Hi team,
My customer is trying to test OCD1. OCD1 delay time is set 2 (It means 13.3ms). If load keep 25A to discharge to monitor PACK voltage, the result is shown as below.
Channel #1 is PACK voltage and channel#2 is current. As you can see, the 2nd OCD1 delay time is higher than 1st. We are confused how to cause this symptom.
May I learn from you the reason?
Thanks for sending the settings. It looks like the second delay is 263 ms in the picture? I cannot find any reason for this delay value - it looks like it is ~ 250ms + 13.3 ms.
I think the issue might be that the DSG FET Protections A register is set to 0xA4 in the register settings. There may be additional delays if this value is not set to 0xE4 or 0x80.
Best regards,
Matt
