The present disclosure includes a battery module with a housing having first and second ends and first and second lateral sides between the first and second ends. The battery module includes prismatic electrochemical cells and a cooling duct having first and second segments. A first body of the first segment extends along the first lateral side of the housing and includes a first opening to environment. A second body of the second segment extends along the second lateral side of the housing and includes a second opening to the environment. The first and second openings are proximate to the second end of the housing. The battery module includes a fan disposed on the first end of the housing. The fan is fluidly coupled to the cooling duct and provides airflow through the first and second openings and along the first and second bodies.
