Abstract

A wireless charging jacket combined with a battery includes an induction coil, a control circuit, an isolation gasket, at least one conductive terminal, and a package material. The induction coil transforms an electromagnetic wave into an electrical energy. The control circuit performs a wireless charging operation upon the battery by using the electrical energy transformed by the induction coil. The isolation gasket is used for isolating the electromagnetic wave. The conductive terminal is coupled to the control circuit, wherein the wireless charging jacket performs the wireless charging operation upon the battery via the conductive terminal. The package material at least partially covers the battery, such that the battery is installed in the wireless charging jacket. The induction coil, the control circuit, the isolation gasket, and the conductive terminal are disposed on the package material.
