Abstract
Official abstract text for this publication.
Systems and methods are provided securing a battery pack to a vehicle. Embodiments can comprise an internal cross member secured to a first side of the vehicle's chassis. A cooling plate can be placed on one side of the internal cross member opposite to the first side of the vehicle's chassis where the internal cross member is secured. A hat-shaped section can extend at least partially across a width of the vehicle and secured to a second side of the vehicle's chassis. A structural reinforcement member can partially surround a battery pack of the vehicle.
First claim
Opening claim text (preview).
What is claimed is: 1 . A system for securing a battery pack to a vehicle comprising: an internal cross member secured to a first side of the vehicle's chassis; a cooling plate placed on one side of the internal cross member opposite to the first side of the vehicle's chassis where the internal cross member is secured; a hat-shaped section extending at least partially across a width of the vehicle and secured to a second side of the vehicle's chassis, wherein the first side is opposite the second side, and wherein the hat-shaped section comprises a hollow, elongated member open at a first end, and closed at a second end opposite from the first end; and a structural reinforcement member at least partially surrounding a battery pack of the vehicle, wherein the structural reinforcement member and the battery pack are positioned within the hat-shaped section. 2 . The system of claim 1 , wherein the hat-shaped section comprises an aluminum structure, and wherein the structural reinforcement member comprises a steel structure. 3 . The system of claim 1 , further comprising a protection plate, wherein the structural reinforcement member is secured to the protection plate. 4 . The system of claim 3 , wherein the structural reinforcement member is nested between the protection plate and the vehicle's chassis. 5 . The system of claim 3 , wherein the hat-shaped section is fixed to the protection plate. 6 . The system of claim 3 , further comprising a side frame extending from a bottom of the vehicle to a top of the vehicle, wherein the structural reinforcement member is positioned between the protection plate and the side frame. 7 . The system of claim 1 , wherein the cooling plate is positioned between the internal cross member and the hat-shaped section. 8 . The system of claim 1 , wherein the internal cross member comprises a base portion, wherein the base portion's length matches a length of the hat-shaped section. 9 . The system of claim 1 , wherein the hat-shaped section and the structural reinforcement member are secured using a rivet nut. 10 . The system of claim 1 , wherein the hat-shaped section tightly surrounds the structural reinforcement member on three sides.
