The invention discloses a power battery pack high-voltage-resistant high-temperature-resistant flame-retardant insulating safety protection cover and a manufacturing method thereof. A protection coverhousing is a square housing; the housing is mounted at the front part of a battery rack at one side of a BMS (battery management system) at the front end of a battery module and covers a high-voltagelarge-current control component; latticed reinforcing ribs are arranged on the inner walls of the housing on the front side, the rear side, the left side, the right side and the upper side; an avoidance notch I of a positive plug connector or a negative plug connector is formed in the bottom of the housing in the center of the front side; avoiding gaps are formed in the bottoms of the front housing and the rear housing at the end part of the housing on one side of an automatic controller, and the height of the avoiding gap in the front housing is greater than that of the negative plug connector or the positive plug connector; a cable avoiding notch II is formed in the housing at the rear avoiding gap; and a cable avoiding notch III is formed in the rear housing at the other end part of the housing. The protection cover housing is formed by adding a 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane, light calcium carbonate and a flame retardant aluminum hydroxide into high polymer material methyl vinyl silicone rubber, carrying out mixing, and carrying out extrusion molding in a mold at high temperature and high pressure.
