I is better if you define your parameters, Wh, cost

What dou you want exactly to do? Before building the model, you have to know that depending on the vehicle model, they have different kind of batteries, so you have to search their specific parameters.

Thanks for your answer ... I must add that the parameters are specified in paper. But I have problem with the way to relate these parameters together to build the mentioned model in SIMULINK.

To use a battery with photovoltaic panel, you should take care of the out put voltage of the dc-dc converter. you can apply an MPPT algorithm with constant voltage. in addition to that you should indicate how you will integrate this battery on your system to fix the choise of the dc dc converter(4 quadrants or 2 quadrants)
