A method for determining an average value of a periodic or quasi-periodic voltage signal that can be transmitted on a communication bus with a transmission period greater than the period of the signal. The method includes acquiring measurements of the signal with a measurement period corresponding to the transmission period of the average value on the bus, obtaining the average value from the acquired measurements, applying, for each measurement, a variable delay, defining a time of measurement within the measurement period, relative to a reference time, and obtaining the average value from the result of the measurement made at each time of measurement and from the results of the measurements made previously.

Method for determining the average value of a periodic or quasi-periodic voltage signal

A method for determining, by sampling at a given frequency, a maximum voltage value of a load signal of at least one motor vehicle battery cell, the load signal to be sampled being rectified and sinusoidal and having a frequency that is higher than the sampling frequency, the method including: determining a sampling frequency, a measurement time at the sampling frequency, and a related inaccuracy, measuring a load voltage with the predetermined sampling frequency and with the predetermined measurement time, and determining a maximum load voltage.
