Abstract
In an embodiment, an apparatus is disclosed that includes a first battery management circuit. The first battery management circuit is configured to measure a voltage of a first battery cell of a battery pack and to generate a first voltage measurement based at least in part on the measured voltage of the first battery cell. The first battery management circuit is configured to receive a bit of a first response from a second battery management circuit. The bit of the first response is generated by the second battery management circuit based at least in part on a measured voltage of a second battery cell of the battery pack. The first battery management circuit is configured to sum the bit of the first response with a corresponding bit of the first voltage measurement and to provide the summed bit to a third battery management circuit as part of a second response.
