Cell balancing of Li-on battery

Hi,

I am trying simulation of battery behaviour of lithuim ion battery. In simulation total 6 batteries are connected in series and parallel. once cell balancing are used, i can't get output of aging and temperature. I have used battery block from simscape. Let know problem or example of battery aging with cell balancing.

can you share your model? This is not enough information to help you.

Hi,

Please find the model I have used for aging.

Hello Nalla,

When I run your model I can see the temperature output (please make sure you enable temperature effects) and the cycle count equal zero means that the simulation time is far too short to show significant aging. Please keep in mind that the cycle count is equal to one once the integral of the current in absolute value is equal to twice the capacity. In your case, C = 2.6 Ah, which means that one cycle will be counted once 5.2A have passed through the battery for one hour, which is much longer than what you have set.

Please let me know if this clarifies the issue.

Best regards,

Javier

Hello Javier Gazzarri,

Previously I have tried with enabling temperature and aging but I can't get number of cycle. In simulation

battery starts discharge before battery reaches 100% SOC.
