The invention discloses a fast charging protection device, a vehicle and a fast charging protection control method.The fast charging protection device comprises a connecting module, a load module, a power module and a power management system, the connecting module is used for being connected with a voltage regulating module of a charging pile to form a current path, and the load module comprises a load switch assembly and a high-voltage load; the load switch assembly is electrically connected with the connecting module, the power supply module is electrically connected with the connecting module, and the power supply management system is electrically connected with the connecting module, the load module and the power supply module. Thus, under the condition that the collected target voltage output by the voltage regulating module of the charging pile is within the preset range, the power management control system controls the quick charging loop to be switched on, the pre-charging circuit is switched off, and the load switch assembly is switched on. The device damage caused by the quality problem of the charging pile or the output abnormity in the voltage regulation stage of the charging pile during quick charging can be prevented, and then the safety in the quick charging process of the electric vehicle is improved.
