Battery cassette

1. A battery cassette, comprising:

a frame including one or more hollow tubes; and

a seal component having one or more hollow tubes aligned with the hollow tubes of the frame, wherein the frame and the seal component are configured to receive one or more battery cells in the aligned hollow tubes of the frame and the seal component;

wherein a material of the frame is different than a material of the seal component, and wherein the frame includes a rigid material and the seal component includes a compliant material.

2. The battery cassette of claim 1 , wherein the seal component is configured to secure the battery cells in the battery cassette.

3. The battery cassette of claim 2 , wherein each hollow tube of the seal component include an internal circumferential protrusion that is configured to engage with a mating recess in a battery cell.

4. The battery cassette of claim 1 , wherein each hollow tube of the frame circumferentially surrounds a respective battery cell.

5. The battery cassette of claim 1 , wherein each hollow tube of the frame is configured such that a circumferential air-gap is formed between an inner wall of the tube and an outer wall of a battery cell when the battery cell is received in the hollow tube.

6. The battery cassette of claim 1 , wherein the rigid material is a thermoplastic.

7. The battery cassette of claim 1 , wherein the frame and the seal component are formed by a molding process, and wherein the frame and the seal component are formed by overmolding.

8. The battery cassette of claim 1 , further comprising one or more mating features for mating two or more battery cassettes together.

9. The battery cassette of claim 8 , wherein the one or more mating features include one or more tongues and one or more grooves.

10. The battery cassette of claim 9 , wherein the tongues and grooves include snap-fit features.

11. The battery cassette of claim 1 , further including one or more protrusions located on a side and/or an end of the battery cassette.

12. The battery cassette of claim 1 , further including one or more snap-fit features located on a side and/or an end of the battery cassette.

13. A battery cassette, comprising:

a frame including one or more hollow tubes; and

a seal component having one or more hollow tubes aligned with the hollow tubes of the frame, wherein the frame and the seal component are configured to receive one or more battery cells in the aligned hollow tubes of the frame and the seal component;

wherein the frame includes a flame-retardant material and/or glass fibers, and wherein the seal component includes a thermoplastic elastomer.

14. A battery cassette, comprising:

a frame including one or more hollow tubes; and

a seal component having one or more hollow tubes aligned with the hollow tubes of the frame, wherein the frame and the seal component are configured to receive one or more battery cells in the aligned hollow tubes of the frame and the seal component;

one or more mating features for mating two or more battery cassettes together,

wherein the one or more mating features include one or more tongues and one or more grooves,

wherein the tongues and grooves extend substantially an entire height of the battery cassette.

15. A battery cassette, comprising:

a frame including one or more hollow tubes;

a seal component having one or more hollow tubes aligned with the hollow tubes of the frame, the hollow tubes of the frame and the seal component configured to receive one or more battery cells,

wherein the battery cassette circumferentially surrounds each battery cell along substantially an entire length of each battery cell

wherein the frame includes a rigid material and the seal component includes a compliant material.

16. The battery cassette of claim 15 , wherein the frame and the seal component each include at least two rows of hollow tubes, and wherein the rows of hollow tubes are offset from each other.

17. A battery cassette, comprising:

a frame configured to support a plurality of similarly oriented cylindrical battery cells therein, wherein an external surface of the frame includes,

(a) one or more first mating features configured to engage with corresponding mating features on a frame of a second battery cassette to removably couple the battery cassette to the second battery cassette, and

(b) one or more second mating features configured to engage with corresponding mating features on an electrically conductive plate that is configured to electrically couple the battery cassette to the second battery cassette;

wherein the one or more first and/or second mating features include one or more tongues and one or more grooves;

wherein the tongues and grooves extend substantially an entire height of the battery cassette.

18. The battery cassette of claim 17 , wherein the one or more first mating features of the battery cassette include the one or more tongues configured to engage with a correspondingly shaped one or more grooves of the second battery cassette.

19. The battery cassette of claim 17 , wherein the frame includes a plurality of hollow tubes that extend from a top surface of the frame to a bottom surface of the frame, wherein each hollow tube of the plurality of hollow tubes is configured to receive a battery cell therein.
