Hello Dear,

Good to know about your interest in interdisciplinary sciences.

Well, if you are looking for a mathematical model for battery storage, you first link with your concepts from electrical engineering. Since the battery is used to store the energy and so the capacitor, hence your model equation will be having a capacitor. Also, no battery can be 100% efficient, it looses some of its energy as heat and hence resistor will come into the picture. Thus your circuit will be having a resistor and capacitor.

Now, you want your battery to give the best performance i.e maximum storage and minimum heat loss. Thus you need to find its optimal arrangement. Also it should have long life and minimum ripple factors. Thus considering these factors one by one you can proceed for a good model design.

I hope it will help you.

Thank you for all answer, My supervisor says that we study on Time Scale. After finish Master I want to go to Germany or Austria for Phd so how can I connect time scale and interdisciplinary sciences subject( Machine Learning, Electrical Car Technology). Whıch subjects(or topics) are popular in the future ?

Study of Transportation Problems using Operation Research

which disciplinary is suitable with time scale? Tıme Scale subject is bright to follow phd in the future or not

This is a very interesting topic. you may find the following journal:

Article Mathematical Modeling and Simulation of an Electric Vehicle

file:///C:/Users/Admin/Downloads/_.pdf

Exact economics.

Econophysics.

The theory of socio-economic systems.

Hello Dear,

I Suggest you

Studies on Geometric Sequence Spaces in Functional Analysis.

Is TIME SCALE good subject for best career PhD in Germany or Austria?

According to your interest you can choose a topic.You can think about Mathematical modeling of real world problems.

One can follow :

Polynomiography, Spectral Graph Theory, Matrix Theory, Combinatorial Theory.
