1. A cell apparatus which emits and receives AC power via magnetic field resonance coupling to an external device, comprising:
- a cell interface to interface with a cell;
a first circuit to generate, in a discharging mode, a magnetic field to induce an AC current in the external device, and to generate, in a charging mode, an AC current from a magnetic field received from the external device;
a conversion circuit to generate, in the charging mode, a charge signal from the AC current generated in the first circuit, the conversion circuit supplying the charge signal to the cell interface; and
a frequency generator to generate, in the discharging mode, an AC current from a discharge signal received from the cell interface, the frequency generator supplying the AC current to the first circuit.

Abstract
A cell apparatus that emits and receives AC power via magnetic field resonance includes a cell interface and a circuit to generate a magnetic field when emitting the AC power and to generate an AC current when exposed to a magnetic field from an external device. The cell apparatus also includes a switch or sensor to determine whether a charging mode or a discharging mode is active. Because the cell apparatus emits and receives AC power via magnetic field resonance, it can be charged and discharge without electrical contact with another device.
