Battery pack mounting assembly
An electrified vehicle includes a vehicle frame, a battery pack mounted to the vehicle frame, a primary bracket secured to each of the vehicle frame and the battery pack, and a support bracket secured to the battery pack and the primary bracket. The support bracket increases the stiffness of the primary bracket.
1. An electrified vehicle, comprising:
a vehicle frame;
a battery pack mounted to the vehicle frame;
a primary bracket secured to each of the vehicle frame and the battery pack;
a support bracket secured to the battery pack and the primary bracket;
wherein the support bracket includes a first mounting tab mounted to the battery pack, a second mounting tab mounted to the primary bracket, and a wall that extends between the first mounting tab and the second mounting tab;
wherein the first mounting tab includes a distal end portion that is spaced from the wall and includes a contoured profile; and
a weld bead that follows the contoured profile to connect the first mounting tab to the battery pack.
2. The electrified vehicle as recited in claim 1 , wherein the weld bead includes at least one curved portion.
3. A method, comprising:
securing a battery pack to a vehicle frame with a mounting assembly that includes a primary bracket and a support bracket, wherein the support bracket extends between the battery pack and the primary bracket to increase the stiffness of the primary bracket,
wherein securing the battery pack includes:
welding the primary bracket to an enclosure of the battery pack; and
mechanically fastening the primary bracket to the vehicle frame.
4. The method as recited in claim 3 , wherein the support bracket includes a predefined failure area.
5. A method comprising:
securing a battery pack to a vehicle frame with a mounting assembly that includes a primary bracket and a support bracket, wherein the support bracket extends between the battery pack and the primary bracket to increase the stiffness of the primary bracket,
wherein securing the battery pack includes:
welding the support bracket to an enclosure of the battery pack with a first weld bead; and
welding the support bracket to the primary bracket with a second weld bead.
6. The method as recited in claim 5 , wherein the first weld bead extends along a non-linear path and the second weld bead extends along a linear path.
7. An electrified vehicle, comprising:
a vehicle frame;
a battery pack mounted to the vehicle frame;
a primary bracket secured to each of the vehicle frame and the battery pack;
a support bracket secured to each of the battery pack and the primary bracket;
a first weld bead securing the support bracket to the battery pack; and
a second weld bead securing the support bracket to the primary bracket.
