The alarm 000D008 happens during the communication procedure between the car (EV) and the charger (during a CHAdeMO charging session).

The reason for the problem is that there is a voltage deviation caused by a chip on the relay control board PN (Part Number): 3798100032S.

The voltage deviation is the difference between what the car is reading and what the charger is providing.

For example, the CHAdeMO-CSU data reads 380.5V while the charger is providing: 388.5V to the car.

The result would be that there is a voltage deviation of 8.5V which causes an alarm.

 
 

Solution

Replace Relay control board 
 
Tools required:
- Laptop with Admin access
-  RJ45 cable
- Voltmeter with alligator clips
- EV car (CCS)
Procedure:
1. Enable or install remote support sofware on your laptop (for remote access if necessary).
2. Make sure your laptop has administration access to enable you to change the IPV4.
3. Install the software “DeltaDC25Service Tool” from the following link: https://reurl.cc/Kp18dM Password - BV3d26g7laAd

4. After installing the software, connect the RJ45 cable from your laptop to the Chademo-CSU board of the charger as shown:
 
Figure 2. RJ45 port  connection
 
5. Set up the IPV4 of your laptop to the correct port at the following IP address:
 
Figure 3. IP address
 
6. Login to the "DeltaDC25Service Tool" and make sure the IP address is correctly entered as shown (below):
 
Figure 4. DeltaDC25Service Tool
 
7. When the IP address is correctly entered, login to the debug access and enter the password of the debug screen like in the UFC (e&c …. )
Do not forget, this password should not be shared with the customer:

8. When logged in press Connect and the charger will load the data from the charger:
 
Figure 6. Connect charger data
 
9. Go to Running status

10. Connect your voltmeter to the charger at points “d” and “b” as shown (below), do not forget the voltmeter needs to be in DC mode:
 
Figure 8. Voltmeter connection
 
11. Start a charging session with the car and look to see if there is a difference between the voltmeter reading and the software shown (below):
 
Figure 9. Voltmeter comparison
12. If there is more than a 3V difference, the relay control board needs to be replaced. If there is less than a 3V difference, the relay control board is not the cause of the issue.
