Abstract
A storage apparatus includes a plurality of storage cells connected in series. Each storage cell comprises a storage element that stores a charge, a container that houses the storage element, a reception antenna capable of receiving power transmitted from a transmission antenna of a feeding facility provided in a wireless power transfer system, and a charging control circuit that charges the storage element using the power received by the reception antenna. The plurality of storage cells are charged concurrently and wirelessly, and therefore charging can be performed on all of the storage cells without overcharging or undercharging.
