Description
Summary:Lithium-ion battery energy storage cabin has been widely used today. Due to the thermal characteristics of lithium-ion batteries, safety accidents like fire and explosion will happen under extreme conditions. Effective thermal management can inhibit the accumulation and spread of battery heat. This paper studies the air cooling heat dissipation of the battery cabin and the influence of guide plate on air cooling. Firstly, a simulation model is established according to the actual battery cabin, which divided into two types: with and without guide plate. Then, at the environment temperature of 25°C, the simulation air cooling experiment of the battery cabin was carried out. The working condition of module was 1C, and the air speed was set to 4m/s. The results show that the average temperature, maximum temperature and temperature difference in the battery cabin reduced by 4.57°C, 4.3°C and 3.65°C respectively when guide plate added. The air cooling effect of battery cabin was improved by adding guide plate. There is better consistency between the modules and the modules can operate at more appropriate environment temperature.
