Abstract
A battery pack comprises one or more cells 30, a flexible duct 50 positioned proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 50 and at least one of the one or more cells 30 and a potting means which at least partially surrounds at least a part of the duct 50. A method of manufacturing a battery pack comprises providing one or more cells 30, positioning a flexible duct 50 proximally to the surface of at least one of the one or more cells 30 such that heat can be exchanged between the duct 0 and the at least one of the one or more cells 30, inserting fluid into the duct 50 and at least partially surrounding at least a part of the duct 50 with a potting means. The potting means may be expandable foam.
Claims25
A battery pack comprising:
- one or more cells;
- a flexible and inflatable duct positioned proximally to a surface of at least one of the one or more cells such that heat can be exchanged between the duct and at least one of the one or more cells;
- and a potting material adapted to act as a support for at least a part of the duct wherein, in use, the duct partially conforms to the surface of the one or more cells by a heat transfer fluid flowing through the duct to pressurize the duct into an expanded state where no pre-formed radiused depressions are formed into the duct for conforming the duct in the expanded state to the one or more cells and wherein no portion of the duct comes into contact with another portion of the same duct further along a length of the duct or with a different duct, wherein the duct is free from internal obstructions such that in use a flow of the heat transfer fluid is not divided into separate paths in a same direction.
A method of manufacturing a battery pack, the method comprising:
- providing one or more cells;
- positioning a flexible and inflatable duct proximally to a surface of at least one of the one or more cells such that heat can be exchanged between the duct and the at least one of the one or more cells;
- inserting fluid into the duct to pressurize the duct into an expanded state such that the duct partially conforms to the surface of the one or more cells where no pre-formed radiused depressions are formed into the duct and wherein no portion of the duct comes into contact with another portion of the same duct further along a length of the duct or with a different duct;
- and providing a potting material adapted to act as a support for at least a part of the duct, wherein the duct is free from internal obstructions such that in use a flow of the fluid is not divided into separate paths in a same direction.
