Is the DC fast charging station a specific implementation of leakage protection?

Specific implementation of leakage protection：

•  Hardware level：Residual current device: Install a residual current device inside the charging station. When the leakage current detected exceeds the set threshold, the power supply is automatically cut off.

• Current transformer: Install a current transformer inside the charging cable or charger to monitor current changes in real time. Once abnormal current is detected, the protection action is triggered.

• Ground fault protection: Integrate a GFCI inside the charging station to detect ground faults and cut off the power supply.

Software level：

• Fault detection algorithm: Monitor the change of current through software algorithms. When abnormal current is detected, the system will issue an alarm and cut off the power supply.

• Real-time monitoring: Monitor parameters such as current and voltage during the charging process in real time. Once an abnormality is found, protection measures are taken.
