Abstract
A battery assembly and a method of assembling a battery assembly are provided. The battery assembly comprises: an array of battery cells, the array comprising plural rows, each row comprising plural cells; a flexible printed circuit board (PCB) provided between two adjacent rows, of the plurality of rows of cells; and at least one temperature sensor provided adjacent to and electrically connected to the flexible PCB, each temperature sensor being operable to sense a temperature of one or more cells of the two adjacent rows.
Claims20
A battery assembly comprising:
- an array of battery cells, the array comprising plural rows each row comprising plural cells, the plural rows including at least a first row, a second row adjacent to the first row, and a third row adjacent to the second row;
- a plurality of flexible printed circuit boards (PCBs), each flexible PCB provided between two adjacent rows of the plurality of rows of cells, the plurality of flexible PCBs including a first flexible PCB provided between the adjacent first and second rows and a second flexible PCB provided between the adjacent second and third rows;
- and
- a plurality of temperature sensors, each temperature sensor provided adjacent to and electrically connected to one of the plurality of flexible PCB, each respective temperature sensor being operable to sense a temperature of one or more cells of the respective two adjacent rows.
The battery assembly of cl m wherein the battery cells are cylindrical cells.
A method of assembling a battery assembly, comprising:
- providing a cell carrier comprising an array of apertures for receiving battery cells, the array comprising plural rows, each row comprising plural apertures, the plural rows including at least a first row, a second row adjacent to the first row, and a third row adjacent to the second row:
- positioning a plurality of cells within the apertures of the first row of the array, the cells having side walls extending generally perpendicular to the array of apertures;
- providing a first flexible printed circuit board, PCB, over the side walls of the first row of cells;
- electrically connecting the first flexible PCB to at least one temperature sensor;
- positioning a plurality of cells within the apertures of the second row the array, the second row being adjacent to the first row of cells such that the flexible PCB is provided between the adjacent first and second rows of cells;
- providing a second flexible printed circuit board, PCB, over the side walls of the second row of cells;
- electrically connecting the second flexible PCB to at least one temperature sensor:
- and
- positioning a plurality of cells within the apertures of the third row the array, the third row being adjacent to the second row of cells such that the flexible PCB is provided between the adjacent second and second third of cells,
- wherein each of the temperature sensors is adjacent to one of the flexible PCBs and operable to sense a temperature of one or more cells of the two adjacent rows.
