values representative of the theoretical load power Pthbatt of the energy storage element 1 and the maximum power Pmpp 2. Indeed, if the theoretical load power Pthbatt is lower than the maximum power Pmpp that can be delivered by the generator 2 (output YES of F7), then the actual load power Pbatt is compared with the theoretical load power Pthbatt, in the opposite case (output NO of F7), the actual charging power Pbatt is compared with the maximum power delivered by the generator 2. In addition, the comparison of the charging voltage Ubatt with the theoretical charging voltage Uthbatt n only if the charging power Pbatt is lower than the theoretical charging power Pthbatt and the maximum power Pmpp that can be delivered by the generator 2.
- Resetting an algorithm does not allow generator 2 to be considered defective the first time.
- the generator 2 is reported as defective after a certain number of resets, for example after three resets.
- the controller test may comprise the measurement of the voltage at the terminals of the power regulator 3.
- the measurements of the voltages can be carried out by the measurement circuits. 4 and 5.
- the input voltage of the power regulator corresponds to the voltage at the terminals of the generator Vg and the output voltage of the regulator, Ubatt, is the voltage at the terminals of the storage element. 1.
- the test protocol (F4) of the power regulator 3 can comprise the following steps.
- the control unit 6 has a new measure
- the control unit 6 also makes a new measurement (F16) of the voltage supplied to the battery 1 or uses the value previously stored. The control unit 6 tests (F17) then if the value of the voltage supplied to the battery 1 is zero.
- the same technical problem can be solved in an autonomous system whose power regulator does not include a converter. Since the power converter is an expensive component, it is also possible to charge the battery according to another charging protocol.
- the regulation of the charge of the battery 1 from the generator 2 is then performed by means of the switching elements arranged between the generator 2 and the battery 1.
- the power delivered by the generator is no longer suitable for the charge of the battery, it is no longer possible to vary the input / output ratio.
- the voltages at the terminals of the generator and the battery are identical.
- the generator and the storage element are connected directly via the switching elements.
- the control unit 6 determines (step F21) the actual load current Ibatt of the battery 1 by means of the measuring circuit 5.
- the actual charging voltage is also measured by means of the measuring circuit 4.
- the control unit 6 compares (F22) the actual charging current Ibatt of the battery 1 to a Iseuil predefined first current threshold, preferably equal to the end of charge current which depends directly on the battery (type, dimension, ...) and which is typically equal to 5% of the nominal load current.
- control unit 6 causes (F23) the disconnection of the battery 1 after having stored in memory the last values of measured voltage and current ( Ubatt and Ibatt) by measuring circuits 4 and 5.
- the control unit 6 calculates the voltage Umax and the maximum current Imax delivered by the photovoltaic panel 2, on the basis of measurements of the voltage and the current at the terminals of the photovoltaic panel.
- the maximum values of voltage and current delivered by the generator are independent of each other and correspond to two different operating conditions of the generator, the open-circuit voltage and the short-circuit current.
- the control unit determines the normal operating curve of the generator. This curve is calculated using data specific representative of the generator and which are integrated in the memory of the control unit.
- the operating curve of the generator calculated by the control unit 6 represents the relationship between the delivered current and the voltage across the generator in normal operation. It is observed that in a first domain which corresponds to the lowest voltage values, the deliverable current is substantially maximum and constant, it is the maximum current Imax. Then, as the voltage increases, the current decreases substantially linearly to zero. When the current delivered by the generator is zero, the voltage at the terminals of this same generator is maximum and corresponds to the maximum voltage Umax.
- the operating curve of the generator therefore takes into account current climatic data, for example sunlight (irradiation and temperature).
- control unit 6 determines the state of charge (SOC) of the battery 1 (F25).
- SOC state of charge
- the protocol for determining the state of charge is advantageously identical to that explained above.
- This estimation of the state of charge (SOC) is advantageously used by the control unit 6 to define the desired charge parameters for various charge profiles of the battery 1.
- the electromotive force E of the storage element changes according to the state of charge (SOC) of the battery.
- SOC state of charge
- R of the storage element it is possible to observe small variations in the internal resistance R of the storage element.
- the control unit 6 determines the theoretical load current Ithbatt and the theoretical voltage Uthbatt (T, SOC), which also depends on the temperature of the battery 1.
- This Torque current / theoretical load voltage (Uthbatt / lthbatt) allows, in theory, an optimal charge of the battery.
- the generator and the storage element being in direct connection, the voltage across the storage element and the generator is identical and the current leaving the generator corresponds to the one charging the storage element.
- the operating point must belong to the curves A and B.
- the theoretical load current is therefore always less than Imax and evolves as the battery charge from Imax to the end of charge current for example Iseuil.
- the displacement of the theoretical load current on the The characteristic (U / l) of the generator is a function of the characteristics of the generator and the battery.
- the characteristics of the storage element and the generator are chosen in such a way that the theoretical Ithbatt load current is not less than a limit value, for example 80% of the maximum deliverable current (0.8.lmax). , which corresponds substantially to the point of maximum power deliverable Pmpp by the generator 2.
- This condition links the size of the generator to the size of the battery. If the generator is oversized compared to the previous example (0.8.lmax), the theoretical load current Ithbatt may not be less than 90% of the maximum deliverable current or be substantially equal to the maximum deliverable current Imax.
- this type of assembly can be implemented for charging a lead-acid battery which supports a high current at the end of charging. In the opposite case, if one wants to avoid supplying a high current at the end of charging, the generator is undersized.
- the values Uthbatt and Ithbatt used subsequently are functions of the actual state of charge (SOC) of the battery 1 at the moment of its determination (step F6).
- the control unit 6 uses different measured and determined quantities to determine the origin of the previously detected low charge current (YES output of F22).
- the actual load current Ibatt is compared (F26) with the theoretical load current Ithbatt to check whether the actual load current Ibatt is lower than the theoretical load current (Ibatt ⁇ Ithbatt). If (output NO of F26) the actual load current Ibatt is greater than or equal to the theoretical load current Ithbatt, then the autonomous system is operating normally.
- the state of charge of the battery is then compared to a predetermined end of charge state (F27), for example 99% (SOC ⁇ 99%). If (NO output of F27) the state of charge is greater than or equal to the predetermined end of charge state, the battery is considered charged (F28). In the opposite case (output OUI of F27), the photovoltaic panel 2 limits, a priori, the charge of the battery 1 it means that the irradiation is weak (F29) and that the battery 1 uses all the available current.
- F27 99%
- the theoretical charging voltage Uthbatt is (F30) then compared with the charging voltage Ubatt to verify whether the actual charging voltage Ubbatt is greater than the theoretical charging voltage of the battery 1 (Ubatt> Uthbatt).
