The invention discloses a vehicle-mounted end parallel protection circuit applicable to an LCL/ LCC topology wireless charging system, and belongs to the technical field of wireless charging and safecharging of electric automobiles. The protection circuit comprises a voltage sensor, a current sensor, a protection control circuit and a relay, wherein a normally-opened relay is connected in parallel with the output end of an LCL/ LCC topology; the protection control circuit is used for determining whether overvoltage or overcurrent occurs in the charging process based on the acquired vehicle-mounted electric charging voltage and the charging current so as to control the switching state of the relay; and moreover, the protection control circuit further comprises a wireless communication module for sending an instruction of starting or stopping power supplying to a power supply at the ground. The protection circuit is applicable to a wireless charging system needing quick protection response; in case of abnormal conditions such as overcurrent and overvoltage in the charging process of the electric automobile, the protection is carried out timely, so that the safety of the whole systemis ensured; and the protection circuit is low in input cost, high in reliability of a control method, and high in practicability.
