The invention discloses a fault protection method and device of an electric automobile quick charging station. The method includes the steps that a fault feature of a fault structural point of the electric automobile quick charging station is obtained; a protection strategy is configured for the fault structural point according to the obtained fault feature; and according to the configured protection strategy, fault protection is conducted on the fault structural point of the electric automobile quick charging station. By the adoption of the method and device, the technical problem that the requirement for charging station fault protection cannot be met when fault protection conducted on the charging station only depends on single relay protection in the correlation technique is solved.
