Never mind! It seems like the entire model is functioning now, if anyone else has this issue the solution seemed to be to use a different time model like I showed above. After that I just fixed a s...

Thank you, I understand. I suppose my final question would be: I have checked the lp. file, and my constraint  def battery_test_rule(model,t):       return model.batteryLevel[t] == model.batteryLe...

Thank you very much, I implemented the changes you suggested, but it sadly still does not give any values for the batteryLevel model What do you mean by "the line is checked"?  My thoughts were t...

I want it to make sure the line return model.batteryLevel[t] == model.batteryLevel[t-1]+model.batteryCharge[t-1]-model.batteryDischarge[t-1] is checked for every t in my model, with the exception t...

What do you mean exactly? These are just a part of my model, I have several constraints following this setup and they seem to work?

Okay, I am suspecting that the errror is due to the fact that the "battery" can both charge and discharge at the same time, so I will try to fix thatThank you very much for your time!

Thanks! That fixed the keyerror! However my  model.battery_level values do not change, they stay at 1000  which is the upper bound  def battery_level_rule(model,t):                                 ...

What is the best way to express this in the constraint format? 

# Set representing the time steps, 48 hoursmodel.t = Set(initialize=np.arange(0, 48), ordered=True)# Set representing the time steps until all vehicles must be fully charged, 32 hoursmodel.c = Set(...
