Heat Generation Rate (W/m^3) to Heat Load (W)
 

Hi,
I'm working on Battery pack simulation and experimentation. I have calculated the heat generation rate (W/m^3) in of battery pack. For experimentation I would like to select the heater capacity in Watts. How to proceed with this?
Please help.
For example the Heat generation rate is 12000 W/m^3. Now I have the volume of battery pack 0.003 m^3. how to select the heating capacity of heater?
