The foxBMS 1 version 1.0.2 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 platform including 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.

Based on all the feedback received during the last 2 years from foxBMS software partners and users, the embedded software and the computer software have been restructured to provide a clearer structure and allow enhanced flexibility.

Release notes:

  • One error in the ISOGUARD module and one error in the EEPROM module have been fixed in foxBMS 1 version 1.0.2.


  • fixed a bug in ISOGUARD module that caused a wrong insulation resistance to be transmitted via CAN if the measured insulation resistance was greater than 255kOhm
  • fixed a bug in EEPROM module that overwrote EEPROM data with default values if EEPROM header was corrupt
