A vehicle-mounted charger fault rapid protection system, comprising a PFC power circuit, a high-voltage bus capacitor, a bridge-type isolation conversion power circuit, a PFC controller and a bridge-type circuit controller. The PFC power circuit is separately connected to the high-voltage bus capacitor and the PFC controller. The bridge-type isolation conversion power circuit is separately connected to the high-voltage bus capacitor and the bridge-type circuit controller. The bridge-type circuit controller is connected to the PFC controller by means of a hardwired channel. The PFC controller judges, according to a sampled signal, whether the PFC power circuit has an abnormal state causing circuit failure, and if so, outputs a fault protection signal and inputs the fault protection signal into the bridge-type circuit controller by means of the hardwired channel. The bridge-type circuit controller stops output of the bridge-type isolation conversion power circuit when detecting the fault protection signal output by the PFC controller. Also provided are a method and a vehicle adopting the protection system. By adopting the system, rapid protection can be carried out when a fault occurs in a charger.
