Abstract: According to aspects of the present disclosure, a vehicle includes a braking system, at least one controller, and at least one memory. The braking system includes a brake fluid therein and a brake pedal. The at least one memory stores instructions that, when executed by the at least one controller, are configured to: determine, via a boiling-point module, a boiling point of a brake fluid within a braking system of a vehicle; determine, via a fluidic-properties module, fluidic properties of the brake fluid; determine, via a corrosion-inhibitor module, an amount of corrosion inhibitors within the brake fluid; determine, via a reserve-alkalinity module, a reserve alkalinity of the brake fluid; estimate, a brake-fluid life module, a remaining effective life of the brake fluid using the boiling point, the fluidic properties, the amount of corrosion inhibitors, and the reserve alkalinity; and adjust a response curve of the braking system.

Abstract: A cooling system for a rechargeable energy storage system (RESS) of a vehicle includes a coolant circuit configured to direct a coolant flow through the RESS to remove thermal energy from the RESS, and a refrigerant circuit through which a flow of refrigerant is circulated. A chiller is fluidly connected to the coolant circuit and the refrigerant circuit and is configured to transfer thermal energy between the coolant circuit and the refrigerant circuit. An auxiliary circuit is fluidly connected to the coolant circuit. The auxiliary circuit is configured to selectably direct at least a portion of the coolant flow across a first side of a cold plate for thermal energy exchange with a phase change material located at a second side of the cold plate. One or more valves are configured to selectably direct the at least a portion of the coolant flow through the auxiliary circuit.
