Embodiment Construction

[0033] Electric powered vehicles equipped with battery packs may use reinforcement materials for body crashes and reinforcement materials for battery packs to prepare for a crash event of the motor vehicle.

[0034] For battery housings, anti-collision properties may be important to protect the battery pack therein, and it may be important to increase rigidity against various vibrations caused by road surfaces during motor vehicle driving.

[0035] In this case, the cover member responsible for the upper portion of the outer surface of the battery case and the base member for the lower portion may be manufactured mainly by press molding. In order to strengthen the battery case, various reinforcement materials can be added inside and outside the battery case to meet its performance.

[0036] The reinforcing material should fulfill the functions of maintaining the shape of the battery pack and protecting the battery pack from explosion and absorbing external shocks.

Abstract

A battery case according to one embodiment may include: a base plate member; a support member surrounding the base plate member, having a closed cross-section, and supporting the base plate member; and an absorbing member coupled to an outer side of the support member so as to form a closed cross-section and absorb an external impact.

Description

technical field [0001] The present disclosure relates to battery housings and motor vehicles including battery housings. Background technique [0002] The battery pack of the electric motor vehicle may be constructed such that the modules, the assemblies of the secondary battery cells, are provided as a plurality of modules and the plurality of modules are installed therein. [0003] Motor vehicles equipped with battery packs can cause fires and explosions in the event of a collision involving a motor vehicle, posing a serious risk to the driver and passengers. SUMMARY OF THE INVENTION [0004] technical problem [0005] An aspect of the present disclosure is to provide a battery case capable of effectively absorbing external shocks and maintaining its shape, and a motor vehicle including the battery case. [0006] Another aspect of the present disclosure is to provide a battery case capable of stably fixing a battery pack and a motor vehicle including the battery case. ...
