Abstract
Battery assemblies and methods of fabricating battery assemblies are provided. One such battery assembly comprises: an array of battery cells comprising plural rows, each row comprising plural cells, each cell extending between opposed first and second ends and having first and second terminals both at the first end; a carrier frame housing the array of cells and comprising an array of apertures corresponding to the array of cells, the first end of each cell is at least partially exposed by one of the apertures; and bus bars attached to the carrier frame between adjacent rows of the array such that each of the rows is adjacent two bus bars.
Claims20
A battery assembly comprising:
- an array of battery cells comprising plural rows, each row comprising plural cells, each cell extending between opposed first and second ends and having first and second terminals both at the first end;
- a carrier frame housing the array of cells and comprising an array of apertures corresponding to the array of cells, the first end of each cell at least partially exposed by one of the apertures;
- and
- bus bars attached to the carrier frame between adjacent rows of the array such that each of the rows is adjacent two bus bars,
- wherein:
- for each of the plurality of rows, the first terminal of each cell in the row is connected to one of the two adjacent bus bars and the second terminal of each cell in the row is connected to the other of the two adjacent bus bars;
- and
- portions of the bus bars and the apertures are complementarily shaped.
A method of fabricating a battery assembly, the method comprising:
- providing a carrier frame for housing an array of battery cells comprising plural rows, each row comprising plural cells, the carrier frame comprising an array of apertures corresponding to the array of cells;
- locating battery cells within the array, each battery cell extending between opposed first and second ends and having first and second terminals both located at the first end, the first end of each cell being at least partially exposed by one of the apertures in the carrier frame;
- attaching bus bars to the carrier frame between rows of the array such that each of the rows is adjacent two bus bars;
- and
- for each of the plurality of rows, connecting the first terminal of each cell in the row to one of the two adjacent bus bars and connecting the second terminal of each cell in the row to the other of the two adjacent bus bars,
- wherein portions of the bus bars and the apertures are complementarily shaped.
