Battery pack for vehicle

A battery pack for a vehicle, the battery pack comprising:

• a frontward wall;
• a rearward wall;
• lateral side walls connecting opposite ends of the frontward and rearward walls to define an accommodating space for accommodating battery modules;
• a longitudinal member having first and second ends supported on the frontward and rearward walls, respectively, while crossing the accommodating space, wherein only one longitudinal member is disposed in the accommodating space;
• a transverse member having first and second ends supported on the lateral side walls, respectively, while intersecting the longitudinal member across the accommodating space, wherein only one transverse member is disposed in the accommodating space;
• and
• a reinforcing bracket disposed at an intersection between the longitudinal member and the transverse member, the reinforcing bracket increasing a coupling rigidity between the longitudinal member and the transverse member so that the coupling rigidity with the reinforcing bracket is greater than the coupling rigidity of the same structure without any reinforcing bracket.

A method of manufacturing a battery pack for a vehicle, the method comprising:

• connecting opposite ends of a frontward wall and a rearward wall with lateral side walls to define an accommodating space for accommodating battery modules;
• attaching a longitudinal member across the accommodating space, wherein first and second ends of the longitudinal member are supported on the frontward and rearward walls, respectively;
• attaching a transverse member to intersect the longitudinal member across the accommodating space, wherein first and second ends of the transverse member are supported on the lateral side walls, respectively;
• and
• attaching a reinforcing bracket at an intersection between the longitudinal member and the transverse member thereby increasing a coupling rigidity between the longitudinal member and the transverse member.
