Adding SOC to Existing MATLAB Simulink Model

I need a Simulink model needs to be upgraded. The existing model contains a battery. I wanted the model to use AEFK algorithm to predict battery SOC. I expect the freelancer to add Adaptive kalman filtering technique (AEFK) to the model to estimate the Battery State-of-Health.

Reference model:

The battery model is attached below.

NOTE: ONLY ELECTRICAL ENGINEERS ARE PREFERRED
The selected freelancer also have the choice to work for long term commitment. In that case, they should have the potential to undertake 2-3 such small and intermediate level projects per month
