Abstract

A battery pack includes a battery module, a lower case to which the battery module is fixed, an upper frame disposed on the vehicle upper side with respect to the lower case, and a support member disposed on both sides, in the vehicle width direction, with respect to the battery module. The support member is fixed to the lower case and the upper case in the state of extending in the up-down direction between the lower case and the upper frame, the support member supporting the upper frame from the lower side. A first deformation starting point portion is provided on the side of a portion of the support member that is fixed to the lower case, the first deformation starting point portion serving as a deformation starting point at which deformation starts when the support member falls toward one side in the vehicle width direction.

Dependent claims

A battery pack comprising:

a battery module configured to include a plurality of battery cells;
a lower floor member to which the battery module is fixed;
an upper floor member disposed on a vehicle upper side with respect to the lower floor member;
a support member disposed on both sides, in a vehicle width direction, with respect to the battery module and fixed to the lower floor member and the upper floor member in a state of extending, in a vehicle up-down direction, between the lower floor member and the upper floor member, the support member supporting the upper floor member from a lower side;
and
a first deformation starting point portion provided on a side of a portion of the support member that is fixed to the lower floor member, the first deformation starting point portion serving as a deformation starting point at which deformation starts when the support member falls toward one side in the vehicle width direction.
