3. Combining energy harvesting sources for increased system availability and using an input switching algorithm to maximise battery lifetime
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : Energy harvesting is commonly used for powering low power electronics, for example Low Power Wide Area Networks (LPWAN). Many energy sources are natural (e.g. solar or wind), thus the harvested power can depend on weather, time of day, and time of year. READ MORE
