  We explore the charging of a quantum battery based on spin systems through
periodic modulation of a transverse-field like Ising Hamiltonian. In the
integrable limit, we find that resonance tunneling can lead to a higher
transfer of energy to the battery and better stability of the stored energy at
specific drive frequencies. When the integrability is broken in the presence of
an additional longitudinal field, we find that the effective Floquet
Hamiltonian contains terms which may lead to a global charging of the battery.
However, we do not find any quantum advantage in the charging power, thus
demonstrating that global charging is only a necessary and not sufficient
condition for achieving quantum advantage.
