soc estimation for fully charged Electric vehicles

SOC(i) = SOC(i −1) + x(i −1). pch / enEV .

pch=6.6; % charging/discharging power

enEV=30; % battery capacity

i dont know how to write this equation in code..

could you please help me how to write this equation in matlab code

Hi @Suganthi D,

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.
