[0002] The charging pile is similar to a refueling machine in a gas station, can be fixed on the ground or a wall, is installed in a public building (a public building, a shopping mall, a public parking lot, etc.) and a residential parking lot or a charging station, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with an alternating current power grid, and the output end is provided with a charging plug for charging electric vehicles. The charging pile generally provides two charging modes of conventional charging and fast charging. People can use a specific charging card to swipe on a human-machine interactive operation interface provided by the charging pile, and perform operations such as a corresponding charging mode, a charging time, and fee data printing. The charging pile display screen can display data such as a charging amount, a fee, and a charging time.

[0003] Automation refers to a process in which a machine device, system or process (production, management process) achieves an expected goal through automatic detection, information processing, analysis and judgment, and control without or with less direct human intervention.

[0004] The inspection instrument is an industrial measurement and control instrument, which can be used in cooperation with various sensors and transmitters, can detect, alarm, control, output, collect data and communicate with multiple temperature, pressure, liquid level, flow, weight, current and voltage industrial process parameters, and the charging pile automatic inspection system belongs to one of the inspection instruments.

[0005] The authorized publication number "CN113643454A" records "a charging pile field safety comprehensive inspection system for detecting field safety problems of a load device connected with a direct current charging pile, which comprises a safety detection module, a BMS simulation device, an oscilloscope module and a host computer integrated in the same tool box. The safety detection module is used to detect the temperature rise condition, insulation condition, noise size and harmful gas in the direct current charging process of the direct current charging pile. The BMS simulation device has a built-in battery voltage simulation circuit and has a simulation function of the starting voltage of the direct current charging pile, and is used to detect whether the direct current charging pile has a safety judgment function when the load device voltage is abnormal. The device is safe and portable, can complete various safety detection of the charging pile field, and has a wide application space".

[0006] The charging pile field safety comprehensive inspection system in the above patent solves the simulation function of the starting voltage of the charging pile, solves the voltage U2 simulation simulation function, solves the voltage type and current type two test tests, solves the charging pile working state analysis and abnormal fault diagnosis, realizes calculation and prints the original report, and solves the electric vehicle conduction charging interoperability test. It has a wide application space. In the construction process of the charging station or charging pile supporting facilities of the electric vehicle, the inspection equipment needs to be used to participate in the operation of the charging pile, monitor various operating parameters in the operation of the charging pile, assist the operation of the charging pile, facilitate the management of the charging pile, but ignore the detection of the electric vehicle in the charging process. The temperature anomaly at the battery of the car in the charging process cannot be detected, which causes the car to self-ignite due to abnormal temperature soaring at the battery of the car, and cannot exclude the safety hidden danger of the charging pile caused by the car charging in advance.
