The AC EV Charger controller has a residual current monitor function to monitor currents in the system which protects the system in the event of fault current being detected.
OVERVIEW OF THE CONTROLLER
E32T21 FEATURES The controller is a DIN rail mounted control module for IEC 61851 compatible EV charge points.Key features include RCMU and DLB, helping charge station manufacturers and installers meet regulations in a cost-effective way and protect against electric shock in the unlikely event of an earth fault problem.
SEQUENCE OF CHARGING PROCESS INITIALIZATION
After the operating voltage is applied, the module carries out initializations and function tests indicated and then waits for vehicle connection (indicated by pulsing blue LED). Tethered version:indicated by pulsing blue LED Socket outlets version:indicated by steady blue LED CHARGING PROCESS The charging module waits for a charging cable or vehicle to be connected (state A) indicated . If an approved connecting cable has been connected and state B is indicated by the vehicle. Tethered version:indicated by steady blue LED Socket outlets version:indicated by pulsing blue LED .
After interlocking, the charge-enable relays are activated if the vehicle is signalling state C. The charging process is activated, and the LED is changed to steady-green( Tethered version)or pulsing[1]green(Socket outlets version). If state D is indicated (ventilation required) then charging and interlock are deactivated as the E32T21 does not provide a fan-enable mechanism, and the LED is changed to steady-red .
The AC EV Charger Controller has stable performance and is suitable for EV charging station manufacturers. AEGEN not only produces ev charger accessories, but also DC EV charging station, AC EV Charger, EV Charging Accessories RCMU and energy storage EV charging station, which can be customized by OEM.
