The new foxBMS software release is available on GitHub.

We publish major software releases for our open source BMS platform every 3 to 6 months and interim bug fixes when solved in the News section. By subscribing to the foxBMS Newsletter, you will be informed when the new releases are available. Further, the foxBMS Roadmap and the Documentation are also updated regularly.

Warning: The foxBMS hardware and the foxBMS software are under permanent development. The free and open research and development platform foxBMS as presented in the documentation hereafter is not provided to be used without any adaptions (e.g., to fulfill mandatory regulations) in consumer products, electric vehicles, production environments or any similar usages: it is only intended to be used by skilled professionals trained in designing battery system prototypes.

Release notes:

We fixed a bug in the ltc driver, leading to a non-functional temperature sensing for foxBMS Slave Hardware version 1.xx. The slave version is configuration in srcmoduleconfigltc_cfg.h by the define SLAVE_BOARD_VERSION.

  • Set SLAVE_BOARD_VERSION to “1” if you are using version 1.xx of the foxBMS Slave.
  • Set SLAVE_BOARD_VERSION to “2” if you are using version 2.xx of the foxBMS Slave. Version 2.xx is the default configuration.

We added more useful error messages during the bootstrap step, in case something is not working as expected.

  • foxBMS-primary
  • fixed LTC temperature sensing bug
  • foxBMS-secondary
