The Lithium-ion (Li-ion) battery has widely applied to electric vehicles and hybrid electric vehicles because of its performance such as high energy density and low self-discharging rate. However, thermal runaway such as fire and explosions can be triggered by thermal abuse operation of Li-ion battery. To relieve this situation, efficient battery cooling system is essential for battery thermal management. We investigate the optimization of mini-channel geometry, coolant flow rate and coolant temperature in liquid cooling system of the Li-ion battery module. Case studies utilizing computational fluid dynamics (CFD) are carried out and each variables is optimized using artificial neural network model (ANN). Nail penetration is employed to estimate thermal management of the proposed liquid cooling system. The temperature distribution, the maximum temperature and thermal runaway propagation are analysed and the results are compared with the other mini-channel cooling systems.
