The most effective cooling system to control the operating temperature of the battery pack over the last several years is a liquid cooling battery thermal management system (BTMS). This work has successfully designed and manufactured liquid cooling BTMS-integrated Li-ion battery module with 36 V 20 Ah capacity for electric vehicle applications. The module consists of two stacks of 18 V 20 Ah battery modules arranged by 20 Li-NMC cells in configurations of series-parallel combination. The cooling plates were on each stack side for side transfer through battery poles. The thermal behavior of the module has been monitored in various charging C-rates, i.e., 0.3 C, 0.5 C, and 0.8 C. The experimental result shows that the rise of the C-rate increases the temperature of batteries. The essential operation of the module shows how the overheating thermal problem causes battery malfunction. The module temperature reached over 60°C after 20 minutes which may cause an explosion and deterioration of the capacity. After activating the liquid cooling BTMS at a constant flow rate of 2 lpm, the module can operate safely at a charging C-rate of 0.8 C with a maximum temperature of 55°C. A consistent thermal behavior through a repetitive cycle is also demonstrated. [ABSTRACT FROM AUTHOR] |
