The battery cells 11 are arranged at least two, at least two battery cells 11 are arranged in parallel along the width direction of the module body 1, and a heat insulation plate 13 is clamped between every two adjacent battery cells 11. The battery cell 11 includes a battery cell body 111 and tabs 112, and the separator plate 13 extends out of the battery cell body 111 and at least covers a part of the tabs 112. In addition, referring to fig. 2, the width direction of the module body 1 is the X direction, the length direction of the module body 1 is the Y direction, and the height direction of the module body 1 is the Z direction.
In the case of thermal runaway of the cell 11, the cell 11 may expand and emit high-temperature gas or flame. In this embodiment, be provided with heat insulating board 13 between two adjacent electric cores 11, insulate against heat through heat insulating board 13, when certain electric core 11 thermal runaway in the battery module, can prevent that high temperature gas or flame from contacting with adjacent electric core 11 under the heat insulating board 13 separation. It can be understood that, when the thermal runaway occurs in the battery cell 11, the entire battery cell body 111 and the tab 112 connected to the battery cell body 111 both have higher temperatures, and under the action of thermal radiation, the end face of the battery cell body 111 provided with the tab 112, the end face of the battery cell body 111 opposite to the tab 112, and the tab 112 all radiate heat to the adjacent battery cell 11. Extend electric core body 111 with heat insulating board 13 outside and shelter from partial utmost point ear 112, through the region that increase heat insulating board 13 covered electric core 11, reduce the heat of thermal runaway's electric core 11 to adjacent electric core radiation, protect remaining electric core 11, delayed thermal diffusion effectively, improved the security of battery module.
The heat insulation board 13 is made of aerogel or mica and other materials with low heat conductivity coefficient. Specifically, the thickness of the heat insulation plate 13 is 0.5-3 mm. The thickness of the heat insulating board 13 is preferably set to 1.5 mm.
In order to enhance the effect of delaying the heat diffusion of the battery module, in this embodiment, an elastic member 12 is disposed between the thermal insulation board 13 and the cell body 111, and the size of the elastic member 12 is smaller than that of the thermal insulation board 13. Because have elastic component 12 between heat insulating board 13 and electric core body 111, have the clearance between electric core body 111 and heat insulating board 13, most high temperature gas passes through from this clearance when electric core 11 takes place the thermal runaway to when electric core 11 thermal runaway takes place the inflation, can extrude elastic component 12 and make elastic component 12 produce elastic deformation, can provide sufficient pressure release space for electric core 11.
In an embodiment, the elastic member 12 is clamped between the cell body 111 and the heat insulation board 13, the elastic member 12 is extruded and deformed by the cell body 111 and the heat insulation board 13 by using the elasticity of the elastic member 12, and the elastic member 12 is clamped between the cell body 111 and the heat insulation board 13 to position the elastic member 12.
In another embodiment, the elastic member 12 is bonded to the heat insulating plate 13. Fix elastic component 12 to heat insulating board 13 through the mode that bonds, when the battery module uses under the vibration environment, can prevent that elastic component 12 from droing between electric core body 111 and heat insulating board 13, improve the vibration resistance of battery module. In addition, during actual production, the elastic part 12 can be bonded firstly, and then the heat insulation plate 13 and the elastic part 12 are integrally assembled with the battery cell 11, so that the efficiency of battery module production is accelerated.
Specifically, the elastic member 12 is bonded to the insulation board 13 by a double-sided tape or an adhesive.
Preferably, the elastic member 12 is bonded to the heat insulating plate 13 by a heat insulating paste. The gaps between the elastic pieces 12 and the heat insulation plates 13 are sealed by the heat insulation glue, so that the heat diffusion is favorably delayed. Of course, in other embodiments, other types of adhesives may be used, and the type of adhesive is not particularly limited.
Furthermore, a positioning groove is concavely arranged on one side of the heat insulation plate 13, which is opposite to the battery cell 11, and the elastic part 12 is bonded in the positioning groove through adhesive. The positioning groove is arranged on the heat insulation board 13, so that the installation position of the elastic element 12 can be quickly found, and a space for containing the adhesive can be provided inside the positioning groove, so that the adhesive is prevented from leaking on the outer surface of the heat insulation board 13.
At least two elastic pieces 12 are arranged between the cell body 111 and the thermal insulation board 13, the at least two elastic pieces 12 are distributed at intervals along the length direction of the module body 1, and a heat dissipation channel is formed between the two adjacent elastic pieces 12. The elastic pieces 12 arranged at least two intervals can keep the stress balance of the battery cell body 111, and the battery cell body 111 is prevented from being inclined due to uneven stress. In addition, a heat dissipation channel between the two elastic members 12 reserves a heat dissipation and pressure release channel for the battery cell 11 in thermal runaway.
In order to increase the width of the heat dissipation channel, two elastic members 12 may be disposed between the cell body 111 and the heat insulation plate 13 in actual design.
