Planned support​

You can view the current BMS requests to see which BMS support is requested and vote for the BMS you want to be supported.

Add/Request new BMS​

There are two possibilities to add a new BMS.

Add by opening a pull request​

Fork the repository and use the battery_template.py as template to add a new battery. As soon as the BMS works you can open a pull request (PR) to merge it.

Here is a short checklist that should help you:

  • Add your battery class and battery class import in alphabetical order in the etc/dbus-serialbattery/dbus-serialbattery.py
  • Add your BMS to the BMS feature comparison page by editing docs/docs/general/features.md
  • Add your BMS to the Supported BMS page by editing docs/docs/general/supported-bms.md
  • Do not import wildcards *
  • If available populate self.max_battery_charge_current and self.max_battery_discharge_current with values read from the BMS
  • If available populate self.unique_identifier with a unique value to distinguish the BMS in a multiple battery setup
  • If your BMS don't run with the default settings add installation notes to the How to install, update, disable, enable and uninstall docs/docs/general/install.md
  • If your BMS needs custom settings that the user should be able to change, add it below the ; --------- BMS specific settings --------- section in the etc/dbus-serialbattery/config.default.ini
  • Make sure the GitHub Actions run fine in your repository. In order to make the GitHub Actions run please select in your repository settings under Actions -> General -> Actions permissions the option Allow all actions and reusable workflows. Check also in your repository settings under Actions -> General -> Workflow permissions if Read and write permissions are selected. After this changes you have to make a new commit, if you don't see any Actions run. This will check your code for Flake8 and Black Lint errors. Here is a short instruction on how to set up Flake8 and Black Lint checks in VS Code. This will save you a lot of time.

Request by opening a discussion​

Start a new discussion in the New BMS request category. Please add also the protocol documentation which you can request from the manufacturer/seller. The more upvotes the BMS request has, the higher is the priority.

If you would like to donate hardware or would like to help testing a specific BMS please get in contact over the discussions section.
