I used generic battery model first as it provides battery age as output but I feel it is not providing cell temperature correctly

Hi @Jarin Tasnim, I'd suggest you to show the math model of the battery (in differential equations).

If there are block diagrams, images, preliminary data plots, then they are also useful for the investigations.

Hello Jarin,

Thank you for your question.

The Battery (Table-based) block (Simscape Battery or Simscape Electrical) computes battery usage calculating the throughput in equivalent full cycles. The variable name is num_cycles and you can access it using a Simscape probe.

For the thermal simulation, please make sure you parameterize the thermal mass correctly. Thermal mass is the product of the specific heat and the cell mass. The former is sometimes hard to find. Please see this publication for reference: ICES_2016_9.pdf (tdl.org)

Hope this helps.

Best regards,

Javier
