Energy efficiency characterization involves the dynamic real-time measurement and analysis of the waveform and AC/DC power consumed by a system or subsystem of a functional device. This precise characterization method allows for the evaluation of a device's energy consumption during operation, aiming to optimize its performance in terms of energy consumption if necessary. Simultaneously, the behavior of a power source (such as a battery or cell) is evaluated based on a recorded power consumption profile, which enables the determination of the performance and lifespan of the power source under various usage conditions.
