Abstract
The utility model relates to a high-capacity lithium ion power battery pole, which comprises a positive pole and a negative pole, and is characterized in that the pole is formed into a whole through acylinder body and an assembling platform with T-shaped cross section, the positive pole and the negative pole adopt a cylinder integrally formed through vertical superposition, and internal threads are formed in the center of the pole. The high-capacity lithium ion power battery pole has the beneficial effects that the pole can be flexibly dismounted at the same time of exerting the double functions of positioning and protection; the pole can minimize the occurrence of poor wire contact, effectively improve the properties, prolong the service life of the battery and ensure the safety of the battery; the assembly process and the procedure can be simplified, the production cost and the product cost are reduced, and the quality of assembled product is enhanced, and the pole is suitable for large-scale industrial production.
Description
Technical field
The utility model belongs to lithium ion battery, relates in particular to a kind of high-capacity lithium-ion power battery pole.
Background technology
Along with the maturation of electric vehicle engineering and perfect day by day, the quality of the vehicle-mounted great-capacity power battery performance that electric automobile, hybrid vehicle use directly affects the overall performance of electric automobile.To electric automobile vehicle mounted dynamic battery have higher requirement (such as will having higher fail safe, more outstanding performance, weight is lighter).The reliability of battery, fail safe also be technological difficulties in the great-capacity power battery manufacturing process and emphasis, particularly battery pole and connector to contact and cooperate all be the important step that directly influences battery performance.The now big vehicle-mounted dynamic lithium battery positive and negative terminals of capacity be connected connector and generally adopt single nut to be flexible coupling, connected mode with the fastening battery lead of screw causes the resistance instability easily, reliability is low, the normal phase is used problems such as can influencing the decay of battery performance life-span, finally causes battery can't continue to use.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology; and provide a kind of high-capacity lithium-ion power battery pole; can assemble up lithium battery pole and assembled conductor with the screw thread cooperation; guarantee in production, use, test process, both to have played to connect and support; play the reliably protecting effect again; make battery in use reduce the internal resistance of cell, improve battery performance.Reduce unnecessary production waste in man-hour, enhance productivity.
The utility model for achieving the above object, by the following technical solutions: a kind of high-capacity lithium-ion power battery pole, comprise positive and negative pole, it is characterized in that: described pole is formed whole by the mounting plate that cylinder and cross section are " T " font, described positive and negative pole is for being superimposed as whole cylinder up and down, and the pole center is provided with internal thread.
Described positive terminal material is a fine copper, and negative terminal is an aluminium.
The utility model beneficial effect: in performance location and protection double action, pole can be dismantled flexibly.Prevent that to greatest extent the bad utmost point phenomenon of lead contact from taking place, effectively improved battery performance simultaneously, prolong battery useful life; Can guarantee the fail safe of battery.Can simplify assembly technology, operation, reduce the cost of production and product, improve product assembly quality, be fit to large-scale industrial production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of high-capacity lithium-ion power battery pole comprises positive and negative pole 2, and described pole is formed whole by the mounting plate 1 that cylinder and cross section are " T " font, described positive and negative pole is for being superimposed as whole cylinder up and down, and the pole center is provided with internal thread 3.Described positive terminal material is a fine copper, and negative terminal is an aluminium.
In groups or when needing external loading to connect, can perhaps connector directly be designed to double-screw bolt at battery, directly be connected with internal thread with connector directly with the upper end surface of bolt pole.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1, a kind of high-capacity lithium-ion power battery pole, comprise positive and negative pole, it is characterized in that: described pole is formed integral body by the mounting plate that cylinder and cross section are " T " font, and described positive and negative pole is for being superimposed as whole cylinder up and down, and the pole center is provided with internal thread.
