Abstract: An accumulator battery system includes series-connected accumulators with potentials across stages powering corresponding controllers that measure potential differences between terminals of accumulators. A first analog-to-digital converter encodes the potential measured between terminals of an accumulator. A first output delivers a first digital sequence corresponding to the encoded potential difference, logic levels of which are defined by at least two potentials across the first-stage accumulator terminals. A decoder decodes a potential measured by the first control-device from the first digital sequence. A second analog-to-digital converter selectively encodes a potential difference measured between terminals of a second-stage accumulator of the second stage and two potentials of the digital sequence received on the input. A second control-device processor extrapolates a potential difference across the first-stage accumulator terminal of the first stage based on two potentials of the received digital sequence.

Abstract: Methods, apparatuses, and non-transitory computer readable storage media for a smart tutorial that adapts are described. The smart tutorial may assist in the operation of a vehicle including generating a situational profile that includes driver identity data, vehicle state data, or extra-vehicular state data. The situational profile is compared to assistance profiles that include aggregate identity data, aggregate vehicular state data, or aggregate extra-vehicular state data. The assistance profiles correspond to assistance instructions. Based on the comparison, similarity values corresponding to the assistance profiles are generated based on the comparison between the situational profile and the assistance profiles. The greatest similarity value corresponds to the assistance profile that is most similar to the situational profile. In response to the usage frequency value exceeding a usage frequency threshold value, the assistance instruction that corresponds to the assistance profile that is most similar to the situational profile may be selected.
