Louisvdw Posted September 3, 2020 Posted September 3, 2020 I've create the first release for the serial battery driver for VenusOS, with a few steps to install this. https://github.com/Louisvdw/dbus-serialbattery Currently this driver only works on the LLT Smart BMS range. Basicly any of their BMS that use the bluetooth app that looks like this: Dylan and shanghailoz 1 1 Quote
Louisvdw Posted September 8, 2020 Author Posted September 8, 2020 I'm looking for people willing to help with testing this driver for other BMS like AntBMS and Daly. What is needed: If you have a battery that use any of these BMS (or if you have the communications protocol for your BMS) and your battery BMS has either RS232 or RS485 UART for communications. If you use a Victron GX device or built in GX inverter model or Raspberry Pi with VenusOS You need serial communications cable / converter for your BMS (VE.Direct or USB). Buy or build your own. You don't need lots of technical know how, but that might help. (You will need to connect the battery using the serial cable to the GX device and run some Python scripts on there) Send me a PM if you are interested to get involved. Quote

My AntBMS is on the way, once I have it and my pack built I will give you some feedback. Louisvdw 1 Quote
Louisvdw Posted February 8, 2021 Author Posted February 8, 2021 The latest build V0.3 of the driver has been released. With the new version the driver will automatically set your battery max voltage according to the amount of cells in your battery, so it will work out of the box for 4 cells (12V), 8 cells 24V or 15 or 16 cells for 48V setups (or anything in between if your BMS can handle it. it also has an auto installer that works with a USB flash drive/SD card which means you don’t need root access anymore. https://github.com/Louisvdw/dbus-serialbattery Ingo 1 Quote

In your documentation you refer to a USB FT232R connection to the BMS. I assume it's 3V3 opposed to 5V to the BMS correct? Edit: Fixed wrong wording. Edited February 8, 2021 by Ingo Quote

You can use any version (3V or 5V) as this is not used. The cable's circuit is powered by the USB and the Voltage pin of the cable is only if the other side needs power (if you have your own circuit for instance). As the other side is the BMS and it is powered from your battery cells, it does not use external power. For this reason you only connect the Ground, Rx & Tx pins. (see Installation point 2. in the docs) Quote

Louisvdw Posted February 8, 2021 Author Posted February 8, 2021 Hi @smurfdbn I'm currently still busy adding support for the Daly BMS (and hopefully some others there after) so the current version will not work for you yet. The rest of your setup will be fine for this driver. If you want to help with the beta test for the Daly then I suggest you subscribe to the Daly issue to get notifications, or subscribe to the support forum (link in the Readme) Quote
smurfdbn Posted February 8, 2021 Posted February 8, 2021 Hi @Louisvdw Excellent thanks, will do Quote

Louisvdw Posted September 12, 2021 Author Posted September 12, 2021 The latest version of the driver now include support for many more BMS. LLT/JBD / Daly Smart / ANT / JKBMS / Heltec You can find more details at https://github.com/Louisvdw/dbus-serialbattery Quote
