Abstract
Various apparatuses and methods for detecting cell connection status of a multi-cell battery are disclosed herein. For example, some embodiments provide an apparatus for detecting cell connection status of a multi-cell battery. The apparatus includes a battery cell input for each cell, a cell connection status detector for each cell, and at least one comparator. Each of the cell connection status detectors is connected to a battery cell input and has a current-based status indicator output. The at least one comparator is connected to the current-based status indicator outputs. Each of the plurality of cell connection status detectors floats in a different supply voltage range. The at least one comparator is referenced to a lower voltage potential than at least one of the plurality of cell connection status detectors.
