  We present a scheme for the charging of a quantum battery based on the
dynamics of an open quantum system undergoing coherent quantum squeezing and
affected by an incoherent squeezed thermal bath. We show that quantum
coherence, as instigated by the application of coherent squeezing, are key in
the determination of the performance of the charging process, which is
efficiency-enhanced at low environmental temperature and under a strong
squeezed driving.
