Abstract
Methods and systems are provided for encoding vehicle data comprising a first voltage pertaining to a first battery cell and a second voltage pertaining to a second battery cell is provided. A determination is made as to whether the first voltage is valid. In addition, a determination is made as to whether the second voltage is valid. One of a plurality of values is assigned to a validity measure based at least in part on whether the first voltage or the second voltage, or both, are valid. The plurality of values, in binary form, are at least two bit errors removed from one another.
