Claim 14:
15. A terminal comprising:
a workload circuit;
an alternating current/direct current conversion circuit coupled to the workload circuit and comprising an input end;
a coil system coupled to the input end and comprising:
a first insulation layer comprising:
a first side; and
a second side;

a first coil winding located on the first side and comprising:
a second insulation layer comprising:
a third side; and
a fourth side; and

a plurality of first coils comprising:
a first part located on the third side and comprising a first segment of a first conducting wire, wherein the first segment comprises N first cutting openings that extend along a first extension direction of the first segment and are configured to divide the first segment into N+1 first sub conducting wires; and
a second part located on the fourth side and comprising a second segment of the first conducting wire, wherein the second segment comprises N second cutting openings that extend along a second extension direction of the second segment and are configured to divide the second segment into N+1 second sub conducting wires; and

a second coil winding located on the second side and comprising:
a third insulation layer comprising:
a fifth side; and
a sixth side; and

a plurality of second coils comprising:
a third part located on the fifth side and comprising a third segment of a second conducting wire, wherein the third segment comprises N third cutting openings that extend along a third extension direction of the third segment and are configured to divide the third segment into N+1 third sub conducting wires; and
a fourth part located on the sixth side comprising a fourth segment of the second conducting wire, wherein the fourth segment comprises N fourth cutting openings that extend along a fourth extension direction of the fourth segment and are configured to divide the fourth segment into N+1 fourth sub conducting wires,
wherein N is an integer greater than or equal to 1,
wherein the N+1 first sub conducting wires and the N+1 second sub conducting wires are electrically coupled in a one-to-one manner to form a plurality of N+1 pairs of fifth sub conducting wires comprising a first crossover structure,
wherein the N+1 third sub conducting wires and the N+1 fourth sub conducting wires are electrically coupled in a one-to-one manner to form a plurality of N+1 pairs of sixth sub conducting wires comprising a second crossover structure, and

wherein the coil system is configured to:
receive an alternating-current signal; and
transmit the alternating-current signal to the alternating current/direct current conversion circuit; and

a charging control system coupled to the alternating current/direct current conversion circuit and configured to control the alternating current/direct current conversion circuit to:
convert the alternating-current signal into a direct-current signal; and
output the direct-current signal to the workload circuit.
