The invention provides a power battery high-voltage monitoring protection system and protection method. The power battery high-voltage monitoring protection system comprises a battery management unit and a monitoring protection system, the monitoring protection system communicates with the battery management unit through a first communication mode and a second communication mode, and the first communication mode and the second communication mode comprise hard wire communication; the whole vehicle collision system communicates with the battery management unit, and the whole vehicle collision system is used for monitoring whether the vehicle collides or not; and the trigger type fusing system communicates with the monitoring protection system, and the trigger type fusing system is used for cutting off the high voltage output by the battery pack. According to the technical scheme, the communication between the battery management unit and the monitoring protection system is more stable in a redundant communication mode, the problem that communication is prone to interference in the prior art is solved, and the high-voltage monitoring protection system can effectively avoid the safety problem caused by vehicle collision.
