The utility model has good heat radiation and ventilation performances, simple structure, high space use rate, light weight, small size, low cost, high safety, and convenient operation, enables a cell assembly structure to be compact, and plays important roles to improve cell performance and to enhance specific energy of the cell.
Description
The utility model is a square sealed cell fastening assembling structure.
Electric motor car is along with the mankind obtain development at full speed to the continuous enhancing of environmental protection consciousness.The exploitation of electric vehicle power battery pack is imperative.As everyone knows, the development of electric motor car is a kind of new and high technology, and the electrokinetic cell that electric motor car uses be in the various applications of battery, require the highest a kind of, battery pack environment for use complexity, variations in temperature is big, and battery pack is installed in the electric motor car, driving process moderately gusty air and vibrations, sharp pounding takes place sometimes, and battery is to work under the condition of impact endurance test shock.Therefore it is big to develop the electric vehicle battery technical difficulty, and to the fail safe of each parts of battery pack, reliability requirement is very high.Battery pack will reach the purpose of practical application, not only will improve the performance of cell, will improve the discharge performance of whole Battery pack simultaneously, and vital here key problem in technology is fail safe and the heat dissipation problem that battery pack is used.
The compound mode of each battery producer square battery is normally made end plate with the thick glass epoxy of 10～15mm at present, separate with the thick glass epoxy of 1～2mm between the cell, the combination of battery is to penetrate in four preformed holes of two end plates with four stay bolts, uses screw, nut that it is fastening then.In this combining structure, four bolts and battery shell wall must leave enough spaces, therefore battery combination takes up room greatly, volumetric specific energy is low, the passage that does not have heat radiation between battery, the heat that battery pack produces in charge and discharge process can't distribute uniformly, and the battery temperature difference is big, directly influences the performance and the life-span of battery.Because the battery assembling fixture is too simple and crude, electric motor car jolts in the process of moving, and cell may the play displacement, cause short circuit and cause danger, thereby poor reliability, fail safe is also poor.
The purpose of this utility model provides a kind of square sealed cell fastening assembling structure, above-mentioned a series of problems that battery exists have been solved when Combination Design, the utlity model has the square sealed cell fastening assembling structure of good heat dissipation ventilation performance, simple in structure, can make the battery composite structure compactness, the space availability ratio height, safe and reliable, perfect heat-dissipating, and easy and simple to handle, to improving battery performance, the specific energy that improves battery plays important effect.
The utility model mainly comprises end plate, and pressing plate and insulating barrier are formed, and battery combination is generally combined by several and tens cells as required.
Below in conjunction with accompanying drawing the utility model is described:
Fig. 1 is the overall schematic of square sealed cell fastening assembling structure.
Fig. 2 is the continuous strip through-hole structure of an insulating barrier schematic diagram.
Fig. 3 is interrupted strip through-hole structure schematic diagram for insulating barrier.
Fig. 4 is the insulating barrier vertical view.
As shown in the figure, 1 is end plate, and 2 is cell, and 3 is insulating barrier, and 4 is pressing plate, and 5 is brace, and 6 is insulating barrier, and 7 is end plate, and 8 is hold-down screw, and 9 is edge, and 10 is gas passage, and 11 is fin.
Be combined as example with ten cells:
Ten cells are put in series, put the hard end plate of material 1,7 at cell head and the tail two ends, between cell, separate with insulating barrier 3, there is edge 9 that battery is fixed on the insulating barrier 3, there is continuous strip through hole the centre or is interrupted strip through hole 10, and fin 11 is arranged, and two adjacent cells can be separated and have through hole 10 to communicate, gas can be free smooth by this passage.The insulating barrier both sides are provided with groove, respectively adhere to two pressing plates 4, with hold-down screw 8 pressing plate 4 are fastened on the fixed position of two end plates in order at last.The sheet made from mesh grid between the cell 5 that is flexible coupling is connected in series, and constitutes complete battery combination frame structure.(seeing accompanying drawing 1).
Characteristics of the present utility model are:
(1) adopts tower structure, its compact conformation, it is little to take up room, cell is assembled in the module after combination, and be limited in certain space, this compressing structure has the effect of pressing in the balancing battery, can reduce the distance between both positive and negative polarity simultaneously, makes the bringing into play of power maximal efficiency of integral battery door.Because combining structure is complete framework, can prevent electric motor car battery play displacement in the vibrations of travelling so in addition, play the antivibration effect, and can prevent short circuit between battery and the conductive connecting piece, cause danger.Battery pack is strengthened fastening with fixation clip, can prevent the cell expansion distortion, and prevents that inside battery utmost point group and the dislocation of parts play from causing battery short circuit.
(2) solved the important technology key issue that the electric vehicle battery group is dispelled the heat.Because the electric vehicle battery group is to be formed by tens or even a hundreds of cell combined serial, together, can battery good heat radiating during battery pack was trooped, and directly influenced the cycle life of battery charging and discharging performance and battery pack.Moreover battery will produce a large amount of heats in working order, reason be battery in charge and discharge process, the polarization heat that cell electrochemical reaction generates, especially under than the large current charge latter stage or the condition of overcharging, the battery heating is particularly serious.When design battery combination anchor clamps, dividing plate adopts special structure, leaves suitable passage between cell for this reason, and electric motor car spontaneous air-flow when operation is taken away the heat energy that battery produced, to reach the purpose of battery cohort heat radiation.
The utlity model has compact conformation, the space availability ratio height helps improving the volume of battery specific energy, has good ventilation and heat performance.To improving the reliability of whole Battery pack, fail safe, quality uniformity, and the cycle life etc. that prolongs whole Battery pack has all played crucial effects.
