1. A battery case for a vehicle, the battery case comprising:
a main body in which a loading region is partitioned for loading a plurality of battery modules;
a sidewall frame forming a sidewall edge portion of the main body and extending upwards, the sidewall frame including a curved portion to correspond with a shape of a vehicle body adopting a multi-link trailing-arm suspension structure of the vehicle; and
a plurality of first support members and a plurality of second support members that extend respectively along transverse and longitudinal directions of the main body for partitioning of the loading region,
wherein the loading region of the main body is partitioned into a plurality of sections so that the plurality of first support members is disposed to partition the inside of the main body into a predetermined number of regions in the longitudinal direction while the plurality of second support members is disposed to partition, again, the predetermined number of regions in the traverse direction,
wherein the predetermined number of regions includes a first region, a second region, a third region and a fourth region,
wherein the first region is partitioned, by the second support member including a pair of second support members disposed therein among the plurality of second support members, into a power relay assembly (PRA) region in a center portion thereof and a first loading region and a second loading region on opposite sides of the PRA region, and
wherein a rear area having the battery modules stacked in the first loading region and the second loading region is a region where a seat of the vehicle body is configured to be positioned in an upper part thereof, so that a case part covering the main body is formed flat, and a front area thereof is a region corresponding to a legroom, so that the case part is configured to form a shape with a predetermined slope and whose height is lowered toward a front thereof.
