Abstract :
The paper describes design process and functionality of a portable two-way solar charger prototype, achieving energy density of 571 Wh·kg-1 during a typical 3-day infantry mission. The device may instantaneously charge up to two Li-Ion MR-2791 batteries, supporting plug-and-play operation. The system consists of a lightweight custom solar panel, based on 20% efficient mono-crystalline photovoltaics, and an intelligent power processing module, supporting both maximum power point tracking of the solar panel and multimode charging of Li-Ion packs while instantaneously communicating with the batteries. Experimental results of system testing under real outdoor conditions are presented to demonstrate the device functionality and energy yield capabilities.
