A quantum battery is considered as a one-dimensional spin-1/2 chain, which can be described by the $XY$ Heisenberg Hamiltonian. An external magnetic field is applied to charge the quantum battery. The results demonstrate that the counterrotating-wave terms play an important role in the performance of the quantum battery, including enhancing the maximum stored energy and charging power, and improving the charging precision. Some quasimomentum canonical modes play an important role in the charging process. The analytical expressions of the maximum stored energy, charging power, and charging precision are derived. Especially, for the pure counterrotating-wave terms, the “behavior” expressions can be employed to obtain the optimal values of the parameters. This study provides a potential way to design high stored energy and fast charging quantum batteries.
