Abstract

A wireless rechargeable battery includes a housing, a circuit module, an energy storage unit, and a plurality of electrodes. The wireless rechargeable battery is adapted to be disposed on a wireless charging device to be wirelessly charged. The circuit module includes a receiving unit and a power management unit. The receiving unit is disposed in the housing and adapted to receive electric energy from the wireless charging device. The power management unit is disposed in the housing and electrically coupled to the receiving unit. The energy storage unit is disposed in the housing and electrically coupled to the power management unit. The electric energy is adapted to be inputted to the energy storage unit via the power management unit. The electrodes are disposed on the housing and electrically coupled to the power management unit. The electric energy is adapted to be outputted to the electrodes via the power management unit.
