Matlab simulation expert

I am working on this project to extend battery range of electric truck using only renewable resources.

I have tried to get details from truck manufacturers to design the truck but couldn't get any. So I don't have any design details. But my requirement is an electric truck model in MATLAB

So I will need you to do an electric truck model

second model is with some modifications, to increase truck range

I need to be able to simulate the truck model to check battery range before modification and after.

Also I need you to explain the model and coding to me since I will have to show it to my mentor

My final thesis is 15k words but i can write that one myself

1. Basic electric truck model - matlab code and simulink model

2. Explaining me the model and code

3. Modifications to model according to mentor's suggestion - Maybe 3 to 4 modifications.

4. Report
