Abstract: The invention relates to a method for electrically characterising the cells of a photovoltaic module. Said method comprises measuring (MES) the light intensity emitted by electro luminescence by each of the cells according to a voltage applied to the module. Said method further comprises determining (RI), based on the measurements of the light intensity emitted by electroluminescence by each of the cells in a first voltage range applied to the module, hierarchical relationships of analytical relationships between first characteristic electrical parameters of the cells. Said method further comprises determining (R2), based on the measurements of the light intensity emitted by electroluminescence by each of the cells in a second voltage range applied to the module, hierarchical relationships of analytical relationships between second characteristic electrical parameters of the cells.

Abstract: A process for maximum power point tracking of a photovoltaic module, which includes monitoring the module's degradation by: for a periodicity n1δt0 with n1>1 constant or variable, steps of measuring parameters I and V of the module for points offset in voltage voltage VMPP+α and VMPP−β over the curve I(V) relative to the maximum power point MPP, calculating the slope dI/dV+ at the point VMPP+α and the slope dI/dV− at the point and VMPP−β and recording of the data with the MPP; for a periodicity n2δt0 with n2≥n1 of > of steps of measuring values I and V by sweeping the curve I(V) and calculating and storing the module's parameters and values; one or several steps of calculating, tracing and displaying of (p/2)
curves of data pairs based on p measured and calculated parameters; and one or more steps of detecting degradation from the measured and calculated parameters.

Abstract: The present invention relates to a method for detecting, by ultrasound, defects in a material (MS), comprising the steps of transmitting, by M transmitters of index i, and receiving, at sampling times n.Te, by means of M receivers of index j, signals x(n, i, j), forming a sampling matrix (AΔ) having N columns Yn formed by the signals x(n, i, j) for which a distance between the receiver of index j and the transmitter of index i is equal to the deviation Δ and rows Xi,j formed by the signals x(n, i, j), the pair i, j being different from one row Xi,j to the next, calculating a covariance matrix (CΔ) for the projections Xi,jproj,k of the rows Xi,j of the matrix (AΔ) on the K eigenvectors (Vk) corresponding to the K largest eigenvalues (λk), subtracting, from each row Xi,j, the K projections Xi,jproj,k to obtain residual measurement signals x*(n, i, j) for detecting defects.

Abstract: A method of constructing a chart of correlations between a rapid discharge and a slow discharge in order to measure the wear of at least one electrochemical cell, including a measurement phase that includes a training sequence followed by a characterization sequence, and an aging phase. Each of the sequences includes charging-relaxing-discharging-relaxing under controlled conditions and is repeated with different conditions. The time of each discharge is measured. The aging phase includes an alternation of charges and discharges with no intermediate relaxation and is implemented before each repetition of the measurement phase, such that a real capacity is obtained for a plurality of pairs of imposed parameters.

Abstract: In the management of a facility pumping water from a natural environment containing impurities, the facility makes use of at least one rotary filter purifying the pumped water while some impurities at least partially clog the rotary filter. In particular, provision is made for estimating an evolution over time of a pressure loss caused by impurities clogging the rotary filter, based at least on data relating to the natural environment, dimensions of the rotary filter, and local measurements relating to at least one water level Namont upstream of the filter and to a flow rate of water Qaspiré drawn in downstream of the filter. Such an estimate of the evolution over time of the pressure loss makes it possible to anticipate possible risks of insufficient water supply to the pumping system (POM) downstream of the filter (FIL), or even to design filters (FIL) adapted to the needs of specific pumping facilities.
