an extracorporeal processor (201) of the extracorporeal machine (200) is wirelessly coupled with the first coil (12) and/or the second coil (31) through a third coil (202).

10. The brain neuromodulator as in claim 9, wherein,

when the third coil (202) is simultaneously wirelessly coupled with the first coil (12) and the second coil (31), the first coil (12) is wirelessly decoupled from the second coil (31), and the external machine (200) charges the battery (11) while supplying power to the internal machine (3);

when the third coil (202) is only wirelessly coupled with the first coil (12), the external machine (200) charges the battery (11) and is wirelessly coupled with the second coil (31) through the first coil (12), so that the battery (11) supplies power to the internal machine (3);

-the external machine (200) supplies power to the internal machine (3) when the third coil (202) is coupled wirelessly with only the second coil (31);

when the third coil (202) is disconnected from wireless coupling, the first coil (12) and the second coil (31) are wirelessly coupled, so that the battery (11) can supply power to the internal machine (3).

11. A method of operating a brain neuromodulator as claimed in claim 10, comprising the following modes of operation:

in the first working mode, the internal body machine (3) works, and power is supplied to the internal body machine (3) by the battery (11) preferentially;

in the second working mode, when the internal body machine (3) works and the battery (11) does not work, the external body machine (200) supplies power to the internal body machine (3);

in the third working mode, when the internal machine (3) works and the electric quantity of the battery (11) is insufficient, the external machine (200) supplies power to the internal machine (3) and simultaneously charges the battery (11);

in the fourth working mode, when the internal machine (3) does not work and the electric quantity of the battery (11) is insufficient, the battery (11) is charged through the external machine (200);

and in a fifth working mode, when the internal body machine (3) does not work and the service life of the battery (11) is insufficient, the independent power supply unit (1) is replaced from the implant (100).
