Abstract
A portable light weight battery pack (1) is formed of a pair of end plates (2), a plurality of cells (4) interposed between the end plates (2), and, a plurality of cell links (5). Each end plate (2) includes a first portion (6), and, a bus plate (11). The first portion (6) has a first surface (7) and a second surface (8), including, an arrangement of cutouts (9), and, an arrangement of fluid flow apertures (10). The bus plate (11) substantially overlays the first surface (7), and includes an arrangement of cell connection holes (12). An arrangement of fluid flow orifices (13) substantially align with said fluid flow apertures (10). The battery pack (1) may typically be used with electric vehicles and road-use assistance, for camping, mining and numerous industry applications.
Claims20
An end plate for a battery pack, the end plate including:
- a first portion, of substantially plate-like configuration having first and second surfaces, including:
- an arrangement of cell receiving cutouts formed therein in spaced apart relationship;
- and,
- an arrangement of fluid flow apertures provided intermediate said cell receiving cutouts;
- and,
- a bus plate, of substantially laminar configuration and formed of conductive material, substantially overlaying said first surface of said first portion, including:
- an arrangement of cell connection holes formed therein in spaced apart relationship and substantially in alignment with said cell receiving cutouts of said first portion;
- and,
- an arrangement of fluid flow orifices formed therein and which substantially align with said fluid flow apertures of said first portion.
The end plate as claimed in any one of the preceding claims, wherein the cell receiving cutouts are of substantial compatible shape to the shape of a cell adapted to be inserted therein, such as, but not limited to circular, square, rectangular or any other shape, in cross-section.
The end plate as claimed in any one of the preceding claims, wherein each fluid flow aperture and each fluid flow orifice is of substantially similar shape, together forming part of a fluid flow channel.
The end plate as claimed in any one of the preceding claims, wherein said first portion is at least partly formed of non-conductive material, which is preferably also able to resist temperatures over 60° C. and has low flammability, such as, but not limited to polycarbonate, polyaramid 6/6 glass-fibre reinforced, PTFE, PEEK, etc.
The end plate as claimed in any one of the preceding claims, wherein said bus plate is formed of any one or combination of a highly conductive material such as a metal such as, but not limited to copper, aluminium, nickel, etc., or a non-metallic conductor, such as, but not limited to graphene or a conductive polymer or a ceramic material.
A battery pack, including a pair of spaced apart end plates, a plurality of cells interposed therebetween, and, a plurality of cell links;
- each end plate including:
- a first portion, of substantially plate-like configuration having first and second surfaces, including:
- an arrangement of cell receiving cutouts formed therein in spaced apart relationship;
- and,
- an arrangement of fluid flow apertures provided intermediate said cell receiving cutouts;
- a bus plate, of substantially laminar configuration and formed of conductive material, substantially overlaying said first surface of said first portion, including:
- an arrangement of cell connection holes formed therein in spaced apart relationship and substantially in alignment with said cell receiving cutouts of said first portion;
- and,
- an arrangement of fluid flow orifices formed therein and which substantially align with said fluid flow apertures of said first portion;
- each cell including a first end and a second end, the first end being operatively engaged in a cell receiving cutout of a first of said end plates, and, a second end being operatively engaged in a cell receiving cutout of a second of said end plates;
- and,
- each cell link conductively connecting an electrode at a respective end portion of each said cell to the bus plate of its respective end plate.
A method for forming a battery pack including interposing a plurality of battery cells between a pair of end plates.
A method of forming a battery assembly including linking two or more battery packs using a link member.
