Abstract: A method of operating a heat transfer system includes circulating a heat transfer fluid through a heat transfer circuit in fluid communication with an electric system, and obtaining real-time measurements of fluid properties of the heat transfer fluid. A dimensional effectiveness factor for the heat transfer fluid (DEFfluid) is calculated based on the fluid properties and for a selected pump and a selected dominant flow regime within the heat transfer circuit, and a dimensional effectiveness factor for a reference fluid (DEFreference) is calculated for the selected pump and the selected dominant flow regime within the heat transfer circuit. A normalized effectiveness factor (NEFfluid) of the heat transfer fluid is then obtained, whereby a health of the heat transfer fluid is obtained. If the NEFfluid is below a predetermined threshold, the health will be considered deteriorated, and if the NEFfluid is above the predetermined threshold, the health will be considered viable.

Abstract: Heat transfer fluids corresponding to mixtures of at least one hydrogen bond donor and at least one hydrogen bond acceptor are provided. The heat transfer fluids can have an unexpectedly high heat capacity relative to the expected heat capacity based on the heat capacities of the at least one hydrogen bond donor and the at least one hydrogen bond acceptor. In some aspects, the heat transfer fluids can also have a sufficiently high electrical resistivity to be suitable for use in environments such as heat management systems in electric vehicles.
