What to do in case of a DC residual current detection?
 
This article helps to check in case DC is detected by the charger.
For specific regions guidelines prescribe that power on the charger side should be directly disconnected if a DC residual current is detected instead of giving the vehicle the time to trigger the disconnection. 

This is available as a setting which can be adjusted locally, using the ACE Service Installer or the MyEve app, and also remotely using a back office configuration key for this setting. 

Alfen provides two options for this setting:

  1. Smart: triggers the vehicle to initiate the disconnection of the power supply or the charger will disconnect after 5 seconds. 
     
  2. Immediate: immediately disconnects the power supply when a residual current is detected. 

Below you find step-by-step instruction on how to configure this parameter.

 
Onsite using the ACE Service Installer
  1. Connect the device with the ACE Service Installer directly to the charging station or to the local network that the charging station is connected to.
     
  2. In the ACE Service Installer, open the Alerts tab, indicated with the warning sign symbol.
     
  3. In the submenu, click on “RCD”.
     
  4. In the dropdown menu next to “6mA Detect Response”, select the desired setting.
     
  5. Press “Save”; the charging station will now update the setting and will disconnect power accordingly if a residual current of 6mA or higher is detected.

 
Onsite using the MyEve app
  1. Confirm that the device with the MyEve app is connected to the same local network as the charger.
     
  2. Open the MyEve app, go to the Advanced tab and navigate to Alerts.

     
  3. Tap on RCD, you can then select the desired option.


     

Remote using a back office

This setting can also be changed remotely in the back office by setting the configuration key 6mADetectResponse to either Smart or Immediate. Please refer to your back office supplier for instructions.
