Abstract
A modular thermal management system for a battery in an electric vehicle is provided. The thermal management system includes a battery module having a plurality of module ports for conducting heat exchange fluid to regulate temperature in a traction battery. The thermal management system also includes a manifold having a plurality of connector ports corresponding to the plurality of module. A retention feature is located on the manifold or the battery module for securing the manifold to the battery module to ensure the connector ports remain fluidly sealed to the module ports
Claims20
A traction battery thermal management system comprising:
- a battery module having a plurality of battery cells and a heat exchanger for regulating temperature of the plurality of battery cells;
- a battery housing containing the battery module;
- a plurality of heat exchanger ports in fluid communication with the heat exchanger for conducting a heat exchange fluid to the heat exchanger;
- a manifold having a plurality of connector ports corresponding to the plurality of heat exchanger ports for distributing the fluid to the heat exchanger ports;
- a retention clip connected to one of the battery housing or the manifold;
- and
- a receiving portion formed in the other of the battery housing or the manifold to mate with the retention clip,
- wherein when the connector ports are fully secured to the heat exchanger ports, the retention clip mates with the receiving portion and prevents movement of the manifold to ensure the connector ports remain fluidly sealed to the heat exchanger ports.
A traction battery thermal management system comprising:
- a plurality of heat exchanger ports for conducting heat exchange fluid to a heat exchanger for regulating temperature of a plurality of battery cells;
- a manifold having a plurality of connector ports for distributing the fluid to each of the corresponding plurality of heat exchanger ports;
- an overmold portion formed along each of the plurality of heat exchanger ports;
- and
- a weld joint for bonding and sealing the overmold portion to the connector ports of the manifold, thereby ensuring the connector ports remain fluidly sealed to the heat exchanger ports.
