Abstract
A propulsion system for an electric vehicle includes a battery pack having at least one battery cell. A cooling system includes a cooling plate abutting the battery cell. A heat sink is in thermal communication with the cooling plate by at least one carbon fiber brush coupled to at least one of the cooling plate and the heat sink.
Claims20
A propulsion system for an electric vehicle, comprising:
- a battery pack having at least one battery cell;
- a cooling system including a cooling plate abutting the battery cell, and
- a heat sink in thermal communication with the cooling plate by at least one carbon fiber brush coupled to at least one of the cooling plate and the heat sink.
A propulsion system for an electric vehicle, comprising:
- a battery pack having at least one battery cell;
- a cooling system including at least one cooling plate abutting the at least one battery cell;
- and
- a heat sink in thermal communication with the at least one cooling plate by at least one carbon fiber brush coupled to the at least one cooling plate and the heat sink, the carbon fiber brush including a bundle of carbon fibers, wherein the at least one carbon fiber brush includes a first carbon fiber brush coupled to a surface of the heat sink.

A cooling system for a battery cell, comprising:
- a cooling plate configured to abut the battery cell;
- and
- a heat sink in thermal communication with the cooling plate by at least one carbon fiber brush including a bundle of carbon fibers, the at least one carbon fiber brush coupled to one of the cooling plate and the heat sink and flexible at a free end to allow the free end of the at least one carbon fiber brush to maintain thermal communication between the cooling plate and the heat sink while allowing for differences in construction tolerance as a spacing difference between the cooling plate and the heat sink to be accommodated by flexure of the at least one carbon fiber brush at the free end.
