SoC and energy balance using PyBaMM

[Chavan073]

Hello! I just started using PyBaMM and am trying to model a battery and plot the SOC over a 24-hour day. I am pulling data from a load profile I created in Excel (Time and Load [kW]). The model should step through the day in 30-minute intervals and plot the results.

My issue is when I check the energy balance, the numbers are a bit wack, and I’m not sure how to interpret them. I have written a similar program without the PyBaMM library and get more sensible results on the same data, so I am not sure what I am doing wrong. Any advice would be greatly appreciated!

These are the results of my energy balance:
Initial Energy: 5000.00 Wh
Total Energy Used: 40750.00 Wh
Total Energy Lost (Efficiency): 4527.78 Wh
Final Energy Stored: -40277.78 Wh
Expected SOC: -805.56%
Final Simulated SOC: 0.00%
