Problems solved by technology

[0003] Existing battery modules usually consist of components such as batteries and cooling devices. When cooling the batteries, the existing battery modules usually directly contact the cooling medium with the batteries or electrical components through the cooling device. , thus causing dew condensation inside the cell module, which in turn leads to insulation failure of the cell module

Abstract

The invention discloses a battery cell module and an electric vehicle. The battery cell module comprises a box body, a plurality of side boxes and a plurality of battery cells, the box body is provided with a first mounting surface, a second mounting surface, a main cooling chamber and a cooling medium outlet, the side boxes are provided with side cooling chambers, the side cooling chambers are bidirectionally communicated with the main cooling chamber, the side boxes are arranged on the second mounting surface, the bottom surfaces of the square battery cells are attached to the first mounting surface, and the two opposite side surfaces abut against the surfaces of the side boxes. A cooling medium enters the side cooling chambers through the main cooling chamber, then returns to the main cooling chamber through the side cooling chambers, and finally leaves the box body through the cooling medium outlet. The bottom of the battery cell is attached to the first mounting surface, and the two sides of the battery cell abut against the side surface of the side box, so that when the cooling medium flows in the battery cell module, the cooling medium does not make contact with the battery cell, the purpose of cooling the square battery cell can be achieved, and the insulation failure of the battery cell is avoided.

Description

technical field [0001] The present application relates to the technical field of cell cooling, in particular to a cell module and an electric vehicle. Background technique [0002] With the continuous increase of the number of motor vehicles, while it is convenient for people to travel, the environmental pollution caused by it has also attracted people's attention. At present, all countries in the world are vigorously developing electric vehicles. When the battery core is working, the temperature of the battery core will rise sharply, which will affect the life and safety of the battery core. Therefore, the battery core needs to be cooled. [0003] Existing battery modules usually consist of components such as batteries and cooling devices. When cooling the batteries, the existing battery modules usually directly contact the cooling medium with the batteries or electrical components through the cooling device. , thus causing dew condensation inside the cell module, which in...
