  • Publication number: 20250145040
    Abstract: A method for monitoring an electric vehicle charging apparatus is provided. A charging pile that includes a power meter and a processor is used to provide a charging current to an electric vehicle through a charging connector. The power meter detects the charging current to generate an initial current value and an initial power value that correspond to an initial charging time, and a present current value and a present power value that correspond to a present time, so that the processor calculates an initial resistance value and a present resistance value of the charging connector accordingly, and then calculates an estimated present temperature value of the charging connector based on the initial resistance value and the present resistance value. The estimated present temperature value is compared with an over-temperature threshold to determine whether to reduce the charging current.
