Abstract

Methods and systems for assessing operation of a cooling system of an electric vehicle are described. In one example, a super heating temperature at an inlet of a compressor may be generated solely via a temperature sensor and a pressure sensor. The super heating temperature may be compared against a threshold super heating temperature to judge whether or not an amount of refrigerant in the cooling system is as expected.
