Abstract

This paper designs and implements an intelligent charging pile monitoring system based on STM32 and ESP8266, aiming to enhance the safety, efficiency and user experience of the charging process for new energy vehicles. The system can collect key parameters such as voltage, current and temperature in real time, and is equipped with multiple protection mechanisms against over‑voltage, under‑voltage and over‑temperature. It also supports RFID user identity authentication to ensure operational safety. The system adopts Wi‑Fi direct connection mode without relying on cloud platforms, realizing low‑latency and high‑security data interaction between the charging pile and the local monitoring APP. The monitoring APP is developed based on the E4A platform, providing functions such as real‑time data curve display, remote start‑stop control and parameter configuration. Test results show that the system response time is less than 0.5 s, the data packet loss rate is lower than 0.3%, and the system runs stably and reliably. The scheme effectively ensures charging safety, significantly reduces deployment and operation costs, and has good application value and promotion prospects.
