The openBMS project is a legacy repository, nearly 14 years old, which serves as a historical reference for early DIY Electric Vehicle (EV) conversions. With 218 stars and 78 forks, it clearly had utility during the first wave of hobbyist EV interest. However, the zero velocity indicates it is no longer actively maintained. In the modern context, its defensibility is low (3) because the industry has moved toward highly integrated BMS ICs from manufacturers like Analog Devices (Linear Tech), TI, and NXP, who provide their own sophisticated, safety-certified software stacks. Modern open-source alternatives like FoxBMS or LibreSolar offer much higher safety compliance (ISO 26262/ASIL-D), which this project lacks. Frontier labs (OpenAI/Google) have no interest in this domain, but the project is effectively displaced by the consolidation of the BMS market into specialized semiconductor vendors and Tier 1 automotive suppliers. It remains a 3 rather than a 1 or 2 solely due to its value as a structural template for students learning basic BMS logic.
