Abstract
A rechargeable energy storage system for a vehicle including a bottom shear plate and a side enclosure having a bottom end connected to the bottom shear plate. A top shear plate is connected to a top end of the side enclosure and a plurality of battery cells are suspended from a bottom of the top shear plate by corresponding mating features that secure the plurality of cells to the top shear plate.
Claims14
A rechargeable energy storage system for a vehicle, comprising:
- a bottom shear plate;
- a side enclosure having a bottom end connected to the bottom shear plate;
- a top shear plate connected to a top end of the side enclosure;
- and
- a plurality of battery cells are suspended directly from a bottom of the top shear plate by corresponding mating features that secure the plurality of cells to the top shear plate, the corresponding mating features including a plurality of first mating features formed directly on the shear plate for receiving a plurality of second mating features formed directly on the plurality of battery cells, wherein the plurality of first mating features include one of:
- i) a threaded protrusion on the plurality of battery cells,
- ii) a protruding portion on the plurality of battery cells, and
- iii) a flange on the plurality of battery cells;
- and the plurality of second mating features include a corresponding one of:
- i) a plurality of threaded apertures on the shear plate for receiving a respective one of the threaded protrusions on the plurality of battery cells,
- ii) a plurality of apertures on the shear plate wherein the plurality of apertures include an elastic retention feature wherein the apertures include an elastic retention feature for engaging a respective one of the protruding portions on the plurality of battery cells, and
- iii) a plurality of slots on the shear plate for receiving a respective one of the flanges of the plurality of battery cells.
