1. A coil unit for inductively charging a vehicle, comprising:
a coil, wherein the coil comprises a plurality of windings of at least two electrical lines, wherein
the at least two electrical lines are connected in parallel,
each of the at least two electrical lines has a respective winding part and an additional part in which an additional inductance unit is arranged that has a prescribed electrical inductance that is 0.02 times, 0.04 times, 0.06 times, or 0.08 times an electrical inductance of each of the at least two electrical lines in the respective winding part,
the at least two electrical lines are litz wires, and
the additional inductance units of the at least two electrical lines have a common ferrite, but are oppositely wound.
