EV charging piles are core supporting equipment consisting of the pile body, charging module, billing system, and human-machine interface. Their power ranges from 7kW residential slow charging to 480kW ultra-fast charging, adaptable to different vehicle models. Modern charging piles integrate IoT technology, supporting remote monitoring, fault diagnosis, and OTA upgrades to enhance user experience. With technological iterations, charging efficiency and compatibility continue to optimize, gradually alleviating "range anxiety".
