  • Method and apparatus for determining electric vehicle charging inlet terminal temperature
    Patent number: 12752657
    Abstract: An electric vehicle charging system includes a temperature sensor for measuring the temperature of an inlet terminal of an electric vehicle charging inlet and an electronic controller configured to obtain an initial temperature value of the temperature sensor, obtain a current temperature value of the temperature sensor, calculate the inlet terminal temperature based on the initial temperature value, the current temperature value, a predetermined temperature sensor normalization factor, and a predetermined terminal normalization factor for the time after application of electrical power to the inlet terminal, and regulate the application of electrical power to the inlet terminal to maintain the inlet terminal temperature below a predetermined temperature threshold based on the calculated inlet terminal temperature. A method and a computer readable medium containing program instructions for determining an inlet terminal temperature of an electric vehicle charging inlet are also disclosed.
