Support BMS DR-JC03? #327

Closed andkirby closed 1 year ago

andkirby commented 1 year ago

Describe the bug I'm trying gather all things together for: Victron MultiPlus 48/5000/70 + Cerbo GX + Battery LiFePO4 with BMS DR-JC03.

I've installed your app, and connected Cerbo GX-USB <-> USB-RS485 Adapter with 3 pins (A/B/Ground) <-> RS485-RJ-45 on battery

On RJ-45(RS485): 1- RS485B 2- RS485B 3- GND (I made this according to this manual. It's not so suitable, but didn't find better.)

Am I wrong somewhere?

To Reproduce Steps to reproduce the behavior:

  1. Go to Cerbo GX terminal
  2. Install dbus-serialbattery
  3. Connect the battery
  4. See logs: tail -f /data/log/dbus-serialbattery.ttyUSB0/current
  5. See error 
    ERROR:SerialBattery:ERROR >>> No battery connection at /dev/ttyUSB0

Expected behavior Logs shall show success connection.

Louisvdw commented 1 year ago

This is not a BMS that is supported by die driver. I cant's find any communication protocol information on their website, so I can't say if it would be possible to add.

andkirby commented 1 year ago

Hi @Louisvdw , Thanks for your quick response.

But how these 3 wires to RJ45 (RS495) shall be connected to a battery via RS485/RJ45? Is there some standard or something?

As the solution 1-A+ / 2-B- / 3-GND does not work, I found this adapter USB-RS485/RJ45 https://www.amazon.com/RS-485-Adapter-Serial-BCBL-01-Communication/dp/B08GLFBTZW

According to the picture: Green-GND, Red-A+, Black-B-. image

So, on RJ-45(RS485): 1) GND 6) RS485 A+ 7) RS485 B-

Error No battery connection at /dev/ttyUSB0

That's a web page of a similar battery like mine: 512KWH-48V-lifepo4

Louisvdw commented 1 year ago

The wires does not matter if the driver does not talk the language of that battery. If this battery can do CANbus you might not need the serial battery driver.

andkirby commented 1 year ago

I got no CANbus input, unfortunately. image

The wires does not matter

But I have to establish right connection first, right?

Louisvdw commented 1 year ago

Yes, you do need to get the correct wire connection first. But there are no standard for that. You will have to check your battery manual which pins are used. But even if the correct pins are used and the connection is valid, the driver will not know how to talk to this battery unless it use the same BMS as one of the supported BMS.

andkirby commented 1 year ago

But there are no standard for that.

That's a shame :(

You will have to check your battery manual which pins are used.

No manual from XD battery vendor. :( 🤦

Thanks for this note, L!

andkirby commented 1 year ago

Contacted with XD Battery company. I was told, it can be connected with their battery (w/o programming). They promised to help to make it work. My hands are itching to see the manual. I'll bring updates...

joggl commented 1 year ago

Diese Batterie funktioniert mit dem Treiber nicht. Du musst folgende Dinge ausführen. https://we.tl/t-pgNDHMLJ7y (the link for the battery manual, pc software, BIN code , upgrade video) 1.upgrade the battery by the BIN code first. 2.battery connect victron by CAN bus (the RJ45 cables PIN change for CAN) 3.master battery dip 5 and 6 on 4.victron setting pylon working model

andkirby commented 1 year ago

@joggl, thanks for the answer. Why it's not in english (completely)? :-/ What this link about? I see "Introducing portraits". I guess, you added wrong link.

1) Didn't get it. What does "BIN code" mean? 2,3) Yes, 5 & 6 pins must be up. For some reason it works only via CAN bus which is configured as BMS CAN.

That's the answer from the battery vendor. This manual helped me to connect my battery. image

Probably, will add detailed manual later.

joggl commented 1 year ago

Hello andkirby, i am from Germany, i try to write in english. I have a battery with the same BMS from an other battery maker. The program from louis doesn't work with this BMS. In the delivered version of my battery the BMS can not comunicate with victron and I have to install an Update on my battery ( this means bin-code). In the link are the updatefile, a PC-software to bring the update on the battery and choose some settings, a movie who show the way of update and settings and a manual (PDF). I had to go this way and now my Raspberry Pi with venus os comunicate with the battery. Best Regards

andkirby commented 1 year ago

Hello @joggl,

it looks like you did a piece of work!

So, the link either is broken or invalid or not allowed to see from my side. I see the following:

Transfer expired Sorry, this transfer has expired and is not available any more

I assume, something went wrong... =) Maybe you have another source of this video.

My questions to your comment:

  1. Where this update (installed on your battery) is coming from?
  2. How to did you install it?
  3. Which version do you have now?

BMS can not communicate with victron 4) It somehow communicates with my Cerbo. Does it work via BMS Can on your side? I have "Settings > Services > VE.Can port > Can Bus profile" = "CAN-bus BMS (500 kb/s)".

joggl commented 1 year ago

This is the manual of my battery. The update for my battery I get from my seller. I only connect 2 cables on my can-hat (CANH and CANL -> Pin 4+5). IMG_20230129_211846 NEW-48V LIFEPO4 BATTERY USER MANUAL.pdf

I don't understand how i can do the Video in GitHub. So i do it this way .

I'm not allowed to commit directly, but this here seems to be an older version of the protocol: https://www.photovoltaikforum.com/core/attachment/77134-pylon-lfp-battery-communication-protocol-rs485-v2-8-20161216-pdf/

Hi. After all of this information i still have a question :) I am using a raspberry pi with venus OS. So this type of bms works only with waveshare can pi hat ? I have a USB -Rs485 adapter and i failed to connect this bms with raspberry pi. So i have to buy a waveshare can pi hat ? The adapter i use right now is the one in the picture, please see the link down below. Thanks.

@MarzaBogdan i have only been able to run it with a pi Hat on the venus os, but technically it should also work with a RS485 USB adapter - but I haven't seen this yet.

I have to install or activate any driver on venus os ?

This pi hat from waveshare runs without any additional drivers on venus os.

Ok thanks, I will try again with my rs485 adapter and if it still not working i will buy that pi hat waveshare. The thing about my rs485 adapter is i have only 3 ping A B and GND. On wave share i see H L B A.

Thanks for your quickly response

joggl commented 1 year ago

For me it only works the can hat too. I have to Insert a few words at config.txt. See on waveshare wiki. https://www.waveshare.com/wiki/RS485_CAN_HAT

Yes. It is working for me too. Today i was able to connect the battery to the venus os. Thanks
