Abstract
Provided herein are apparatus, systems, and methods for reducing noise in an electric vehicle. The apparatus can include a cabin floor, a battery pack, and a stiffener positioned between the cabin floor and the battery pack. The cabin floor can include a recess that that defines a volume in the cabin floor. The battery pack is coupled to the cabin floor, and includes a plurality of battery cells generating a voltage and a current. The stiffener includes a first stiffener surface that faces the cabin floor, a second stiffener surface that faces the battery pack, and a first stiffener element that extends out of the first stiffener surface and conforms to a shape of the recess. The first stiffener element is positioned on the first stiffener surface to align with a position of the recess in the cabin floor.
Claims20
An electric vehicle apparatus, comprising:
- a cabin positioned between a front portion and a rear portion of an electric vehicle, comprising:
- cabin frame side rails, and
- a cabin floor that extends between the cabin frame side rails, the cabin floor including a first cabin floor surface and a second cabin floor surface, the first cabin floor surface positioned on an underside of the electric vehicle, the first cabin floor surface including:
- a recess that defines a volume in the cabin floor;
- a battery pack coupled to the cabin floor, the battery pack including:
- a plurality of battery cells to generate a voltage and a current, the battery pack to provide the voltage and the current to the electric vehicle, and
- a first battery pack surface that faces the first cabin floor surface;
- and
- a stiffener disposed between the battery pack and the cabin floor to impart stiffness to the cabin floor, including:
- a first stiffener surface that faces the first cabin floor surface,
- a second stiffener surface that faces the first battery pack surface, and
- a first stiffener element that extends out of the first stiffener surface and conforms to a shape of the recess, the first stiffener element positioned on the first stiffener surface to align with a position of the recess in the first cabin floor surface.
A method to stiffen a cabin floor of an electric vehicle, comprising:
- providing a cabin positioned between a front portion and a rear portion of an electric vehicle including cabin frame side rails, and a cabin floor that extends between the cabin frame side rails, the cabin floor including a first cabin floor surface and a second cabin floor surface, the first cabin floor surface positioned on an underside of the electric vehicle, the first cabin floor surface including a recess that defines a volume in the cabin floor;
- covering at least a portion of a first cabin floor surface with a stiffener, the stiffener having a first stiffener surface that faces the first cabin floor surface, a second stiffener surface opposite the first stiffener surface, and a first stiffener element that extends out of the first stiffener surface and conforms to a shape of the recess, the first stiffener element positioned on the first stiffener surface to align with a position of the recess in the first cabin floor surface;
- and
- covering the second stiffener surface with a battery pack including a plurality of battery cells generating a voltage and a current, the battery pack providing the voltage and the current to the electric vehicle, the battery pack having a first battery pack surface that faces the cabin floor surface, and
- coupling the battery pack to the cabin floor.
An electric vehicle, comprising:
- a chassis, comprising:
- a cabin positioned between a front portion and a rear portion of an electric vehicle, comprising:
- cabin frame side rails;
- a cabin floor that extends between the cabin frame side rails, the cabin floor including a first cabin floor surface and a second cabin floor surface, the first cabin floor surface positioned on an underside of the electric vehicle, the first cabin floor surface including:
- a recess defining a volume in the cabin floor;
- a battery pack coupled to the cabin floor, the battery pack including:
- a plurality of battery cells generating a voltage and a current, the battery pack providing the voltage and the current to the electric vehicle, and
- a first battery pack surface that faces the first cabin floor surface;
- and
- a stiffener disposed between the battery pack and the cabin floor for imparting stiffness to the cabin floor, including:
- a first stiffener surface that faces the first cabin floor surface,
- a second stiffener surface that faces the first battery pack surface, and
- a first stiffener element that extends out of the first stiffener surface and conforms to a shape of the recess, the first stiffener element positioned on the first stiffener surface to align with a position of the recess in the first cabin floor surface.
