6. The operation system according to claim 5 , wherein the first battery is electrically connected to a first wireless receiving portion via a first regulator.
7. The operation system according to claim 5 , wherein the second battery is electrically connected to a second wireless receiving portion via a second regulator.
8. The operation system according to claim 5 , wherein the third battery is electrically connected to a third wireless receiving portion via a third regulator.
9. An electronic device comprising:
a central processing unit comprising a first battery and a first receiving portion, wherein the first receiving portion has a function of wirelessly charging the first battery;
a display unit comprising a second battery and a second receiving portion, wherein the second receiving portion has a function of wirelessly charging the second battery;
a receiving unit comprising a third battery and a third receiving portion, wherein the third receiving portion comprises a function of wirelessly charging the third battery, and
a power supply management circuit configured to monitor amount of electric power of each of the first battery, the second battery and the third battery,
wherein the power supply management circuit wirelessly charge at least one of the first battery, the second battery, and the third battery with electric power of at least one of the first battery, the second battery, and the third battery.
10. The electronic device according to claim 9 , wherein the first battery is electrically connected to the first receiving portion via a first regulator.
11. The electronic device according to claim 9 , wherein the second battery is electrically connected to the second receiving portion via a second regulator.
12. The electronic device according to claim 9 , wherein the third battery is electrically connected to the third receiving portion via a third regulator.
13. An electronic device comprising:
a control module comprising a central processing unit, a first battery, a first receiving portion, and a first transmitting portion;
a display module comprising a display portion, a second battery, a second receiving portion, and a second transmitting portion;
a communication module comprising a communication circuit, a third battery, a third receiving portion, and a third transmitting portion; and
a power supply management circuit,
wherein the first receiving portion has a function of wirelessly charging the first battery, the second receiving portion has a function of wirelessly charging the second battery, and the third receiving portion has a function of wirelessly charging the third battery, and
