Battery power source control and current detection systems and methods

The battery system of claim 8, wherein the clock generator is further configured to generate a second sample speed at which the plurality of battery electronic control units convert the acquired analog current measurements into the digital values.

A battery system, comprising:

• a plurality of slave electronic control units, each associated with a battery pack of a plurality of battery packs and configured to monitor and control the associated battery pack;
• and
• a master electronic control unit associated with a master battery pack of the plurality of battery packs and coupled to each of the plurality of slave electronic control units, wherein the master electronic control unit is configured to determine, based on a received system control signal, a subset of the plurality of slave electronic control units that are not to receive power, and to selectively electronically decouple the subset of the plurality of slave electronic control units from the master electronic control unit.

A battery system, comprising:

• a plurality of battery electronic control units, each associated with a battery pack of a plurality of battery packs, wherein each battery electronic control unit is configured 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;
• and
• a battery system electronic control unit configured 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.
