1. A method for distributed battery management of a vehicle, the method comprising:
receiving, at a module management unit associated with a battery cell, a battery cell parameter measurement associated with the battery cell, wherein the module management unit in is communication with a battery radio frequency module via a first link;
performing, by the module management unit, a first function based at least in part on the battery cell parameter measurement to generate a first signal, wherein the first function comprises performing a calculation on the battery cell parameter measurement;
transmitting, from the module management unit, the first signal to the battery radio frequency module via the first link;
performing, by the battery radio frequency module, a second function based at least in part on the first signal to generate a second signal;
transmitting, from the battery radio frequency module, the second signal to a controller; and
performing, by the controller, a third function based at least in part on the second signal.
