1. A monitor module to monitor a battery stack having multiple cells connected in series, comprising:

  • sampling circuits to sample cell voltages of corresponding cells of at least a subset of the cells of the battery stack;

    a readout circuit to receive the sampled cell voltages of the corresponding cells of the subset of cells and to provide at least one readout signal that represents the sampled cell voltages; and

    a module control unit to provide simultaneous sample commands to the sampling circuits and to provide sequential read commands to the sampling circuits, in response to control signals.
