Title:
BATTERY MODULE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/160180
Kind Code:
A1
Abstract:
The present application relates to a battery module, comprising a housing, a first cell layer, a second cell layer, a middle partition plate, and an air supply unit. The first cell layer, the middle partition plate, and the second cell layer are fixedly stacked in sequence in the housing. A main air duct, a first secondary air duct, and a second secondary air duct are disposed in the middle partition plate, the main air duct running through the middle partition plate, and the first secondary air duct and the second secondary air duct respectively being connected between the main air duct and a first side edge and second side edge. A first ventilation hole and a second ventilation hole are disposed on the housing. The air supply unit is fixedly connected to the housing, and the air supply unit is used for discharging the air in the middle partition plate to the outside of the housing via the first ventilation hole. The middle partition plate in the battery module of the present application can implement the heat dissipation effect of air intake on three sides and air discharge on one side, so that the cooling capability for the first cell layer and the second cell layer is stronger, thereby reducing the temperature difference of the battery module and increasing the service life of the battery module. The present application also relates to a vehicle equipped with the battery module.
