Our freely programmable CHARX control professional DC charging controller is the intelligence behind modern CCS and CHAdeMO charging stations for mode 4 fast charging in accordance with IEC 61851-23. The controller communicates with the vehicle, monitors the charging process, controls parameters such as the charging current, and optionally performs additional tasks, such as visualizing the process on an operator panel. Its 3G modem allows convenient remote maintenance. In addition to DC charging, the controller also supports an AC charging point.
