Comments to the Authors
Authors must standardize the dimension of the result graphics. The font sizes on both the x and y axis must be increased. Authors must identify the x axis in all result graphs.
To Reviewer 1:
Thank you for your review and valuable remarks. All figures have been redrawn with wider fonts and named X and Y axis.
Reviewer 2 Report
- Please carefully review the manuscript and make the manuscript better readable. e.g., 1) in page 5 line 120, "than" should be "then". 2) In page 5 line 125 to 127, the sentence is too long and it is not very easy to understand. 3) from Figure 15 to figure 17, there is no axis titles for all of them. 4) the flow of the presentation should be improved, it was more like a tech report but not a manuscript, as there is no good connection between each section.
- Could there be any schematic but not the actual simulink implementation for the figures? especially the signal connections (inputs/outputs) between the vehicle and the household?
- what is the ripple for red line in Fig. 15? any idea why it happens?
- how to set the PID parameters? Will it affect the system performance in fig. 15-17? what has been considered when determining the PID paras?
- what is the potential power loss (like thermal power loss) that will usually happens in the full/half bridge?
- for Fig. 11, a flow chart would be much better than the simulink implementation, same as fig. 7.

2. Simulink allows only of unidirectional signals, so the block diagram shows the connections. This is a system level implementation, so the individual connections can be traced if one so desires but not the principal idea.
3. what is the ripple for red line in Fig. 15? any idea why it happens?
3.1 There are possibly two factors:
1) This is due to the size of the maximum power limits set for the power converter connected to the battery and the one connected to the EV.
The problem is as follows: the converter charging the EV, when active consumes constant current to charge the battery let’s say PEV. Depending on the available energy (Pacref- Phousehold) the difference can be larger or smaller than PEV. When larger, or the battery is charged to 100% SOC no such ripple happens. This is due to the fact that the BB converter also has charges its battery. However, when the available is positive and less the PEV the EV is charging, with the leftover power coming from the discharging BB (at least from the algorithm implemented). As the limit set for the maximum power that this converter can source was set to a value lower than the maximum power that needs to charge the EV moments happen when power needs to come from the ac more than the reference value in order to obtain energy balance. This was easily visible when the converter was simulated with lower limit for PEV than the battery bank (in other words the power converter attached to the battery bank has a higher maximum power limit). The results are shown in the attached file and the edited version of the manuscript.
2) Second reason (as there is some small ripple left over especially at the moment around 8x10^4) is due to the fact that probably some tweaking of the step size and/or the PID coefficients may be necessary.
4. how to set the PID parameters? Will it affect the system performance in fig. 15-17? what has been considered when determining the PID paras?
4. They will, but this is not important as far as the overall system level algorithm is followed in predetermined limits. Detailed analysis of how to design such a system (with the tuning of the parameters) are not part of this paper
5. what is the potential power loss (like thermal power loss) that will usually happens in the full/half bridge?
5. In order to have data on the potential power loss detailed power converter models must be simulated, not the used average models. This can be done, but it is not in the scope of this paper where a system level model that can be simulated for a large time interval is the primary goal.
6. for Fig. 11, a flow chart would be much better than the simulink implementation, same as fig. 7.
6. A flow chart has been added discussing the basic operation of both converters (battery and EV). A Flow chart approach is not adequate for a UML modeling of the algorithm of figure 7.

Round 2
Reviewer 3 Report
The authors should be improved the figures, size, colors and quality.
This study should be compared with other similar work, to indicate innovations
The conclusions should be clear and concise and therefore be improved, and add data from the tests carried out

The authors should be improved the figures, size, colors and quality.
Thank you very much for the comments and notes. We reviewed and edited all the figures again.

The introduction and conclusion sections have been edited.

The introduction and conclusion sections have been edited. At present, conducting practical tests is difficult due to the lack of complete equipment, which we expect by the end of the year. On the other hand, a comparison of the results with other manuscripts and the balance of power show that we have every reason to assume that the results are reliable.
