Hello Respected,
I try to simulating the change of temperature of a battery, change with temperture and time, current discharge (0.5C).
After the simulation, the battery temperature drop did not match the expected results.Actually, the battery temperature should rise.
I don't know where the problem is, please help me, thanks.
