1. An energy storage system comprising:
a stack of battery modules;
a plurality of ultrasound emitter transducers, each ultrasound emitter transducer acoustically coupled to a surface of a respective one of the battery modules;
a plurality of ultrasound receiving transducers, each ultrasound receiving transducer acoustically coupled to a surface of a respective one of the battery modules;
one or more excitation modules electrically interfaced with the plurality of ultrasound emitter transducers;
one or more capture modules electrically interfaced with the plurality of ultrasound receiving transducers; and
an ultrasound battery management system controller configured to initiate battery module ultrasound interrogation sequences,
wherein the stack of battery modules is connected in series with a power exchange module, and the stack of battery modules is configured to be charged or discharged during the ultrasound interrogation sequences.
