I understand from your query that it is required to write the equations above in MATLAB to estimate the SOC of battery for fully charged electric vehicles. The following code snippet can be used to do the same.
%declare the constant variables before using them in code
pch=6.6;
enEv=30;
%pre-allocate the SOC vector and x vector size after determination of
%required data points say n
SOC=zeros(n,1);
x=zeros(n,1);
Now code the algorithm you want to implement for determination of SOC in code and write the following equation.
for i=2:n
SOC(i)=SOC(i-1)+x(i-1).pch/enEV;
end
Further information of SOC estimation can be found in the following documentation.
Hope this helps in answering the query.
