A thermal management system for an energy storage battery container based on cold air directional regulation

The existing thermal runaway and barrel effect of energy storage container with multiple battery packs have become a hot topic of research. This paper innovatively proposes an optimized system for the development of a healthy air ventilation by changing the working direction of the battery container fan to solve the above problems. Four ventilation solutions based on fan flow direction control are numerically simulated, and their internal airflow distribution and thermal behavior are analyzed in detail. The results show that the heat dissipation effect of optimized solution 4 is significantly better than other solutions, and its average temperature and maximum temperature difference are 310.29 K and 4.87 K. The results are reduced by 1.16 % and 54.36 % respectively compared with the initial scheme. The results show that optimized solution 4 has significantly better heat dissipation than the other solutions, with an average temperature and maximum temperature difference of 310.29 K and 4.87 K respectively, a reduction of 1.16 % and 54.36 % respectively compared to the initial scheme. In summary, the cooling and ventilation solution based on the logical control of the fan direction is feasible and had a certain market prospect due to its simple structure and high economy.
