BattMAN - Battery Management with Solar Powered Devices

The BattMan project on battery management for solar-powered devices designed and developed battery-pack systems that manage photovoltaic power feed efficiently and deliver optimized, reliable, low-cost, and predictable performance. Batteries and battery management systems were employed in various applications. The project focused on connectivity between solar-powered, off-grid street lighting poles using local batteries for off-grid powering.

The BattMan project's outcome was the development of a novel intelligent charge controller designed for off-grid street lighting, using a new MPPT algorithm that helps overcome the drawbacks caused by rapidly changing environmental conditions. 

The solar-powered outdoor street-lighting system working in cold climates is one of the exploitation routes using LiFePO4 and Li-Ion battery packs with BMS reference design for 24V and employing a CAN bus interface. 

The communication between the lighting poles was designed using low-power RF modules based on sub-gigahertz radio communication, with integrated voltage regulation, antenna, crystal, and microcontroller.
