Abstract
The utility model discloses a series connection structure of a battery pack and relates to a battery. The series connection structure comprises a plurality of battery bodies, wherein a positive battery pole tab and a negative battery pole tab led out of each battery body are arranged on each battery body. The series connection structure is characterized in that the battery pole tabs, with the same polarity, of every two adjacent battery bodies are bent by 90 degrees; pole tab buffer zones are arranged; and the adjacent battery pole tabs bent by 90 degrees are connected together by the pole tab buffer zones. The pole tab buffer zones are copper-aluminum connecting pieces. The connecting structure is stable, reliable, and low in resistance, the power supply stability of the battery can be improved, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of battery, particularly a kind of syndeton of lithium battery battery group.
Background technology
Battery pack is a plurality of unit cells series connection of a kind of a plurality of lithium battery, lead-acid battery or other types or a kind of electric supply installation be connected in parallel.A unit cells comprises cell body, and cell body inside is chemical substance, produces electron ion by various chemistry reflections, by be drawn out to generation current outside positive and negative battery pole ear in cell body.
General series connected battery group, refer to the structure that the both positive and negative polarity electrode of battery connects successively.Existing connect in series structure, be all by screw, lug to be fixed on copper bar, if couple corrosion has occurred, the lug of battery all damages, the battery maintenance inconvenience, and need to change the lug of all and the battery that connects together.
Because, when copper, aluminium conductor directly connect, the contact-making surface of these two kinds of metals very easily forms electrolyte under the effect of moisture in air, carbon dioxide and other impurity, thereby form take aluminium as negative pole, copper be anodal primary cell, be that aluminium produces couple corrosion, cause the contact resistance of copper, aluminium junction to increase.In addition, because modulus of elasticity and the thermal coefficient of expansion of copper, aluminium differs greatly, be in operation after cold cycling (energising and outage) repeatedly, can make the contact point place produce larger gap and affect contact, also increased contact resistance.The increase of contact resistance, in servicely will cause that temperature raises.Under high temperature, corrosion oxidation will aggravate, and produces vicious circle, and quality of connection is further worsened, the accident such as finally cause that the contact point excess Temperature even can smolder, burn.
The utility model content
The purpose of this utility model is a kind of battery pack structure be connected in series of invention, makes interconnecting of each unit cells reliable and stable.
The utility model comprises a plurality of cell bodies, each cell body is provided with the positive and negative battery pole ear of drawing from cell body inside, it is characterized in that: battery pole ear bending 90 degree of the same polarity of adjacent two cell bodies, and being provided with the lug buffer strip, described lug buffer strip links together the battery pole ear of adjacent bending 90 degree.
Described lug buffer strip is copper aluminium brace.
The disclosed this battery pack syndeton of the utility model, be the battery pack structure that a kind of same polarity electrode is connected mutually, utilizes the lug buffer strip will need the battery pole ear of series connection to be fixed together.This stable connection is reliable, and resistance is low, can improve battery for electrical stability, increase the service life.
The accompanying drawing explanation
Fig. 1, structure chart of the present utility model.
Fig. 2, the plan view of Fig. 1.
Embodiment
As Fig. 1 and Fig. 2, this is three battery pack structures that battery is in series, and has three cell bodies 1, has the positive and negative electrode battery pole ear 2 of drawing from cell body inside on each cell body.For easy to connect, three cell bodies are equidirectional side by side, and the battery pole ear that polarity is identical is positioned at homonymy.The battery pole ear of the same polarity of adjacent two cell bodies bends 90 degree to the inside, form " the lug face " that there be gap in a centre, below at this " lug face ", be provided with lug buffer strip 3, and lug buffer strip 3 is connected with above-mentioned two adjacent, battery pole ears 2 that bend 90 degree.Described lug buffer strip 3 is copper aluminium braces, and battery pole ear adopts ultrasonic bonding.The ultrasonic wave metal welding is to utilize the dither ripple to be delivered to the metal surface of two need welding, in the situation that pressurization, make two metal surface phase mutual friction and form the fusion between molecular layer, that its advantage is is quick, energy-conservation, fusion intensity is high, good conductivity, no-spark, approach cool grinding.
Use the battery pack of the utility model structure, the lug stable connection of each cell body, firmly not only, and also the junction conductance is high, is not easy the situation of striking sparks, opening circuit, and can increase substantially the performance of whole battery pack.
Claims (2)
1. a battery pack connect in series structure, comprise a plurality of cell bodies (1), each cell body is provided with the positive and negative battery pole ear (2) of drawing from cell body inside, it is characterized in that: battery pole ear bending 90 degree of the same polarity of adjacent two cell bodies, and being provided with lug buffer strip (3), described lug buffer strip links together the battery pole ear (2) of adjacent bending 90 degree.
2. battery pack connect in series structure according to claim 1, it is characterized in that: described lug buffer strip (3) is copper aluminium brace.
