cut_off voltage is ignored in experiment

[masoodtamaddon]

Hi

I have tested two different scenarios: one discharge using Experiment and another discharge using the imbedded current profile (e.g. for Yang2017 DFN model) and noticed that when I use Experiment, the cut-off voltage is ignored in the solution. Is there anyway to work around this issue?

See the following script:

import pybamm as pb
import numpy as np

model = pb.lithium_ion.Yang2017()
param = model.default_parameter_values
param.update({"Lower voltage cut-off [V]": 3.5} , check_already_exists=True)
output_variables = ["Current [A]", "Terminal voltage [V]"]

test1: discharge using experiment

exp = pb.Experiment(
[
"Discharge at C/1 for 1 hours"
]
)

sim_exp = pb.Simulation(model,
parameter_values=param,
experiment = exp,
solver=pb.CasadiSolver(mode="safe")
)
solution_exp = sim_exp.solve()
sim_exp.plot(output_variables=output_variables)

test2: discharge using param

t_eval = np.linspace(0, 3600, 100)
sim = pb.Simulation(model,
parameter_values=param,
solver=pb.CasadiSolver(mode="safe")
)
solution = sim.solve(t_eval)
sim.plot(output_variables=output_variables)

To specify a cut-off voltage in the experiment you have to do "Discharge at C/1 for 1 hours or until 3.5V" or "Discharge at C/1 until 3.5V"
