The 6 mA DC residual current detection, according to IEC 62955, integrated in the CC613 charge controller detects insulation faults in the vehicle. The charging process is stopped immediately when a DC fault current greater than 6mA flows. This not only prevents life-threatening personal injury, but the user immediately knows that they should have their electric vehicle checked, as this is an initial sign of a fault in the vehicle.
The DC residual current detection offers the end user the great advantage of not having to use an RCD type B. The use of a much cheaper RCD type A is sufficient.
The integrated charging plug emergency opener offers the advantage that in the event of a power failure, the home user can safely disconnect the charging cable from the charging station/wallbox.
The weld check integrated in the CC613 outputs an error message in case of a "sticking" contactor or load switch. Since in this case the power supply is not interrupted and thus a life-threatening current can flow, the weld check provides increased personal protection.
To further increase the safety against electric shock, the CC613 ensures a proper connection of the protective conductor (PE) to the controller with continuous PE monitoring. This means that the measurement methods, communication and monitoring always work properly.
