Disclosed is a battery pack case assembly for an electric or hybrid vehicle. The battery pack case assembly includes a case body and a cover. The case body receives a battery pack, and the cover is coupled to the case body. The case body is formed of a plastic composite in which a long fiber or a blend of a long fiber and a continuous fiber is used as a reinforcing fiber in a plastic matrix. A separate reinforced member is bonded to both side bracket parts for coupling to a vehicle body, and is formed of a plastic composite in which a long fiber, a continuous, or a blend of a long fiber and a continuous fiber is used as the reinforcing fiber in the plastic matrix.

1. A battery pack case assembly for an electric vehicle, comprising: a case body for housing a battery pack;a cover removably coupled to the case body,wherein the case body is formed of a plastic composite in which a long fiber or a blend of a long fiber and a continuous fiber is used as a reinforci
1. A battery pack case assembly for an electric vehicle, comprising: a case body for housing a battery pack;a cover removably coupled to the case body,wherein the case body is formed of a plastic composite in which a long fiber or a blend of a long fiber and a continuous fiber is used as a reinforcing fiber in a plastic matrix, anda first separate reinforced member including at least two brackets each bonded to a side of the case body, the separate reinforced member formed of a plastic composite in which a long fiber, a continuous fiber, or a blend of a long fiber and a continuous fiber is used as the reinforcing fiber in a plastic matrix, anda second separate reinforced member having a planar shape being disposed at a bottom of the case body connecting the at least two brackets in the first separate reinforced and disposed perpendicularly planar to the bottom of the case body, wherein the second separate reinforced member disposed at the bottom of the case body is formed of a plastic composite comprising a continuous fiber as a reinforcing fiber in a plastic matrix,wherein the case body is integrally formed with the second separate reinforced member by an extrusion-compression molding apparatus and the bottom of the case body is formed in a single layer structure. 2. The battery pack case assembly of claim 1, wherein the long fiber of the case body and the long fiber of the first separate reinforced member both have an aspect ratio of about 1,000. 3. The battery pack case assembly of claim 1, wherein the long fiber of the case body and the long fiber of the first separate reinforced member both have an aspect ratio of about 1,000 to about 10,000. 4. The battery pack case assembly of claim 1, wherein the plastic matrix of the both the first and second separate reinforced member is selected from the group consisting of: Polypropylene (PP), Polyamide (PA), Polyether Ether Ketone (PEEK), Polycarbonate (PC), Polyphenylene Sulfone (PPS), Polyphenylene Ether (PPE), Thermoplastic Polyurethane (TPU), and combinations thereof. 5. The battery pack case assembly of claim 1, wherein the plastic matrix of the case body is selected from the group consisting of Polypropylene (PP), Polyamide (PA), Polyether Ether Ketone (PEEK), Polycarbonate (PC), Polyphenylene Sulfone (PPS), Polyphenylene Ether (PPE), Thermoplastic Polyurethane (TPU), and combinations thereof. 6. The battery pack case assembly of claim 1, wherein the long fiber or continuous fiber of the case body and the long fiber or continuous fiber of the first separate reinforced member are selected from the group consisting of: glass fibers, carbon fibers, aramid fibers, volcanic ash fibers, natural fibers, and combinations thereof. 7. The battery pack case assembly of claim 1, wherein the first separate reinforced member has a bracket type shape with one or more reinforcing ribs, and wherein when the side bracket part of the case body and the reinforced member are coupled to each other a closed-section structural region for absorbing collision energy is formed. 8. The battery pack case assembly of claim 1, wherein the first separate reinforced member is has a planar shape, and is coupled to the opposing side bracket parts of the case body. 9. The battery pack case assembly of claim 1, wherein the second separate reinforced member is bonded to a surface of the bottom of the case body, or is disposed within the bottom of the case body. 10. The battery pack case assembly of claim 9, wherein the surface is an upper surface, a lower surface, or both upper and lower surfaces of the bottom. 11. The battery pack case assembly of claim 1, wherein the continuous fiber of the second separate reinforced member disposed at the bottom of the case body is arranged in one direction in the plastic matrix, or is fixed in a form of a woven fiber in which the continuous fibers cross each other in longitudinal and latitudinal directions. 12. The battery pack case assembly of claim 11, wherein the continuous fiber is longitudinally arranged in one direction in a right and left width direction that is orthogonal to a forward and backward longitudinal direction of the case body. 13. The battery pack case assembly of claim 9, wherein the plastic matrix of the both the first and second separate reinforced member disposed at the bottom of the case body is selected from the group consisting of: Polypropylene (PP), Polyamide (PA), Polyether Ether Ketone (PEEK), Polycarbonate (PC), Polyphenylene Sulfone (PPS), Polyphenylene Ether (PPE), Thermoplastic Polyurethane (TPU), and combinations thereof. 14. The battery pack case assembly of claim 1, wherein the continuous fiber of the second separate reinforced member disposed at the bottom of the case body is selected from the group consisting of: glass fibers, carbon fibers, aramid fibers, volcanic ash fibers, natural fibers, and combinations thereof.
