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.
