Abstract: An embodiment processing system comprises terminals configured to be connected to cells of a rechargeable battery to receive cell voltages, a digital processing circuit, a serial communication interface and a transmission queue interfacing the digital processing circuit with the serial communication interface for parallel operation. The digital processing circuit synchronously acquires a given number of digital samples of each of the cell voltages and stores them to a memory. The digital processing circuit encodes the digital samples stored to the memory via a data compression module, and stores the encoded data to the transmission queue. For example, the data compression module may generate the encoded data by subtracting a given offset from each digital sample to generate values indicative of the dynamic variation of each sample with respect to the offset, and removing a given number of most significant bits from each value.
