Arrangement for leakage detection in a cooling system

Abstract

An arrangement to detect leakage of a liquid coolant from a cooling circuit, such as of a cooling system of a battery pack in a vehicle is provided. A sensor assembly measures an electric parameter between an inlet and an outlet of the cooling circuit, the electric parameter being dependent on an amount of liquid coolant present between the inlet and outlet, wherein the sensor assembly comprises a pair of probes. An electronic control unit receives data comprising the measured electric parameter from the sensor assembly and to determine whether the measured electric parameter between the inlet and the outlet is indicative of a leakage of liquid coolant from the cooling circuit.
