Project 5
AIM
The Aim of this project to make a Battery model that can simulate the Aging effect of battery and observe/comment on Aging of battery in different temperature, charging/discharging rates of the Battery pack.
Battery Model with Charging, Discharging and temperature effect:-
In this Project we Design Battery Pack 10 cells In series Then we take Diffiernt Dicharge and Charge Condition How to work our battery pack and also obervation on the diffierent Ambient Temperture we try find how results wiil come
Now we see the battery Pack Arrangemnt we take Generic battery cells with 7.2 V and 5.4 Ah
We create Sub system For this Battery Pack Other think we Show below + and - terminal goes outside connect with Control current sources and Given inpute to Current Control cells is We create one Chart in That we create Graphical Logic and we also we tick mark to temperture and aging effect so we try diffiernt temperture how cells work
All cells parameter we take Default we take 10 Battery In series so the volatge of battery is 7.2*10 current is the 5.4 Ah
Now we first try For the Ambient Temperture 20c and for 20 hours and Charging is -5.4 (Negative) and Discharging Current is 5.4 Now we simulate and see the result
we see the result in that volatge we can see SOC and charging and discharing current
After the thermal and aging effect on battery
This Graphical Logic use For the battery Charging and Dicharging Current
Now we first try For the Ambient Temperture 40c and for 20 hours and Charging is -2.4 (Negative) and Discharging Current is 2.4 Now we simulate and see the result
we see the result in that volatge we can see SOC and charging and discharing current
After the thermal and aging effect on battery
Volatge and Current Block Due to we are cells conncet in series so our Volatge are increses and current reamin same
Conclusion:-
We can conclude that the Age of the Battery pack will effect by Temperature, Charging rate and Discharging rate. Lower value of the temperature, charging rate, discharging rate will results in reduced aging effect of battery pack and Higher life cycle can achieved. but the temperature of the Battery pack can effect the capacity of the battery independently, but its not permanent as the capacity of the battery recovered with the increase in temperature, although aging of the battery is irreversible.
