Simulation Study on Air-Cooled Heat Dissipation for Photovoltaic Energy Storage Modules in Rail Transit

Intensive energy storage battery module is widely used in photovoltaic power generation system of rail transit, and its characteristics such as low cost of air cooling and heating management, high space utilization rate and simple structure meet the requirements of photovoltaic power generation and energy storage system of rail transit. The effects of cell spacing at 25 °C on the thermal performance of dense energy storage battery modules under natural air cooling and forced air cooling conditions are discussed, and the effects of inlet wind speed on the thermal performance of energy storage battery modules are also studied. The results show that the cell spacing and inlet wind speed can reduce the surface temperature of the cell, but the heat dissipation effect decreases with the increase of cell spacing and inlet wind speed. Through this research, it is expected to guide the design of energy storage system in photovoltaic power generation system of rail transit, and provide reference for thermal management setting of energy storage system.
