Its time to provide your valuable feedback on another potential Open Source innovation: Open Source Flexible Battery Management System for off-grid energy storage. One of our core evaluation criteria for every innovation solution is to understand if the proposed innovation is addressing the sector level need. We decide this based on your interest to adopt such solutions in your business operations, should this solution get funded and available as open source.
Share your feedback directly in the forum here for everyone to see and participate.
These are the questions we are trying to answer:
- Would the list of deliverables be sufficient for you to adopt this innovation?
- How disappointed would you be if we did NOT go ahead in developing and open sourcing this innovation?
e.g. Very disappointed, Somewhat disappointed, Not disappointed
- Can you share potential scenarios when this innovation would NOT work for you?
Anything else we should know?
Open Source Innovation:
Productive use appliances like milling machines as well AC microgrids require safe, reliable and powerful Li-ion/LiFePO4 batteries . This project will develop a modular and fully open-source Battery Management System (BMS) for 12V, 24V or 48V systems (up to 16 cells in series) and continuous currents of up to 100A. Multiple battery/inverter units can be connected in parallel to flexibly increase the power.
The deliverables will include all documents to rebuild, manufacture and integrate a battery including the developed BMS:
- Electronics hardware (schematic and PCB design made with KiCad)
- Heat sink and plastic enclosure design (made with FreeCAD)
- Embedded software (based on existing Libre Solar BMS firmware and Zephyr RTOS)
- Software to communicate with the device via mobile phones or computers (payment system integration, diagnostics, configuration, remote management)
- Cloud integration via MQTT protocol
- User Manual containing extensive documentation of all features and functions
