Abstract: An immersion cooling system for a battery of an electric vehicle. The immersion cooling system includes an incompatible fluid detection system configured to detect a presence of an incompatible fluid within a fluid circuit of the immersion cooling system. The incompatible fluid can include a non-dielectric fluid that has entered or accumulated within the fluid circuit, as well as a dielectric fluid that has been contaminated or is reaching, if not already attained, an end-of-life for the dielectric fluid. In response to a determination of a presence of the incompatible fluid in the fluid circuit, a notification can be generated to alert an operator of the detection of the incompatible fluid. Additionally, the system can take actions, including closing a valve(s), deactivating a pump, and/or opening a bypass circuit(s), among other actions, to isolate at least the battery from the incompatible fluid.
