Embodiment Construction

[0020] figure 1 An embodiment of an assembled battery assembly 100 is shown, which includes a plurality of cells 120 , a plurality of cell positioning components 130 , a cooling plate component 140 and a heat conducting film 110 . Wherein, the heat conduction film 110 is shuttled and arranged between the electric core 120 and the electric core positioning part 130 in the form of reciprocating folding, and finally connected to the cooling plate part 140 . During the working process, the heat absorbed from the battery cell 120 passes through the entire heat conduction film 110 or a partial section of the heat conduction film 110 and is conducted to the cooling plate member 140 to dissipate heat, thereby cooling the battery cell 120 . The battery assembly 100 of this embodiment only uses the heat conduction film 110 to complete the entire heat dissipation process. While achieving a good cooling effect on the battery cells, it does not need to occupy too much space for the heat di...

Abstract

The invention provides a battery module. The battery module comprises a plurality of cells for providing electric energy, a plurality of cell positioning parts for positioning and installing the cells, cooling plate parts for providing cold energy as well as a heat conducting film, wherein the heat conducting film comprises a plurality of heat absorption zones and a plurality of transition zones, each heat absorption zone makes contact with at least one surface of the corresponding cell and absorbs heat from the cell, and the transition zones are connected between the heat absorption zones respectively; heat of the heat conducting film is conducted to the cooling plate parts. According to the battery module, one heat conducting film is arranged between the plurality of cells and the heat absorption zones are connected in series by means of the transition zones of the heat conducting film, so that the heat absorbed by the whole heat conducting film is conducted to the cooling plate parts, the cells are well cooled, too large cooling structure arranging space is not needed, and the overall occupation space of the battery module can be saved.

Description

technical field [0001] The invention relates to the field of electric vehicles, and more specifically, the invention relates to a vehicle battery assembly with good heat dissipation and small space occupation. Background technique [0002] In the current field of new energy electric vehicles, the cooling methods of its power battery components mainly include: natural cooling, air cooling and liquid cooling. Among them, the liquid cooling method usually adopts the cooling of the surface of each battery cell and the cooling based on one surface of the module. The liquid cooling method for the surface of each battery cell has relatively the best heat dissipation effect, but it also has correspondingly higher costs and poor space utilization, which leads to relatively poor reliability. Based on the heat dissipation method adopted on the bottom surface of the module or one of the surfaces, it is technically easier to implement, but the heat dissipation effect will be relatively ...
