A lithium-ion battery package model was established. The influence of inlet velocity, inlet angle and battery space on the heat dissipation capacity of the lithium-ion battery pack was studied by the method of computational fluid dynamics. The single factor analysis and orthogonal test were used to optimise the lithium-ion battery package. The results showed that the best cooling effect was obtained under the conditions of 15 m/s wind speed, 8° inlet angle and equal battery spacing; the maximum temperature and temperature difference were reduced by 11.81% and 35%, respectively.
