The invention discloses a clock spring, a steering system and an electric vehicle. The clock spring comprises a rotor and a stator. The rotor is used for being fixedly arranged on a driving rotating shaft and comprises a rotor shell, a contact assembly and a first wireless communication module, wherein a first containing space is formed in the rotor shell, and the first wireless communication module is installed in the first containing space. The stator is used for being fixedly arranged on a steering driving module and comprises a stator shell, an annular resistor and a second wireless communication module, a second containing space is formed in the stator shell, and the second wireless communication module is installed in the second containing space. The first wireless communication module is in wireless communication connection with the second wireless communication module; along with the rotation of the steering arm, the conductive contact can slide on the annular resistor; a resistor between one end of the opening and the conductive contact is used for determining the turning angle of the steering arm. The clock spring provided by the invention avoids wire harness winding, and has a wheel rotation angle measurement function at the same time.
