Abstract

The present invention provides a battery pack housing assembly for an electric vehicle, which is formed of a lightweight composite material to reduce the weight and configured to have a dual laminated structure with a closed cross-sectional area formed by composite molding to absorb impact energy. For this purpose, the present invention provides battery pack housing assembly for an electric vehicle using a plastic composite material, the battery pack housing assembly having an upper cover mounted at the bottom of a vehicle body, a lower housing, and a battery pack received and mounted in the lower housing, wherein the lower housing has a dual laminated structure with a closed cross-sectional area formed by bonding an upper plate and a lower plate, each composed of a fiber reinforced plastic composite material, to absorb impact energy, thus increasing structural stiffness.

Description

technical field [0001] The present invention relates to battery case assemblies for electric vehicles using plastic composite materials. More particularly, the present invention relates to a battery pack case assembly for an electric vehicle, which is formed of a lightweight composite material to reduce weight, and is configured to have a double layer with a closed cross-sectional area formed by composite molding structure to absorb impact energy. Background technique [0002] Generally, a battery pack case assembly used in an electric vehicle typically includes a battery pack, a battery management system, a blower, an upper cover, a lower case, a structural reinforcement member, etc., and is mounted to the bottom of the vehicle body (refer to figure 1 ). [0003] The upper shroud does not require large loads and therefore can be formed using typical plastic composite molding processes. The lower case and structural reinforcements are formed from steel using compression f...
