  The storage and transfer of energy through quantum batteries (QBs) are key
elements in quantum networks. Here, we propose a QB design based on
transitionless quantum driving (TQD), which allows for inherent control over
the battery charging time, with the speed of charging coming at the cost of the
internal energy available to implement the dynamics. Moreover, the TQD-based QB
is also shown to be locally stable, which means that the QB can be disconnected
from a consumption hub (CH) at any time after the energy transfer to the CH,
with no fully energy backflow to the QB. This provides a highly charged CH in
an always-on asymptotic regime. We illustrate the robustness of the CH charge
against time fluctuations and the full control over the evolution time for a
feasible TQD-based QB.
