How to catch the abnormal situation during battery operation by Petlion

[lico0001]

Hi MarcBerliner. I want to catch the outlier during battery operation, that is, if the temperature is set too high, the current and voltage will change abnormally during battery operation. BBut in my previous attempts, if I set it this way, the program would report an error. May I ask if this data can be obtained through Petlion? If so, is there a suitable example? Looking forward to your reply, thank you.

To clarify, is your simulation failing at high temperatures but you still want to receive the output?

Yes, but what I want to know more is how to get the outlier through the status of the Petlion battery crash.

This isn't explicitly accounted for, but there is a workaround. Say you want to run a CC-CV simulation

p = petlion(LCO)

sol = simulate(p, I=5, SOC=0)
simulate!(sol, p, V=:hold)

which crashes with the message

julia> ERROR: Model failed to converge at t = 101.5279999999999

To save the output, first initialize the solution object sol and enclose your simulation loop in a try/catch block. The solve still fails, but you can access the final states before failure.

sol = solution()

try
    simulate!(sol, p, I=5, SOC=0)
    simulate!(sol, p, V=:hold)
catch
    # input catch here
end
