Abstract
A rechargeable battery system, a battery pack, and methods of manufacturing the same are disclosed herein. The rechargeable battery system and/or battery pack can be for an electric vehicle. The rechargeable battery system and/or battery pack can include a plurality of battery cells arranged into one or more rows, a busbar, and a housing. The housing can include a plurality of receptacles that can engage with the plurality of battery cells to secure a relative position of the plurality of battery cells with respect to each other. The housing can define a cooling duct in thermal connection with the plurality of receptacles.
Claims20
A battery pack for an electric vehicle, the battery pack comprising:
- a plurality of battery cells arranged into one or more rows, wherein:
- each of the plurality of battery cells comprises a first terminal and a second terminal;
- and
- each of the plurality of battery cells comprises a first end and a second end;
- a busbar extending over the first ends of the plurality of battery cells, the busbar configured to conduct electrical energy to and from the battery cells, wherein the busbar connects to the first terminals and the second terminals of the plurality of battery cells, wherein the busbar defines a busbar cooling duct having an entrance and an exit, wherein the busbar cooling duct is in thermal connection with a plurality of contacts of the busbar;
- and
- a housing comprising a plurality of receptacles configured to engage with the plurality of battery cells to secure a relative position of the plurality of battery cells with respect to each other, wherein the housing defines a housing cooling duct in thermal connection with the plurality of receptacles.
A method of manufacturing a battery pack for an electric vehicle, the method comprising:
- arranging a plurality of battery cells into one or more rows, wherein:
- each of the plurality of battery cells comprises a first terminal and a second terminal;
- and
- each of the plurality of battery cells comprises a first end and a second end;
- positioning a busbar configured to conduct electrical energy to and from plurality battery cells over the first ends of the plurality of battery cells, wherein the busbar defines a busbar cooling duct thermally connected with a plurality of contacts of the busbar;
- and
- receiving the plurality of battery cells within a plurality of receptacles of a housing, wherein the receptacles are configured to engage with the plurality of battery cells to secure a relative position of the plurality of battery cells with respect to each other, wherein the housing defines a housing cooling duct in thermal connection with the plurality of receptacles.
