Title:
BATTERY MODULE, TRACTION BATTERY PACK AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2018/040902
Kind Code:
A1
Abstract:
Disclosed are a battery module (100), a traction battery pack and an automobile. The battery module (100) comprises a plurality of intermediate partition plates (1) stacked in the left to right direction of the battery module (100), a plurality of individual cells (2), a mounting plate (3) arranged on the front side of the battery module (100) and a fan fixed on the mounting plate (3). An intermediate heat-dissipation air plate (5) is arranged on the intermediate partition plates (1). An intermediate heat-dissipation air channel (51) penetrating in the front to rear direction is formed inside the intermediate heat-dissipation air plate (5). A left side face of the intermediate air heat-dissipation plate (5) exchanges heat on the left with right side faces of the individual cells (2), and a right side face of the intermediate air heat-dissipation plate (5) exchanges heat on the right with left side faces of the individual cells (2). The intermediate air heat-dissipation channel (51) is provided with a first air port (511) and a second air port (512). A chamber (6) is provided between the mounting plate (3) and front end faces of the individual cells (2). The first air port (511) is in communication with the chamber (6), and the second air port (512) is arranged in the rear of the battery module (100) and is in communication with the outside of the battery module (100). The battery module (100) has a high heat-dissipation efficiency, and can solve the heat dissipation problem during quick charge and discharge (charging/discharging at a high rate ranging from 3C to 6C).
