Data acquisition: The temperature sensor is installed in the key part of the charging pile to monitor the temperature in real time and transmit the data to the control system for real-time acquisition.

Data processing: The control system calculates the algorithm according to the collected temperature data, and decides whether to adjust the charging power, issue a temperature alarm or automatically stop charging and other measures.

Temperature management strategy: Based on the data of the temperature sensor, the charging pile implements temperature management strategies, such as dynamically adjusting the charging power, reducing the charging speed or stopping the charging when the temperature rises.

Feedback control: When the temperature exceeds the preset threshold, the system can automatically send an alarm through the control logic and cut off the power supply to avoid equipment damage and safety accidents.

Intelligent monitoring: The use of equipment such as NTC temperature sensors, because of its high accuracy, simple structure and good cost performance, become the ideal choice to achieve charging pile overtemperature protection. The resistance value of the NTC temperature sensor decreases with the increase of temperature, and the resistance change is monitored in real time by the external circuit, thus reflecting the current temperature state.

Through such a system, the DC charging pile can improve the charging efficiency and reliability under the premise of ensuring safety, and also provide important data support for the maintenance and fault diagnosis of the charging pile.
