However, in the nighttime, the plant''s net energy output is higher in the fast charging mode, as the plant''s operation period lasts an extra 1.5 h. According to the results in Fig. 11, the slow charging mode decreases the plant''s daily net energy output over March 17 by 7% compared to the fast charging mode.
