Abstract
A system includes a battery pack having a fluid inlet, a fluid outlet, and battery cells. The system also includes a thermal system having heat transfer fluid, a flow device, an inlet thermocouple, one or more internal thermocouples connected to a respective one of the battery cells, and a controller. The controller receives and processes temperature signals from the thermocouples using a thermal model to diagnose performance of the flow device. The system may estimate values when an outlet thermocouple is not used. A method includes circulating the fluid through the battery pack, positioning an inlet thermocouple proximate to the fluid inlet, and connecting one or more internal thermocouples to respective battery cells. A controller receives and processes temperature signals from the inlet thermocouple and the internal thermocouple(s) to diagnose performance of the flow device using the thermal model.
