Abstract
The utility model discloses a battery pack with parallel tabs. The battery pack comprises batteries stacked along the vertical direction in sequence, wherein a positive electrode tab and a negative electrode tab are respectively arranged on both sides of each battery; the positive electrode tabs between the batteries are staggered diagonally; the negative electrode tabs between the batteries are staggered diagonally; and the negative electrode tabs are connected through a connector. The battery pack provided by the utility model is simple and centrally symmetrical in structure, and the positive electrode tab and the negative electrode tab are respectively arranged on both ends of the battery pack. In addition, the battery pack is convenient and simple to assemble.
Description
Technical field
The utility model relates to field of batteries, particularly a kind of lug parallel-connection type power battery pack.
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.Power battery pack 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, and 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 is 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 parallel-connection type power battery pack.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of lug parallel-connection type power battery pack, comprise that each battery vertically stacks successively, described battery both sides are respectively arranged with positive pole ear and negative lug, stagger at the diagonal angle respectively in positive pole ear position between described each battery, staggering at the diagonal angle respectively in negative lug position between described each battery, connects by connector between wherein said negative lug.
For the manufacturing that makes battery is easier, stagger before and after the position of described battery both sides positive pole ear and negative lug.
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: 1. simple in structure through improvement; Central Symmetry, two goes out lug, negative pole of a positive pole, 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 exploded view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2.A kind of lug parallel-connection type power battery pack, comprise that each battery 1 vertically stacks successively, described battery 1 both sides are respectively arranged with positive pole ear 2 and negative lug 3, stagger at the diagonal angle respectively in positive pole ear 2 positions between described each battery 1, staggering at the diagonal angle respectively in negative lug 3 positions between described each battery 1, connects by connector 4 between wherein said negative lug 3, and its lug position is easy to connect, connected mode is simple, saves material.Battery 1 has enough spaces, guarantees that positive pole ear 2 and negative lug 3 have enough width to bear the battery pack load.
Stagger before and after the position of described battery 1 both sides positive pole ear 2 and negative lug 3, make when assembled battery 1, each positive pole ear 2 and negative lug 3 just in time stagger, and be interference-free during assembling, and wiring is convenient easily, also is convenient to change maintenance.
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.
