Battery State of charge estimation

I am currently building a battery model to measure the state of charge of the battery (Lithium Ion with 48V and 20Ah). The battery is used in an electric vehicle and I am trying to monitor the SoC.
However, the battery has no datasheet!
Is it possible that I could estimate the state of charge?
If so, how the project going to work? I mean, am I going to work on the model and then convert it to a C code and deploy it on an embedded device?
I also need some guidance on how to start working on this project.

Hi Ahmed,
Simulink is a platform for modeling both plants and algorithm.
If you have model of your algorithm, it can be convert to C code. You can use it in your embedded device.
If you can build battery model in it, then you can combine algorithm and battery, use algorithm to estimate SoC of battery.

You can estimate battery SoC by measuring battery terminal voltage.
