(as shown in Figure 2).As shown in figure 3, battery modules 1 provided by the embodiments of the present application include above-mentioned multiple battery units 11 and converge
Flow bar assembly 12.It is understood that multiple battery units 11 refer to that there are two the battery units 11 of above (including two).
In the embodiment of the present application, battery modules 1 can be the battery modules of the battery modules of horizontal lying-type or formula of lying on one's side, in vertical direction
On, multiple battery units 11 include upper layer battery unit and lower layer's battery unit.The embodiment of the present application is with horizontal lying-type battery modules
For be illustrated, it will be appreciated by those skilled in the art that the invention relates to busbar assembly 12
Can be used for lying on one's side formula battery modules.After vertical direction in the embodiment of the present application refers to that battery modules are installed, place
In on level ground, the perpendicular direction with level ground.
As shown in Figure 1, busbar assembly 12 includes upper layer busbar 121, lower layer's busbar 122 and insulating component 123.Such as
Shown in Fig. 3, upper layer busbar 121 is used to be attached at the electrode terminal 112 of the two neighboring battery unit 11 in upper layer, so that upper layer
Two neighboring battery unit 11 realizes series connection.Lower layer's busbar 122 is used to be attached at the electricity of the two neighboring battery unit 11 of lower layer
On extreme son 112, so that the two neighboring battery unit 11 of lower layer realizes series connection.By multiple busbar assemblies, thus by multiple
Battery unit 11 is connected.It is connected between upper layer busbar 121 and lower layer's busbar 122 by insulating component 123.
The insulating component 123 can also lead to 122 integrated injection molding of upper layer busbar 121 and lower layer's busbar
Other modes are crossed to form.Preferably, insulating component 123 is infused with upper layer busbar 121 and 122 one of lower layer's busbar respectively
It is moulded into type.
In process of production, as shown in Figures 2 and 3, in addition to both ends battery unit 11 near outside electrode terminal
Except 112, for being located at the electrode terminal 112 of middle section, busbar assembly 12 is installed, in the correspondence of upper layer busbar 121
On the electrode terminal 112 (one end positive terminal and one end negative terminal) of the two neighboring battery unit 11 of layer, lower layer's busbar 122
On the electrode terminal 112 of the corresponding two neighboring battery unit 11 of lower layer (one end positive terminal and one end negative terminal).Due to exhausted
The isolation of edge component 123 avoids and short circuit occurs between upper layer busbar 121 and lower layer's busbar 122, and then avoids generation
Safety accident.
Referring to Fig.1, as an example, insulating component 123 includes main part 123c, and main part 123c is located at upper layer remittance
It flows between item 121 and lower layer's busbar 122, upper layer busbar 121 and lower layer's busbar 122 is isolated.
Due to the cold and hot variation of temperature, a certain amount of condensed water is generated sometimes on battery unit 11, condense when generating
When water, it is easy to be connected between upper layer busbar 121 and lower layer's busbar 122.In order to avoid the generation of the problem, preferably
It is that diversion trench 123d, the separate battery unit 11 of main part 123c are provided on the aforementioned body portion 123c of insulating component 123
A side surface protrude from upper layer busbar 121 separate battery unit 11 a side surface, the close upper layer of main part 123c
One end of busbar 121 is provided with above-mentioned diversion trench 123d, and diversion trench 123d has inclined guide face 123e.In this way, water conservancy diversion
Slot 123d can just accept the condensed water flowed down on upper layer busbar 121, and condensed water can be flowed down along guide face 123e,
Without flowing on lower layer's busbar 122.
Preferably, as shown in Figure 1, guide face 123e is along the separate central axes of busbar assembly 12 in the vertical direction
Direction tilts down.That is, being directed toward on the inside of busbar assembly 12 on the direction in 12 outside of busbar assembly, guide face
123e is tilted down, and in this way can not only be drained condensed water to the side of lower layer's busbar 122, moreover it is possible to by busbar assembly 12
Inside To Outside drainage, further avoids condensing drip and falls on lower layer's busbar 122.
It is two it is possible to further which the quantity of diversion trench 123d is arranged, two diversion trench 123d axial symmetry settings, and
The central axes of busbar assembly 12 in the vertical direction are symmetry axis.In this way, the condensed water on upper layer busbar 121 can
The two sides for flowing to busbar assembly 12 respectively along two diversion trench 123d, without flowing on lower layer's busbar 122.It converges on upper layer
The guide face 123e that condensed water on stream item 121 is tilted down along two flows down, and avoids condensation flow and converges to lower layer
Cause the short circuit of upper layer busbar 121 and lower layer's busbar 122 on item 122.
As shown in Figure 1, above-mentioned insulating component 123 can also include upper limit portion 123a and lower limit portion 123b, upper limit
Portion 123a clamps upper layer busbar 121, and lower limit portion 123b clamps lower layer's busbar 122, and aforementioned body portion 123c is located at upper layer
Between busbar 121 and lower layer's busbar 122.Upper limit portion 123a and lower limit portion 123b may each be strip, molding
Or processing is all more convenient.By the way that upper limit portion 123a and lower limit portion 123b is arranged, it can prevent upper layer busbar 121 under
Layer busbar 122 is fallen off with insulating component 123, makes upper layer busbar 121 and lower layer's busbar and 122 and insulating component
123 connection is more stable.
Further, the material of insulating component 123 is plastic cement, above-mentioned limiting section 123a, lower limit portion 123b, main part
123c, diversion trench 123d and the direct single injection-molded of guide face 123e are not necessarily to secondary operation, time saving and energy saving.
