Abstract:A scheme and operational strategy of wind cooling thermal management are designed to investigate the thermal management method and operational scheme of the retired power battery energy storage and reuse process. This is based on a retired lithium-ion power battery energy storage system. The mathematical and physical model of the retired battery cluster in the cabin is established. The temperature distribution of the LFP battery and NCM battery clusters under different wind rates is simulated, and the thermal behavior of the battery cluster with and without wind cooling strategy is compared and analyzed. The results show that wind cooling thermal management can meet the temperature range suitable for the normal operation of retired power batteries. For LFP and NCM battery clusters, the maximum temperature difference of batteries in the cluster can be reduced from 10 K to 4 K under the condition of without air cooling and with air cooling respectively, and the maximum temperature rise of batteries can be reduced from 30 K to 10 K. This study can provide a reference for the efficient thermal management of retired power battery energy storage systems.
