Week 5 Battery characteristics using drive cycle

Objective: To simulate a generic battery model discharge using UDDS drive cycle data.

Explanation: Since we are simulating the model with Drive cycle data for an EV vehicle, one Lithium battery cell wouldn't be sufficient. With reference to a research paper (MATLAB SIMULATION MODEL FOR DYNAMIC MODE OF THE LITHIUM-ION BATTERIES TO POWER THE EV) Calculations of the EV model are based on the i-MiEV vehicle, where the nominal voltage value battery pack is equal to 330 V. The battery pack is composed of 11 series-connected modules with the 8 battery cells in parallel with a nominal voltage of 3.75 V.

As we are considering the EV vehicle, the current value is also considered as 50 A.

Matlab Script:

The UDDS drive cycle data is fed into the Simulink block using "From workspace" block. This data was taken in an excel file and converted into ".mat" format.

Results:

i) Based on the graph it is observed, the battery charge is charged is completely drained by 900 seconds.
