How to store the existing value in a array format. Here I have given the charging and discharging limits but it does not check it properly. can anyone help me to sort out this

i_soc=30 %soc charging

% i_soc=90 %soc discharging

ev_a=5 %ev entering time

ev_d=9 % ev leaving time

pevchg=3 % EV maximum/minimum charging power

pevdchg=3

cev=24; % ev battery capacity

for i=1:5

if (i_soc>20 && i_soc<90)

f_SOC(i)=i_soc+(pevchg*(i))/cev*100; % soc charging equation

temp=f_SOC(i)

i_soc=temp

else if (i_soc>90)

f_SOC(i)=temp-(pevdchg*(i))/cev*100 %soc discharging equation

i_soc=f_SOC(i)

end

end

end

f_SOC(i) = i_soc-(pevdchg*(i))/cev*100  %soc discharging equation

May be you mean i_soc instead of temp in discharging cycle

If suppose I have change the i_soc instead of temp in discharging cycle also it does not work. only the charging limit was satisfied .It was exceed the limit and discharging part it won't work sir. can anyone suggest me professors...

if (i_soc>20 && i_soc<90) 
 f_SOC(i)=i_soc+(pevchg(i))/cev*100;  % soc charging equation
  temp=f_SOC(i) 
  i_soc=temp
          else if (i_soc>90)
               f_SOC(i)=i_soc-(pevdchg(i))/cev*100  %soc discharging equation
               i_soc=f_SOC(i)
     end

It seems you are multiplying pevdchg*(i). You need to create array as above for this variable in the loop

[VBBV]

How are these pevdchg and pevchg calculated in your equations inside the if-else condition in for loop ? Can you show what the equations look like ?

[Suganthi D]

In this code I have kept as a fixed value for EV charging and discharging power . so I have written like that ...

From the equation shown it appears that are more variables to be considered. Can you tell what is Tij used as summation? Presumably temperature or timestamp. The code shown also appears incomplete with an extra for loop missing. Pls post full code.
