Battery system
View Patent ↗A battery module includes a plurality of battery cells and a system configured for passing a fluid past at least a portion of the plurality of battery cells in a parallel manner.
1. A battery module comprising:
a plurality of battery cells located in a housing; and
a system configured for conveying a fluid past at least a portion of the cells in a parallel manner from a first end of each of the cells to a second end of each of the cells opposite the first end;
wherein each of the cells is located in an individual cell container of the housing, each cell container including a plurality of apertures positioned above the cell located therein and configured to direct the fluid through the associated cell container so that the fluid is evenly distributed about a perimeter of the cell, wherein the system is configured such that fluid flowing past each individual cell is directly exhausted from the battery module after passing the second end of each individual cell.
2. The battery module of claim 1 , wherein the fluid comprises air.
3. The battery module of claim 1 , wherein the system includes a manifold for distributing the fluid.
4. The battery module of claim 3 , wherein the fluid is forced from the manifold past the plurality of battery cells.
5. The battery module of claim 3 , wherein the fluid is pulled into the manifold after passing the plurality of battery cells.
6. The battery module of claim 3 , wherein the manifold includes at least one channel, wherein each channel includes at least one end for distributing the fluid toward at least one of the plurality of cells.
7. The battery module of claim 1 , wherein the apertures are distributed evenly about the perimeter of each of the cells.
8. The battery module of claim 1 , wherein the module includes twelve battery cells.
9. The battery module of claim 1 , wherein each of the plurality of battery cells includes a plurality of positive terminals and a plurality of negative terminals.
10. The battery module of claim 9 , wherein the terminals of each of the plurality of battery cells are configured for coupling to a terminal of another battery cell.
11. The battery module of claim 1 , wherein each of the cells has a generally oval cross-sectional shape.
12. The battery module of claim 1 , wherein each of the cells includes a vent for releasing gas from within the cells.
13. The battery module of claim 1 , wherein the plurality of battery cells are electrically coupled together with buss bars, the buss bars coupling a positive terminal of a first one of the cells to a negative terminal of a second one of the battery cells.
14. The battery module of claim 1 , wherein the cells are arranged so that a positive terminal of each of the cells is adjacent a negative terminal of an adjacent one of the cells.
15. The battery module of claim 1 , wherein the module is configured for use in a vehicle.
16. The battery module of claim 1 , wherein the module is configured to be operatively connected to a plurality of other battery modules to form a battery system.
17. The battery module of claim 16 , wherein the fluid system supplies fluid to both the module and other modules.
18. A battery module comprising:
a plurality of battery cells located in a housing; and
a system configured for conveying fluid past at least a portion of the cells in a parallel manner from a first end of each of the cells to a second end of each of the cells opposite the first end;
wherein a manifold is located in the housing to distribute fluid evenly from a common inlet to the cells and wherein each of the cells is located in an individual cell container of the housing, each cell container including a plurality of apertures configured to direct the fluid through the associated cell container so that the fluid is evenly distributed about a perimeter of the cell, wherein the system is configured such that fluid flowing past each individual cell is directly exhausted from the battery module after passing the second end of each individual cell.
19. A battery module comprising:
a plurality of battery cells; and
a system configured for passing a fluid past the plurality of battery cells in a parallel manner from a first end of each of the plurality of battery cells to a second end of each of the plurality of battery cells opposite the first end, wherein the system includes a manifold comprising a plurality of discrete channels, each channel extending from a common inlet of the system to a subset of the plurality of battery cells, wherein the system is configured such that fluid flowing past each individual cell is directly exhausted from the battery module after passing the second end of each individual cell.
20. The battery module of claim 19 , wherein the battery module comprises a housing for the plurality of battery cells.
21. The battery module of claim 20 , wherein each of the plurality of containers comprises a plurality of apertures through which the fluid may flow and in fluid communication with one of the channels for routing the fluid evenly distributed about a perimeter of the battery cell.
