Two rows of battery cells are arranged side by side in the shell, the battery cells 4 are arranged front and back, and a heat sink is arranged between the battery cells. The air duct 5 between the battery cells and the two sides of the shell transports the cold air from the air inlet to the side of the battery cell 4, and then transports it to the air duct 6 between the two rows of battery cells through the heat sink 7, and finally discharges the air from the air outlet in the middle of the front end of the shell. The heat dissipation holes in the middle of the heat sink can reduce the temperature of the battery cell, and the hot air after converging is taken out of the box through the front fan. The battery module is the smallest unit of the energy storage battery cluster, and has air inlets on both sides, and heat sinks 7 between the battery cells, forming an air-cooling circuit with air inlet on both sides and air outlet at the front. The fan arranged at the middle air outlet at the front end of the shell can adjust the speed according to the temperature of the battery module, so as to achieve the purpose of adjusting the cooling effect for each battery module separately. The heat sink between the battery cells is provided with heat dissipation holes parallel to the battery cells, and a heat conductive layer is also provided between the heat sink and the battery cells, and the heat conductive layer can be silicone grease.

[0017] A temperature sensor is installed in the battery cell area at the air inlet of the battery module. By detecting the temperature, the temperature information is summarized and sent to the control system for unified processing.

[0018] The battery module adopts an adjustable air-cooled heat dissipation structure, which has significant advantages. Its closed shell design can effectively improve the air cooling effect while ensuring the safety and stability of the battery module. The air inlets are located on both sides of the shell, which makes air cooling more efficient. The side-by-side arrangement of the battery cells optimizes space utilization.

The reasonable air duct design ensures that the cold air is evenly delivered to the side of each battery cell, while the hot air is smoothly discharged. In addition, the design of the front-end fan speeds up the hot air discharge speed and reduces the battery cell temperature. As the smallest unit of the energy storage battery cluster, this unique design realizes a pneumatic cooling circuit with air inlet on both sides and air outlet at the front end, effectively improving battery performance and life.
