1. A battery management system for an electric aircraft, the system comprising:
a control circuit communicatively connected to a plurality of sensors configured to detect a plurality of measurement data related to a battery pack, wherein the control circuit is configured to:
identify a state transition criterion as a function of an operating condition of the battery pack; and transition from a first state and a second state as a function of the state transition criterion, wherein the control circuit is configured to:
perform a first function including:
operate at a first duty cycle and communicate with a first subset of the plurality of sensors in the first state; and
operate at a second duty cycle and communicate with a second subset of the plurality of sensors in the second state, wherein: the second subset is different from the first subset and includes fewer sensors than the first subset, and the second duty cycle is distinct from the first duty cycle; or
perform a second function including:
transition from a second state and a third state upon identifying a second state transition criterion;
wherein the control circuit is configured to operate at a third duty cycle and communicates with a third subset of the plurality of sensors in the third state, wherein the third duty cycle is distinct from the second duty cycle.
