The utility model in order to better understand, below with reference to Fig. 1 to Fig. 8 to the battery pack of the utility model embodiment into
Row detailed description.
Fig. 1 is a kind of structural schematic diagram of battery pack provided by the embodiment of the utility model.
Refering to fig. 1, the utility model embodiment provides a kind of battery pack, comprising: shell 10, it is more than two (contain two
It is a) battery modules 20 and thermal insulator 30.
Shell 10 has accommodation space 11, and more than two battery modules 20 are arranged in accommodation space 11, battery modules 20
It may include a row or two rows or more.Each battery modules 20 include multiple single batteries 21 and are coated on multiple single batteries
The shell 22 of 21 peripheral sides.
Thermal insulator 30 is compressiblly set between two adjacent battery modules 20.
In general, it is arranged side by side and the distance between two adjacent battery modules 20 is 3~5mm, one of electricity
Chi Mo group 20 occur thermal runaway when, temperature can be rapidly increased to 500~600 DEG C it is even higher, thermal runaway directly, will be passed promptly
Adjacent battery modules are delivered to, or melt the shell 22 of adjacent battery modules, lead to the energy in adjacent battery modules 20
Thermal runaway occurs rapidly for amount unit.Thermal insulator 30 can obstruct the energy transmission between two adjacent battery modules 20, delay
The tolerance time of 20 thermal runaway of battery modules diffusion, a possibility that making adjacent battery modules 20 that thermal runaway occur, are preferably minimized.
In addition, internal energy unit can generate certain expansive force in the entire life cycle of battery modules 20,
Under expansive force effect certain deformation occurs for shell 22, when deforming more than certain require, will lead to the weldering of battery modules 20
Destruction on seam cracking or other structures.The compressible characteristic of thermal insulator 30 is conducive to adaptive according to the variation of local environment
It adjusts the installation gap between adjacent battery modules 20 with answering, prevents shell 22 from biggish deformation occurs.
Specifically, depending on size of the thickness of thermal insulator 30 between two adjacent battery modules 20, generally 1
~10mm.When assembled battery packet, a degree of precommpression can be carried out to thermal insulator 30, so that heat occur in battery modules 20
Reduce the size after 30 expanded by heating of thermal insulator when out of control, and then reduce the deformation of shell 22, improves the reliability of battery pack.
Battery pack provided by the embodiment of the utility model, by the way that thermal insulator is arranged between two adjacent battery modules 20
30, the energy transmission between two adjacent battery modules 20 can be obstructed, the tolerance for delaying 20 thermal runaway of battery modules to spread
Time prevents the shell 22 of battery modules 20 from deforming because of thermal runaway expansion.
The specific structure of battery pack provided by the embodiment of the utility model is further described with reference to the accompanying drawing.
Fig. 2 is the structural schematic diagram of the battery modules in battery pack shown in FIG. 1, and Fig. 3 is in battery modules shown in Fig. 2
Single battery structural schematic diagram.
Referring to Figure 2 together and Fig. 3, the shell 22 of battery modules 20 include along spaced two sides first direction X
Plate 221 and two side plates 221 of connection and two top plates 222 being oppositely arranged.Battery modules 20 further include being set to 22 liang of shell
One end in each of the end plate 23 at end, two side plates 221 and two top plates 222 can be fastened to an end plate 23, two side plates
221 and two top plates 222 in each of the other end can be fastened to another end plate 23.
Multiple single batteries 21 are connected with each other by way of series connection and/or parallel connection, and along first direction X and are arranged
It is placed between two side plates 221.Each single battery 21 by battery case 211, the cap assemblies being connect with battery case 211 214,
And it is contained in electrode assembly (not illustrating), electrolyte (not illustrating) and active material between battery case 211 and cap assemblies 214
Material (not illustrating) is fabricated.Cap assemblies 214 include positive electrode terminal, negative electrode terminal, and electrode assembly is electrically connected respectively to just
Electrode terminal and negative electrode terminal.
Specifically, when positive electrode terminal and negative electrode terminal are located at heteropleural, battery case 211 includes surrounding two lid groups
Two first surfaces 212 and two first surfaces 212 of connection that part 214 is arranged and two second surfaces 213 being oppositely arranged；When
When positive electrode terminal and negative electrode terminal are located at ipsilateral, battery case 211 includes the first table around the setting of a cap assemblies 214
Face 212, second surface 213 and the bottom surface (not illustrating) for connecting first surface 212 and second surface, and the first of battery case

Violent electrochemical reaction can occur with electrolyte, a large amount of heat history can be generated in single battery 21, to accelerate monomer
The degeneration of battery 21.
Since the area of the area ratio second surface 213 of first surface 212 is big, along inside corresponding battery case 211
The content distribution of electrolyte and active material on one surface, 212 direction is more, electrochemical reaction is more violent；Therefore in the first table
The heat in face 212 is gathered and heat transmitting is higher relative to second surface 213.Therefore the battery modules 20 contacted with first surface 212
Shell 22 side plate 221 heat it is higher, on the one hand, due to heat transmitting unevenly cause 221 temperature rise of side plate excessively high so that
The whole heat distribution of battery modules 20 is uneven, influences the consistency of battery modules 20；On the other hand, 221 temperature rise of side plate is excessively high
It is easily deformed, leads to the Joint failure between 20 end plate 23 of side plate 221 and battery modules, influence the stabilization of the connection of battery modules 20

Non-metal shell is poor relative to the thermal conduction characteristic of metal shell, leads to the reduction of single battery radiating efficiency, and occur thermal runaway can
Energy property is higher and higher.
For battery modules 20, if thermal runaway has occurred in some single battery 21, the transmission path of heat is successively
It is: the battery case 211 and positive and negative electrode electric connecting sheet of single battery 21.Due to this heat compensator conducting property, as long as in multiple monomer electricity
Setting has the gasket of heat insulating function between the second surface 213 in pond 21 and the top plate 222 of shell 22, can prevent most
Heat transfer, and energy transmission of the single battery 21 to adjacent battery modules 20 of thermal runaway occurs, it is limited to monomer electricity
In the range of the thickness direction in pond 21, so as to cause shell 22 side plate 221 by temperature with higher.For example, aluminium alloy is golden
Belong to the high temperature aluminum that the especially side plate 221 of shell 22 translates into liquid when close to 660 DEG C of fusing point, leads to adjacent battery modules
Thermal runaway occurs rapidly for the energy unit in 20, and side plate 221 will also generate biggish deformation.
Thermal insulator 30 is set to as a result, between the side plate 221 of two adjacent battery modules 20, can be obstructed adjacent
Energy transmission between two battery modules 20, the tolerance time for delaying 20 thermal runaway of battery modules to spread.
