A system for wirelessly charging an electrical energy storage device such as secondary electrochemical cell or battery pack of at least two electrically connected secondary cells is described. The system comprises an electrical energy capture circuit and capture coil that is electrically incorporatable with an energy storage device. The system is primarily designed to be used with electrical power that is wirelessly transmitted by near field magnetic induction. The energy transmitting circuit and coil may be incorporated within a container designed to hold or enclose an energy storage device during an autoclave sterilization process. In addition, a wireless energy adapter configured with the energy capture circuit designed to facilitate wireless charging of an energy storage device is disclosed. Furthermore, a cart designed to provide a mobile wireless energy source is disclosed. The cart comprises at least one of the energy transmitting circuit, transmitting coil, energy capture circuit, and energy capture coil.
