Abstract
This application relates to a battery module, including a case, a first electrochemical cell layer, a second electrochemical cell layer, a middle separator, and an air supply unit. A main air duct, a first secondary air duct, and a second secondary air duct are disposed in the middle separator. The main air duct penetrates the middle separator. A first ventilation hole and a second ventilation hole are disposed on the case. In this application, by using the middle separator in the battery module, heat dissipation effect of air intake on three sides and air exhaust on one side may be implemented, and a cooling capability for the first electrochemical cell layer and the second electrochemical cell layer may be improved, thereby reducing a temperature difference of the battery module, and improving a service life of the battery module. This application further relates to a transportation means equipped with the battery module.
