Composite battery enclosure

A battery enclosure for a vehicle chassis comprising:

• a base member having an upper and lower surface, the base member having a plurality of raised surface features on the upper surface outlining individual cells, each cell configured to receive at least one battery;
• wherein the lower surfaces of the base member is configured as a continuous surface;
• a cover member having an upper and lower surface, the cover member having a plurality of depending surface features on the lower surface outlining individual cells, the surface features of the cover member aligned with the surface features of the base member, and
• the cover member having at least one channel formed in the upper surface thereof, aligned with and extending along a length of the depending surface feature disposed on the bottom surface;
• a lattice support structure, the lattice support structure including a plurality of support members extending axially and a plurality of support members extending transversely,
• wherein the lattice support structure is configured to be at least partially disposed within the channel of the cover member and mounted to the vehicle chassis;
• and
• wherein a bottom surface of the lattice support structure is disposed above a top surface of the base member;
• wherein at least one of the cover member and base member include a plurality of individual layers, each layer having a functionally graded laminate.
