Description
[technical field]
The utility model belongs to lithium battery pack structure-design technique field, has overcurrent fuse protection more particularly to one kind
The lithium battery pack structure of function.
[background technique]
With gradually popularizing for new-energy automobile, the demand of dynamic lithium battery also gradually increases.In new-energy automobile, move
Power power module can be integrated by multiple dynamic lithium batteries and form a dynamic lithium battery packet.Power lithium in the prior art
The connection sheet structural formula of battery pack is made of the row's connection of multiple lithium battery assembly connections, and the connecting pin of each lithium battery is jointly with one
Connection sheet connects to form electrically conducting, gradually can be to lithium battery pack when performance issue occurs in lithium battery single in lithium battery pack
Other interior lithium batteries have an impact, to cause power battery security risk and scrap, directly affect dynamic lithium battery entirety
Performance and the service life.
Therefore, it is necessary to provide the new lithium battery pack structure with overcurrent fuse protection function of one kind to solve above-mentioned ask
Topic.
[utility model content]
The main purpose of the utility model is to provide a kind of lithium battery pack structure with overcurrent fuse protection function,
Solving single lithium battery in dynamic lithium battery packet and will affect other lithium battery performances after going wrong causes service life short
Problem.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of lithium electricity with overcurrent fuse protection function
Pond pack arrangement comprising aluminum hull box body, setting are in the intracorporal several lithium batteries of the aluminum hull box, closing aluminum hull box body top
Cover board and connection row, be provided with several electric connecting points being extremely connected to the lithium battery on the cover board, it is described
Connection row includes corresponding the connection branch tablet being connected to the electric connecting point and connecting all connection branch tablets
Integral connection total tablet is provided with overcurrent fusing structure on each connection branch tablet.
Further, the overcurrent fusing structure include be arranged in it is described connection branch tablet on and will connection branch tablet every
The port opened, the fuse for being horizontally through the port.
Further, the overcurrent fusing structure further includes that the port is wrapped up closed clad.
Further, the clad is isolation material.
Further, the overcurrent fusing structure includes being embedded the insulation on the connection branch tablet and blocked
Piece, be arranged in the insulating trip and connection it is described connection branch tablet through-hole and be arranged in the through-hole by the company
Connect the fuse of branch tablet conducting.
Compared with prior art, a kind of lithium battery pack structure with overcurrent fuse protection function of the utility model is beneficial
Effect is: by the way that several connection branch tablets, and setting control and lithium on connection branch tablet are arranged on original connection row
Overcurrent fuse protection structure battery electrode end conducting or blocked, when performance fault occurs for single lithium battery, overcurrent fusing knot
Fuse in structure fuses because electric current is excessive, so that electrically conducting of the fail battery with the row of connection has been blocked, so that
Single lithium battery, which breaks down, will not influence the performance of other lithium batteries in battery pack after performance issue, to substantially increase
The stability of lithium battery pack entirety, improves security performance and service life.

[specific embodiment]
Embodiment:
Fig. 1-Fig. 2 is please referred to, the present embodiment is the lithium battery pack structure 100 with overcurrent fuse protection function comprising
Aluminum hull box body 1, several lithium batteries (not identified in figure) being arranged in aluminum hull box body 1, the cover board 2 for closing 1 top of aluminum hull box body
And connection arranges 3, is provided with several electric connecting points (not identifying in figure) being extremely connected to the lithium battery on cover board 2,
Connection row 3 includes corresponding the connection branch tablet 31 being connected to the electric connecting point and connecting all connection branch tablets 31
Integral connection total tablet 32 is provided with overcurrent fusing structure on each connection branch tablet 31.
Referring to figure 3., in one embodiment, the overcurrent fusing structure includes being arranged on connection branch tablet 31 and inciting somebody to action
Connection branch tablet 31 separate port 33, be horizontally through the fuse 34 of port 33 and 33 both sides of port linked together and wrapped
The clad 35 wrapped, the clad 35 are made by isolation material.
Referring to figure 4., in another embodiment, the overcurrent fusing structure includes being embedded on connection branch tablet 31 and inciting somebody to action
Its block insulating trip 36, be arranged in insulating trip 36 and connection connection branch tablet 31 through-hole 37 and be arranged in through-hole 37
The interior fuse 38 that connection branch tablet 31 is connected.
The present embodiment has the lithium battery pack structure 100 of overcurrent fuse protection function by being arranged on original connection row
Several connection branch tablets, and the overcurrent fuse protection that setting control is extremely connected or blocks with lithium battery on connection branch tablet
Structure, when performance fault occurs for single lithium battery, the fuse in overcurrent fusing structure fuses because electric current is excessive, from
