Abstract
Provided battery systems include a plurality of battery electronic control units, each associated with a battery pack of a plurality of battery packs. Each battery electronic control unit is adapted to acquire analog current measurements of the associated battery pack and to convert the acquired analog current measurements to a digital value such that the plurality of battery electronic control units produce a plurality of digital values. The system may sum the digital values, or may process pulse-width modulated signals, analog signals and so forth. A battery system electronic control unit is adapted to receive and monitor the plurality of digital values and to determine a total battery system current value based on the received plurality of digital values.
