In addition, the stations are equipped with facilities such as convenience stores, restrooms, and free WIFI, and combined with marketing activities, user repurchase rates are effectively improved; By implementing tiered access control, encrypted data transmission, and audited operation logs, the system ensures access and data privacy. At the device level, voltage, current, and temperature parameters are monitored in real time. In case of abnormalities, charging is automatically cut off and alarms are triggered. Combined with fault database matching and troubleshooting solutions, the device fault resolution rate is effectively improved, and availability is effectively maintained.
