contents 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 the complete charging is achieved through the application of two sequential pulses, while in the second the charging occurs in a unique step applying the two pulses simultaneously. Both protocols are analytically solvable leading to a complete control on the dynamics of the quantum system. According to this it is possible to determine that the latter approach is characterized by a shorter charging time, and consequently by a greater charging power. We have then tested these protocols on IBM quantum devices based on superconducting circuits in the transmon regime. The minimum achieved charging time represents the fastest stable charging reported so far in solid state quantum batteries.
