Daly BMS - Repeated bms interruptions #770

Closed harald0815 closed 11 months ago

harald0815 commented 1 year ago

Describe the problem

Describe the problem

A connection problem occurs several times a day (NO BMS). after a restart everything works again. After some troubleshooting it seems the bms is going from ttyUSB0 to ttyUSB1. In addition, the problem occurs more often with Venus OS v3.00 than with v2.94. Before updating to v3.00 there were no problems.

Driver version

1.0.20230724beta

Venus OS device type

Cerbo GX

Venus OS version

v3.00 and v2.94

BMS type

Daly Smart BMS

Cell count

16

Connection type

Serial USB adapter to TTL

Config file

[DEFAULT]

; If you want to add custom values/settings, then check the values/settings you want to change in "config.default.ini"
; and insert them below to persist future driver updates.

; Example (remove the semicolon ";" to uncomment and activate the value/setting):

MAX_BATTERY_CHARGE_CURRENT = 120.0
MAX_BATTERY_DISCHARGE_CURRENT = 140.0
BATTERY_CAPACITY = 280
INVERT_CURRENT_MEASUREMENT = -1
BLOCK_ON_DISCONNECT = False

mr-manuel commented 1 year ago

If the adapter is changing often from ttyUSB0 to ttyUSB1 then probably a connection is loose or your hub is not working properly. Check in the discussions for a good USB hub. The driver cannot change anything in this case.

Please post the logs again in the proper format. See Driver log files.

harald0815 commented 1 year ago

the error also occurs when I connect the USB-UART adapter directly to the cerbo

This indicates that there is an issue between the Venus OS and the serial adapter. In this case the driver has no issue.

Have you tried another adapter?

Please post the logs again in the proper format. See Driver log files.

We always need the logs with the timestamps to see the timings, else it's difficult to help you.

pos-ei-don commented 1 year ago

I belive that some adapters need a massive amount of power from usb. I had several, which did not work with bad USB-Hubs (and I had a lot of bad hubs!!) or when several adapters got connected! So be careful!

towatai commented 1 year ago

Does your BMS offer the possibility to use an RS485 adapter instead of the UART adapter? I had similar problems, sometimes it ran for days, then suddenly several times a day the errors, really completely sporadic.

i completely disassembled and reassembled my entire system several times, tried different active USB hubs, nothing to do.

Then rather out of perplexity I just reconnected my two dalys for a long time via RS485->USB adapter, since then it's been running. I noticed that the system takes some time longer to connect to the BMS when the whole thing is connected via UART->USB adapter (some seconds). With the RS485 adapter the BMS is recognized almost instantaneously.

By the way, I use two Daly Smart BMS, 150A, 8S with a UART as well as CAN/RS485 interface.

bstrdb commented 1 year ago

@harald0815 did you already solved this issue? i guess i have a similar problem... it my setup it worked serveral weeks with the old driver 0.4. after updating to 1.0 the connection got lost about every second day. @towatai not all daly bms provide a RS485-port :(

harald0815 commented 1 year ago

Hello, unfortunately I could not solve the problem yet. I've already tried an older version of Venus OS and the driver with an earlier version, unfortunately without success. Also a complete reset, other USB to UART adapters, direct USB connection to the Cerbo and various USB isolators, also without getting any closer to the goal. I am currently using my Smart Shunt as a battery monitor again. and the Daly BMS just hangs on for fun. But I've noticed in the meantime that the connection is made again and again after it's broken off. (without restart)

Oh, and unfortunately I don't have an RS485 interface either.

mr-manuel commented 1 year ago

Please post the logs again in the proper format. See Driver log files.

Post the requested logs with the correct timestamp else we cannot help you.

rustyfreeman commented 10 months ago

I have the same issue. Roll back to 0.14.3 fixed it for me.

bstrdb commented 10 months ago

@rustyfreeman interesting... how did you do the rollback?

sinho10 commented 2 months ago

I have the same issue. Roll back to 0.14.3 fixed it for me.

How have you done the downgrade.? In my case my old Hub crashed and nothing worked so I Updated the serial driver and the Venus OS and since then, with the same (new) Hub, i have this issue... A downgrade would be nice to isolate the problem AND i would not cost any money ;)

mr-manuel commented 2 months ago

Please open a new issue with fresh logs, so we can fix the issue rather then do a downgrade.

You would find everything in the docs: Downgrade from >= v1.0.0 to <= v0.14.3

sinho10 commented 2 months ago

Okay i will update everything back to latest gratest and post the Logs in a new Issue.
