Formation process through charge/discharge operation is needed in manufacturing Li-ion battery. In the process battery is discharged by a load resistor of discharger. Here, energy losses happen. Therefore, in this paper, the efficient energy operation of battery is studied in the charge/discharge system based on DC μ-Grid. A result of computer simulation shows that if in the charge/discharge system based on DC μ-Grid, the number of discharge batteries in comparison with three charge battery sets exceeds 133%, voltage fluctuation that occurs while the grid voltage stabilizes, which makes the system fatal. Therefore, it was demonstrated that a remarkable energy saving effect could be achieved when the number of discharge battery set is maintained to be 133% in comparison with three charge battery sets. |
