Simulation analysis and research on the heat dissipation spacing of the energy storage battery module

An electro-thermal coupling simulation from cell to module is performed using Gotion lithium-ion batteries under natural convection, deriving heat-generation data. Testing confirms the hottest busbar as the temperature sampling point. Subsequent simulations analyze how battery spacing and ventilation impact cooling, based on heat-generation results and module design. The final cooling solution implements 8 mm battery spacing, a 12 mm central air duct, and forced fan ventilation.
