When I choose to simulate temperature effects of battery, it takes too much time to simulate

I am trying to simulate the battery performance during charge and discharge and when I choose to simulate temperature effects of battery, it takes too much time to simulate. I am now working with a variable-step solver with automatic solver selection ans a Continuous powergui block. I tried to change the solver type and the relative tolerance but the simulation still slow.

R2019b

Simulating battery temperature effects in MATLAB R2019b can be slow because it adds thermal-electrical coupling, making the system stiff and computationally heavy. To improve performance, try switching to a stiff solver like ode15s, increase the relative tolerance slightly, and set a reasonable max step size. Simplifying the thermal model or using a discrete powergui block can also help.
