Abstract

A battery pack is provided which includes an antenna coil for generating a magnetic field, a battery cell and a positive pole terminal and a negative pole terminal electrically connected with the battery cell, wherein a resultant of superimposing current from the battery cell or current to the battery cell and a signal from the antenna coil or a signal to the battery is sent from the positive pole terminal or the negative pole terminal, or received from the positive pole terminal or the negative pole terminal.

Claims

1. A battery pack comprising:

an antenna coil for generating a magnetic field;

a battery cell; and

a positive pole terminal and a negative pole terminal electrically connected with the battery cell, wherein

a resultant of superimposing current from the battery cell or current to the battery cell and a signal from the antenna coil or a signal to the battery is sent from the positive pole terminal or the negative pole terminal, or received from the positive pole terminal or the negative pole terminal.

2. The battery pack according to claim 1, further comprising a resonance circuit for determining a resonance frequency between the antenna coil and the positive pole terminal or the negative pole terminal.

3. The battery pack according to claim 1, wherein a high pass filter is arranged between the antenna coil and the positive pole terminal or the negative pole terminal.

4. The battery pack according to claim 1, wherein a low pass filter is arranged between the battery cell and the positive pole terminal or the negative pole terminal.

5. The battery pack according to claim 1, wherein the antenna coil and the battery cell have a stacked structure in which a magnetic body sheet is sandwiched in between.

6. An information processing apparatus comprising:

a battery pack; and

an information processing apparatus main body for receiving power supply from the battery pack, wherein

the battery pack includes,

an antenna coil for generating a magnetic field,

a battery cell,

a positive pole terminal and a negative pole terminal electrically connected with the battery cell, and

a resultant of superimposing current from the battery cell or current to the battery cell and a signal from the antenna coil or a signal to the battery is sent to the information processing apparatus main body through the positive pole terminal or the negative pole terminal, or received from the information processing apparatus main body through the positive pole terminal or the negative pole terminal.

7. The information processing apparatus according to claim 6, wherein a resonance circuit for determining a resonance frequency is arranged in either the battery pack or the information processing apparatus main body.

8. The information processing apparatus according to claim 7, wherein the resonance circuit is arranged between the antenna coil and the positive pole terminal or the negative pole terminal.

9. The information processing apparatus according to claim 6, wherein a high pass filter is arranged between the antenna coil and the positive pole terminal or the negative pole terminal.

10. The information processing apparatus according to claim 6, wherein a low pass filter is arranged between the battery cell and the positive pole terminal or the negative pole terminal.

11. The information processing apparatus according to claim 6, wherein the antenna coil and the battery cell have a stacked structure in which a magnetic body sheet is sandwiched in between.
