On February 7, 2025, the IEEE Std 2686-2024 Recommended Practice for Battery Management Systems in Stationary Energy Storage Applications was published. This recommended practice describes battery management fundamentals, including best practices for its design and configuration. It outlines the hardware and software architectures commonly used in battery management and provides a list of battery management functions applicable to different batteries in various applications. Additionally, it offers recommended communication structures and data models that support interoperability and cybersecurity. The result is a comprehensive list of best practices for the design and integration of battery management systems that protect the safety and longevity of batteries in energy storage applications. This work enhances the reliability and security of battery systems while reducing integration costs for batteries on the grid, ultimately leading to lower energy prices and increased resilience of power systems.
IEEE is a standards development organization that publishes technology standards widely used around the world. Sandia researcher David Rosewater has led the standard’s IEEE working group since its formation in 2018 to build consensus across stakeholder groups, which comprised nearly two hundred stakeholders from various industry sectors.
