Research on Buoy Power Management Technology Based on the Battery Switch Theory

Abstract:

The cycle performance and the capacity fading model of 18650 Li-ion batteries and the possibility of dual-battery switching technology applied in marine buoys were studied. The recycling capacity fading data of 18650 li-ion batteries were gained and the data were fit by Matlab cttool toolbox. A fitting curve more in line with the scatters was gained. The number of cycles was calculated when the battery capacity remaining 80%. Then the normal working time and the working time using battery switching theory of a buoy were calculated under that specific number of cycles. The results show that the 18650 li-ion battery capacity fading model adheres more to the power function model than linear function model. Its correlation coefficient reaches 0.9811 and it shows a high fitting degree. The longevity of the battery pack using battery switching technology is 28.79% longer than the traditional single battery pack.