In this embodiment, referring to fig. 2, the opposite two sides of the cell body 111 are respectively provided with tabs 112 with opposite polarities, the tabs 112 of the adjacent cell bodies 111 are connected by a bus bar (not shown in the figure), so as to realize series connection or parallel connection of the adjacent cell bodies 111, and the two elastic members 12 are disposed near the corresponding tabs 112. The present embodiment is mainly designed for a battery module in which the tabs 112 are respectively led out from two opposite sides of the module body 1, and certainly, in other embodiments, the tabs 112 may be led out from only one end of the cell body 111.
The preferred soft-package battery cell that sets up heat insulating board 13 between two adjacent soft-package battery cells of electric core, extend electric core body 111 with heat insulating board 13 outside and shelter from partial utmost point ear 112 at least, reducible soft-package battery cell spun high-temperature gas or flame when thermal runaway to the influence of the soft-package battery cell 11 of both sides. The heat insulation plate 13 preferably extends outside the cell body 111 and covers at least all of the tabs 112.
Of course, in other implementations, the number of the elastic members 12 between the cell body 111 and the thermal insulation board 13 may be flexibly set according to actual needs.
Preferably, the height of the elastic member 12 is smaller than that of the heat insulating plate 13. The height that sets up elastic component 12 is less than the height of heat insulating board 13, and the position accessible part high temperature gas of the tip that is close to elastic component 12 between electric core body 111 and the heat insulating board improves the radiating effect of postponing.
Specifically, the elastic member 12 is made of a silicone foam material. The elastic member 12 made of the silica gel foam material has the characteristics of light weight, elasticity and low heat conductivity coefficient, and reduces the possibility that the electric core 11 is radiated by the elastic member 12 at a high temperature without thermal runaway to other electric cores 11. Further, the heat-insulating elastic part 12 is located at a position, close to the tab 112, of the cell body 111, and by the design, the influence of radiation heat of the cell 11 on two sides when the cell 11 is in thermal runaway can be reduced under the condition that a pressure relief channel of the cell 11 is not influenced, so that thermal diffusion is effectively delayed.
In one embodiment, the end of the thermal insulation board 13 in the length direction of the module body 1 is flush with the end of the tab 112 away from the cell body 111. The end of the heat insulation plate 13 in the height direction of the module body 1 is flush with the end of the tab 112 away from the cell body 111. This design prevents 11 thermal runaway's of electricity core high temperature gas or flame direct and adjacent 11 contacts of electricity core on the basis that occupies battery module space as far as possible.
In another embodiment, the thermal insulation board 13 protrudes from the end of the tab 112 away from the cell body 111 at the end of the module body 1 in the length direction. The end of the thermal insulation board 13 in the height direction of the module body 1 protrudes out of the side of the battery cell body 111 in the height direction of the module body 1. The thermal radiation of the thermal runaway of the battery cell 11 is weakened by increasing the length of the thermal insulation board 13 protruding from the tab 112 or the battery cell body 111.
In order to further enhance the effect of delaying thermal diffusion, referring to fig. 3, at least two heat dissipation grooves 121 are concavely disposed on one side surface of the elastic member 12, which is attached to the battery cell body 111, the at least two heat dissipation grooves 121 are distributed along the height of the elastic member 12 at intervals, the length of each heat dissipation groove 121 extends from one side back to the heat dissipation channel toward the direction of the heat dissipation channel, and two ends of the heat dissipation groove 121 in the length direction are respectively provided with a heat dissipation port. The two ends of the heat dissipation groove 121 in the length direction are respectively provided with a heat dissipation port, so that one side of the elastic member 12 departing from the heat dissipation channel is communicated with the heat dissipation channel through the heat dissipation groove 121. When the battery cell 11 is out of control thermally, the high-temperature gas released from the battery cell body 111 can flow to the outside from the heat dissipation ports at the two ends of the heat dissipation channel and the heat dissipation grooves 121, so as to provide more pressure relief spaces and guide the high-temperature gas to be released from multiple places as much as possible for the battery cell body 111. In addition, because the at least two heat dissipation grooves 121 are in heat distribution at intervals in the height direction of the elastic member 12, the structural strength and the characteristic of elastic deformation of the elastic member 12 are ensured, and the normal use of the elastic member 12 is not influenced.
Referring to fig. 1 and fig. 2, the battery module that can delay thermal diffusion still includes module casing 2, module casing 2's inside is provided with standing groove 23 that is used for placing module body 1, module casing 2 includes bottom plate 22 and two curb plates 21 that set up relatively, two curb plates 21 set up on bottom plate 22, module body 1 is located between two curb plates 21, be provided with elastic component 12 between module body 1 and the curb plate 21, take place the whole size of inflation increase battery module at certain electric core 11 thermal runaway, this in-process can extrude elastic component 12 between first lateral wall and electric core 11, through elastic component 12 deformation for electric core 11 reserve sufficient pressure release space.
