foxBMS 2

foxBMS is a free, open and flexible development environment to design battery management systems. It is the first modular open source BMS development platform.

Overview

foxBMS is an universal hardware and software platform providing a fully open source BMS development platform. foxBMS aims to control modern and complex electrical energy storage systems of any size. foxBMS is successfully used for electrical energy storage consisting of

• Lithium-Ion and Solid State Batteries
• Lithium-Sulfur Batteries
• Sodium-Ion Batteries
• Lithium-Ion Capacitors (LIC)
• Electric Double-Layer Capacitors (EDLC, supercapacitors or ultracaps)
• Redox-Flow Batteries (RFB) (e.g., Vanadium Redox-Flow), and
• Fuel Cells (FC)

or in an hybrid combination of these and in various domains.
