fix daly can init problems

[transistorgit]

Hi Manuel,

your latest can cleanup introduced a problem that the daly can bms was not found or found only after 10 or so tries.

• I moved the jk bms stuff into an "if" clause, as there is no data from daly available until the first request
• I wait for the can_bus instance comming up by syncing with the thread. There were problems , as your new can init seems a bit slower

best regards
Bernd

hi, as I'm still waiting for the new bms, I've made a daly can simulator. So I was able to implement the can-parallel stuff. It can handle multiple dalys on multiple can busses. and, we can test it without hardware. this may be the first step to pipeline integration steps 🙂
(btw: chat gpt wrote 98% of the simulator)

the 72% SOC bms is my physical device, the others are simulated

the cell voltage id hack makes the code very ugly. I propose to change the message cache into a time based id. this is how me make in in professional projects also. the cache key can be a tuple of can ID and timestamp. Then we can make the appplication code much cleaner

Very nice! Could you please move the folder test outside of dbus-serialbattery? Else it's shipped with the driver on release and this is only needed for development.

Hi,

I have received my 2 new Daly BMS's today and all the tests have gone well. I was able to connect 3 devices to one can bus or also on 2 can busses. Mixing serial and can devices doesn't work, only can is detected then. I'haven't investigated that, as this is possibly not needed.

Daly has releases a new bms series with internal 1A active balancer. These are blue now, not red. Also the app looks different, and you have to use a new PC configuration software (for changing the device address). They even have a new branding called "100balance"... very confusing for new users.

Probably you should note that on the documentation page.

Could you please post a screenshot and instructions on how to change the device address in the new software?

• Download new Software from here: https://www.100balancebms.com/en/download.asp. Choose "PC Host Programm for BMS"
• Unpack it and start the JHB_serialport.exe. Windows may prevent this, override it.
• Now the screen looks like this
• open the connection by choosing the right connection. I tried to use my Peak CAN USB dongle, but that don't work with this version (you can use the "older" daly "BMSTool-V1.14.23" software, that worked for me also, but is a bit more complicated. So if you don't have a proper CAN adapter for your PC, use a RS485 adapter and choose it from the serial port selection. Keep the baud rate at 9600
• Now you should see live values from your battery
• Select "Engineering" from the left menu. There you can find the board address setting at top right
• Input your desired address and click "set". A green tick should appear. Thats all.
• Go back to the Main screen. Select your board number from the address selection at the top and you should see the live values again
• you can close the program now

Nice, thanks!
