  The Su-Schrieffer-Heeger (SSH) model has recently received considerable
attention in condensed matter because it describes a typical one-dimensional
system with topological edge states. Here, we investigate SSH-based charging
protocols of quantum batteries (QB) with N quantum cells. This SSH QB hopping
interaction induced ground state splitting makes the different effects of the
dimerize parameter to the QB in the different quantum phase region. In the
non-splitting region, the dimerize parameter has little influence on the QB.
Whereas the fully-splitting region, the dimerize parameter has a significantly
quantum advantage to the energy and ergotropy in the ground state fully
splitting region, which leads the dimerize spin couples will have larger
occupations than other spins. Although we have enhanced energy and ergotropy by
the dimerize parameter, QB's capacity will decrease.
