TITLE OF THE INVENTION
Electric Vehicle having a frame with battery assemblies spaced in a manner to form a collapsible mass to absorb energy during a collision. CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims the priority of U.S. provisional application No.
61/565581, filed on Dec. 1, 2011, which is herein incorporated by reference. BACKGROUND OF THE INVENTION
This invention relates to the technical field of automobile design and engineering. More specifically, this invention relates to improved design of electric vehicles that result in impved safety.
FIELD OF THE INVENTION DESCRIPTION OF RELATED ART
The traditional battery assembly of an electric vehicle contains all the storage batteries in one container, thus forming a single mass. The current state of the art for traction storage devices for electric vehicles is the use of single large battery box that is attached to the unibody or to the frame area. It has been reported in crash testing data gathered by the inventor that the mass contained in a single battery box during a collision is responsible for considerable damage to the vehicle and places the occupants at risk for injury. When subjected to a collision, the single massive battery container does not absorb the kinetic energy of the collision, but rather transfers the momentum of that container as a single moment of energy into the passenger
compartment. There is a need for improved design of electric vehicles to improve safety during collisions.
BRIEF SUMMARY OF THE INVENTION
The present invention provides for attaching electric vehicle battery pack assemblies along the frame of an electric vehicle in a spaced manner to form a collapsible mass to absorb energy during a collision. The proposed invention divides the mass between more than one container, such that, when subjected to a forward or rearward collision, the compartments will act independently and be forced together. The force it takes to bend the frame, to which the massive containers are attached, is subtracted from the force of deforming the passenger compartment. The proposed invention is termed the caterpillar design, which facilitates multiple compressions of the frame, which translates the energy of the collision into a deformation of the vehicle's frame that prevent harm to the passenger compartment. The bending of the vehicle's frame is a significant improvement over the traditional art, wherein a single, massive battery container does not absorb the kinetic energy of a collision, but rather transfers the momentum of that container as a single moment of energy into the passenger compartment.
The disclosed invention was developed as a way to disburse the energy of momentum from the massive battery pack over several compartments that are individually attached to a frame member of the electric vehicle. Each attachment may be permanent through welding or other permanent fixation to the frame, or it may be removable through the use of bolt processes or other removable fixation methods, such as brackets. When the main traction battery pack for an electric vehicle is spaced along the frame in any distance other than adjoining one another, the energy during a collision is divided and disbursed between them. The force it takes to collapse the battery compartments together is sufficient to bend the frame member. The energy it takes to
bend the main rear vehicle frame member is subtracted from the energy it takes to crush the passenger compartment, resulting in less damage to the passenger compartment and less injury to the occupants of the passenger compartment. This spacing of the main traction battery boxes of an electric vehicle is unique and novel and significantly adds to the passenger safety of the vehicle during a collision.
This summary of the invention does not necessarily describe all features of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

Referring now to the invention in more detail, an embodiment of the present invention, an embodiment of the present encompasses An electric vehicle main traction battery box that is formed from sheet metal. The material may be any suitable metal, but is preferably steel, and may be any suitable gage. In an embodiment, 18 gage steel or 16 gage steel is preferred. The metal (steel in a preferred
embodiment) is cut in a suitable pattern by any method known to those of skill in the art, such as by laser cutting. In an embodiment, the steel is laser cut to a suitable pattern, a preferred embodiment which is shown Fig. 3. The metal is then formed into a box in any suitable process. In a preferred embodiment, the metal is broken or folded along the pattern lines until the sheet is in the form of a box. In such an embodiment, tabs and edges on the metal sheet may be folded to fit together into a box, and then seam welded for strength. During formation of the box, the tabs may be spot-welded into place to keep the alignment and squareness of the box intact before it is seam welded. In an embodiment, the box is formed from a laser cut pattern of a lid (1), two end caps (2), a main body (3) with the tabs folded to a right angle to form a welded overlap for extra strength. Each box has a steel lid (1) bolted across the top to retain the batteries in a stationary and motionless position.
In an embodiment shown in Fig. 1, a box compartment for batteries is attached to the frame (1) in a permanent manner, through welding for example, or through a removable manner through bolting, for example. The space between the boxes is strategic so that the rotational force created by the mass of the battery box moving during a frontal impact is shown in Fig. 2. The spacing may be designed for aesthetics or for function, depending upon the vehicle, but the design should prove to absorb the energy from a frontal impact by forcing the frame to bend, instead of the energy being absorbed by the passenger compartment.
In the present invention, when the vehicle undergoes a collision, the momentum of each box, rather than simply transferring that kinetic energy forward as a crushing force to the passenger compartment, is deflected in a rotational force, using each box with the frame (Fig. 2) as a lever to torque the frame along the same arc of travel. The torque of each battery box against the frame, although still part of the total potential energy of the collision, is subtracted from the energy absorbed by the passenger compartment, thus sparing the compartment from excessive damage. The compression time is vastly broadened to improve safety of the passenger compartment.
In an embodiment, the present invention is an electric vehicle traction energy storage device— such as a lithium battery or batteries— container that is designed to hold a portion, rather than the entirety,
of the batteries in a vehicle and is attached to the unibody or to the frame of the electric vehicle with a space between each box for the total of the boxes.
In another embodiment, the present invention is a method of connecting or mounting the electric vehicle traction energy storage device— such as a Lithium battery or batteries— container to a frame or unibody other than the passenger compartment in such a way that the mount will stay attached during a frontal vehicle collision. This results in the energy transfers from the momentum of the battery box to the frame or unibody, thus deflecting the energy away from the passenger compartment.
In another embodiment, the present invention is a structural electric vehicle traction energy storage device— such as a Lithium battery or batteries— container with air-cooling through ventilation.
In another embodiment, the present invention is a structural electric vehicle traction energy storage device— such as a Lithium battery or batteries— container with electrically energized heating blankets or pads for the purpose of heating the storage devices to a suitable temperature to accept a recharging event.
In another embodiment, the present invention is an electric vehicle traction energy storage device— such as a Lithium battery or batteries— container mount that include clips, bolts, clamps, or other methods that allow the box to be mounted as a completely assembled subassembly in a high-speed assembly operation as a subassembly with a minimum of interconnections.
In another embodiment, the present invention is an electric vehicle traction energy storage device, or a portion thereof— such as a Lithium battery or batteries— that is constructed as a modular unit for easy installation during manufacturing and easy removal with tools and suitable skills for easy maintenance.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and
methods within the scope and spirit of the invention. Moreover, the terms "consisting", "comprising" and other derivatives from the term "comprise" are intended to be open-ended terms that specify the presence of any stated features, elements, steps, or components, and are not intended to preclude the presence or addition of one or more other features, elements, integers, steps, components, or groups thereof. Moreover, Applicants have endeavored in the present specification and drawings to draw attention to certain features of the invention, it should be understood that the Applicant claims protection in respect to any patentable feature or combination of features referred to in the specification or drawings. The drawings are provided to illustrate features of the invention, but the claimed invention is expressly not limited to the illustrated embodiments.
