Abstract
The utility model discloses a battery pack with tabs in parallel connection at the middle part. The battery pack comprises a battery module including a plurality of batteries sequentially stacked along the vertical direction, wherein a positive electrode tab and a negative electrode tab are respectively arranged on both sides of each battery; the positive electrode tabs are all arranged on the right side of the battery module; the negative electrode tabs are all arranged on the front side of the battery module; the positive electrode tabs of the battery module are arranged front and back in a staggered manner; and the negative electrode tabs of the battery module are arranged on the same vertical line at the middle part. The battery pack provided by the utility model has the advantages of simple structure, and central symmetry; and the tabs are led out from both ends to serve as a negative electrode connection end and a positive electrode output end, respectively. In addition, the battery pack is convenient and simple to assemble.
Description
Technical field
The utility model relates to field of batteries, particularly parallel-connection type power battery pack in the middle of a kind of lug.
Background technology
Along with becoming increasingly conspicuous of environmental problem, low-carbon economy has become the main flow of economic development.Hybrid vehicle and electric automobile have also obtained vast production firm and consumer's approval gradually as the representative of new-energy automobile.The power battery pack group as the main power source of new-energy automobile, is one of critical component of electric automobile.
Characteristics and the application scenario of power battery pack itself are more special, and the user is very strict to the requirement of the aspects such as its capacity, multiplying power, reliability and fail safe.At present, electrokinetic cell or the lithium ion series battery of volume production can be accepted, be fit to high power capacity and good rate capability, cost, as LiFePO4, lithium titanate, nickle cobalt lithium manganate etc.But, in the high-multiplying-power battery field; Battery pole ear can not have good performance when large electric current, when the high temperature that is easy to fuse, production electrokinetic cell, difficulty is large, assembling is difficult, cost is high.In fact expensive, the high price of battery pack and the inefficient bottleneck that becomes the battery pack development, prior art be mostly for the cycle performance of power cell, goes out lug scheme technology seldom for the battery of power battery pack packaging technology.In view of this, necessaryly provide a kind of power battery pack packaging technology with superperformance, high efficiency, low price to adapt to current demand.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lug middle parallel-connection type power battery pack.
The technical scheme that its technical problem that solves the utility model adopts is:
Parallel-connection type power battery pack in the middle of a kind of lug, comprise that each battery vertically stacks into battery modules successively, described battery both sides are respectively arranged with positive pole ear and negative lug, wherein said positive pole ear is positioned at the right side of battery modules, described negative lug is positioned at the left side of battery modules, each positive pole ear of described battery modules is and is staggered front to back arrangement, in the middle of each negative lug of described battery modules is arranged on same vertical line.
In order to guarantee the stable connection of each negative lug, each negative lug of described battery modules connects by connector.
As a preference, the width of described positive pole ear and negative lug is 5～50mm, and thickness is 0.1～3mm.
The beneficial effects of the utility model are: the structure of this power battery pack has the following advantages through improvement: 1. and simple in structure, Central Symmetry, two goes out lug, and a side is as the negative pole link, and a side is as cathode output end, this structure can be more convenient when power battery assembling, and assembling is simple; 2. technique is simple, is easy to realize volume production, meets production requirement according to the existing line that produces, and does not need extra input; 3. form power battery pack satisfactory for result, because lug has sufficient space easy to connect, can directly use riveted joint, welding, effect is good; 4. cost is low, and the scope of application is wide, is the effective scheme that enters the power battery pack packaging technology, and has effectively solved existing battery bottleneck.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is front view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2.parallel-connection type power battery pack in the middle of a kind of lug, comprise that each battery 11 vertically stacks into battery modules 1 successively, described battery 11 both sides are respectively arranged with positive pole ear 2 and negative lug 3, wherein said positive pole ear 2 is positioned at the right side of battery modules 1, described negative lug 3 is positioned at the left side of battery modules 1, each positive pole ear 2 of described battery modules 1 is and is staggered front to back arrangement, each negative lug 3 of described battery modules 1 is arranged on middle same vertical line, its lug position especially is easy to connect as the negative lug 3 of link, interference-free during assembling, wiring is convenient easily, also be convenient to change maintenance.Battery 11 has enough spaces, guarantees that positive pole ear 2 and negative lug 3 have enough width to bear the battery pack load.Each negative lug 3 of battery modules 1 can directly connect, and also connects by connector 4, couples together more firm by connector 4 by contrast.
As a preference, the width of described positive pole ear 2 and negative lug 3 is 5～50mm, and thickness is 0.1～3mm, and too little meeting affect the battery pack load, too greatly can cause waste.
Can find out in conjunction with top description, with respect to prior art, the utility model power battery pack has the following advantages: structure and technique are simple, be easy to realize volume production, cost is low, and the scope of application is wide, be suitable in power battery pack, but large-scale popularization on monomer battery structure and packaging technology particularly.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.Except using this technology, also can use this technology in the energy-storage battery pack module in power battery pack module.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
