Abstract
Rechargeable battery assemblies and methods of constructing rechargeable battery assemblies are provided. Rechargeable battery assemblies can include a storage cell and receive circuitry comprising a receive coil operatively connected to receive control circuitry, the receive coil configured to receive inductively coupled current, the receive control circuitry configured to rectify the current and communicate charging power to the storage cell, the coil wound around a shield/core comprising magnetically permeable material, and the shield/core disposed around the storage cell. Methods of constructing rechargeable battery assemblies can include disposing a shield/core comprising magnetically permeable material around a storage cell; winding a receive coil around the shield/core; and providing the receive coil in operative connection with receive control circuitry and the storage cell, the receive coil configured to receive inductively coupled current, and the receive control circuitry configured to rectify the current and communicate charging power to the storage cell.
