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.

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.
