System logs

[Plow4]

The head unit has a micro sd card populated with system logs. 


Log file names: yyyy-mm-dd.txt

One file per day and periodic removal of older files.

Lines are comma separated JSON like key value pairs in curlies.

Lines are added at about one row per second. Only a small number of key value pairs are added per line at a time. Every line includes a “timestamp”.

UTC for the filename and timestamps comes from the GPS. Logging is a good reason not to remove the GPS.

See picture for some of the keys from some logs. 

Sample line:

{"epsu_encoder_temperature": 59.0, "epsu_current": 4083.97, "controller_1_fault_code": 4, "gearbox_temp": 57, "controller_2_motor_temperature": 56, "steering_angle": 8388, "timestamp": "2025-02-22T00:16:34.81Z", "bms_low_cell_voltage": 38854, "bms_high_cell_voltage": 38952, "bms_pack_current": 17, "controller_1_fault_level": 4}

Example usage: Check the log files for AC-X1 throttle errors:
grep controller_1_fault_code\":\ 47 *.txt

Well that’s interesting. The problem with the GPS is that it interferes with the amp. Also, from what I understand, the GPS is no longer in use as Arcimoto had the subscription turned off.

No. GPS is free for everyone. You are referring to the LTE (cellular).

Where did you get 47? I see 4, 57, 56, 8388, 38854, 38952, and 4.
