Quantum batteries represent a new and promising technological application of quantum mechanics, offering the potential for enhanced energy storage fast charging. In this work, we study battery composed three two-level systems with XXZ coupling operating under open boundary conditions. We investigate role played by ferromagnetic antiferromagnetic initial configurations on charging dynamics battery. Two mechanisms are explored: static charging, where interacts constant classical external field, harmonic field oscillates periodically over time. Our results demonstrate that can be more efficient in case, achieving maximum due to complete population inversion between ground excited states. contrast, excels case. By analyzing stored average power these two regimes, highlight impact anisotropy performance batteries. findings provide valuable insights optimizing based system’s state configuration, paving way devices storage.
