1. A method of operating a battery management system processor to achieve voltage balancing, wherein the battery management system processor comprises a data communications circuit connected to a power output terminal of a battery pack, and wherein the battery management processor performs the following steps:
i) obtaining cell voltage, cell current, cell temperature and cell fuse status data for each of a plurality of battery cells by transmitting and receiving via the data communications circuit,
ii) determining desired cell output voltages based on the cell voltage, cell current, cell temperature for each of the plurality of battery cells, and
iii) transmitting desired cell output voltage data to the data communications circuit of each of the plurality of battery cells using the data communications circuit of the battery management system processor; and
wherein the battery management system processor operates to reduce higher cell voltages to match those of lower voltage cells in the battery pack to prevent damage.
