Thermal Management for Battery Module with Liquid-Cooled Shell Structure under High Charge/Discharge Rates and Thermal Runaway Conditions

In this paper, the thermal management of a battery module with novel liquid-cooled shell structure is investigated under high charge/discharge rates and runaway conditions. The consists 4 × 5 cylindrical batteries embedded in aluminum multiple flow channels. suppression propagation were experimentally examined. temperature rise discharging process significantly greater than that charging phase. As coolant speed increases, maximum decreases slightly, while difference remains at same level, expense much-increased pressure drop. With presented shell, was for both internal corner runaway. It found adjacent can be maintained 70 °C, indicating successfully suppressed by heat dissipation through surrounding liquid flow. addition, electrically induced profile along interconnection identified imaging. Hot spots on confluence busbars series connection. order to improve safety modules, parallel connection recommended, which reduce busbar 4.86 as determined numerical simulations. Experimental measurements also conducted verify simulation results.
