Motivated by recent experimental observations carried out in superconducting transmon circuits, we compare two different charging protocols for three-level quantum batteries based on time-dependent classical pulses. In the first case, complete is achieved through application of sequential pulses, while second occurs a unique step applying pulses simultaneously. The latter approach characterized shorter time, and consequently greater power. Moreover, both are analytically solvable, leading to control dynamics system opening perspectives manipulation so-called qutrits. To support this analysis, have tested IBM devices circuits regime. minimum time represents one fastest stable reported so far solid-state batteries. Published American Physical Society 2024
