Title:
BATTERY CELL MODULE AND ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2022/217980
Kind Code:
A1
Abstract:
Disclosed in the present application are a battery cell module and an electric automobile. The battery cell module comprises a box body, a plurality of side boxes and a plurality of battery cells, wherein the box body is provided with a first mounting face, a second mounting face, a main cooling chamber and a cooling medium outlet; each side box is provided with a side cooling chamber; the side cooling chambers are in bidirectional communication with the main cooling chamber; the side boxes are arranged on the second mounting face; and the bottom face of a square battery cell is attached to the first mounting face, and two opposite side faces thereof both abut against surfaces of the side boxes. A cooling medium enters the side cooling chambers via the main cooling chamber, then returns the main cooling chamber from the side cooling chambers, and finally leaves the box body via the cooling medium outlet. The bottom of the battery cell is attached to the first mounting face, and the two sides thereof abut against side surfaces of the side boxes, so that when the cooling medium flows in the battery cell module, the cooling medium does not come into contact with the battery cell, and the aim of heat dissipation for the square battery cell can be achieved, thus avoiding insulation failure of the battery cell.
