The charging control structure and grid impact is studied for peak shaving [ 28 ], for mitigation of power losses and voltage deviations [ 29 ], and for the reduced impact of fast-charging station of EV on a weak grid with a DC fast charging [ 30 ]. The optimal operation such as charging strategy and planning is studied [ 31, 32 ].
However, the work on the cases of simultaneous charging and discharging (SCD) process receives attention in just recent 15 years and is still inadequate. To the authors’ best knowledge, Liu et al. studied an SCD process in a heat pipe heat exchanger with PCM in 2006.
The balanced charging/discharging power is approximately 52 W. By comparison of Fig. 6 and Fig. 8 (b), it can be seen that the balanced power is still lower than that under the equal flow rate. It is noted that the initial charging power decreases to approximately 130 W, owing to the reduction of the charging flow rate.
The variations of the charging power and discharging power are presented in Fig. 6. The variation is mainly caused by the change in the heat transfer temperature difference between the ESU and the water. For an initial temperature of 20 °C, the temperature of the ESU increases, and gradually becomes stable.
To avoid frequent switches between the charging/discharging mode and to keep a continuous operation, TES systems need to be charged and discharged simultaneously. However, the work on the cases of simultaneous charging and discharging (SCD) process receives attention in just recent 15 years and is still inadequate.
Case 1 in Table 4 shows the fully charged EV participating in grid support. In case the EV is fully charged to 100%, frequency control from EV might not be available due to the capacity limitation; thus, full charge is assumed to be 95% of SOC with remaining 5% of EV capacity.
