Description
Technical field
The utility model relates to field of batteries, relates in particular to a kind of cell module for battery pack.
Background technology
Lithium titanate lithium ion battery, as a kind of desirable environmental protection power supply, has the advantages such as specific capacity is high, operating voltage is high, temperature limit is wide, have extended cycle life, security performance is good, has been widely used at present every field.Along with the development of field of traffic technology, the lithium titanate lithium ion battery of the large electric current of track traffic (comprising subway, high ferro etc.) needs, high power charging-discharging; Consider from security standpoint, two electrodes of this battery should design on two end faces of battery.In application, usually need to use the battery pack forming after several this battery strings combination, and cell module is the critical component of battery pack.
Current cell module product, only, for the array being made up of at multiple cells of the same end face of battery positive and negative electrode, designs the fixtures such as supporting bracket and fixes, protects battery; And when existing cell module to be given a shock or pushing, the hard contact of battery and supporting bracket easily cause snap being connected between battery container breakage, battery, become flexible, the problem such as fracture.And for the cell module and the battery pack thereof that are formed at multiple cells at battery two ends by positive and negative electrode, there is no practical fixed structure.Therefore, for the array being made up of at multiple cells at battery two ends positive and negative electrode, how first designing a kind of compact conformation, fixation and have the cell module of the fixed structure of anti-vibration extruding, is the problem that industry is paid close attention to.
Utility model content
Main purpose of the present utility model is the multiple cells at battery two ends for positive and negative electrode, and a kind of cell module for battery pack is provided; And implementation structure compactness, fixation there is the effect of anti-vibration extruding.
The utility model solves the technical scheme that its technical problem adopts:
A kind of cell module for battery pack, it is characterized in that, comprise the array that divides the cell that is located at two ends to form with the contrary assembled arrangement of adjacent cell polarity by some positive and negative electrodes, the positive and negative electrode of adjacent cell connects by brace, end face and bottom surface at described array are respectively equipped with upper and lower supporting seat, the groove at the packed battery two ends of can crouching is set respectively on described upper and lower supporting seat, the intercommunicating pore that can expose battery electrode is set between interconnective battery grooves, and described upper and lower supporting seat is fixedly connected with by many support columns.
In the groove floor of described upper and lower supporting seat respectively and elastic buffer rubber cushion is set between battery upper and lower end face.
Being shaped as of described elastic buffer rubber cushion is circular.
The material of described elastic buffer rubber cushion is EPDM.
On described brace, attach insulating heat-conductive adhesive tape.
The beneficial effects of the utility model are: the groove at the packed battery two ends of can crouching is set respectively on upper and lower supporting seat, effectively self-contained battery; And, upper and lower supporting seat couples together by support column, both can make the bulk strength reliability of cell module increase, can effectively limit again the position of each battery, prevent that battery from use vibrating with respect to module, cause to connect to snap with battery and damage, effectively prevent because the cell module battery that unbalance stress causes in the time assembling damages.The intercommunicating pore that can expose battery the two poles of the earth arranging on upper and lower supporting seat, is convenient to arrange brace, and the position of adjusting intercommunicating pore can change the series-parallel system of array.In the groove floor of upper and lower supporting seat respectively and the elastic buffer rubber cushion arranging between battery upper and lower end face, in the time that cell module is given a shock or push, can effectively prevent that battery from contacting firmly with supporting seat, play buffering, dividing potential drop effect, can effectively prevent battery container breakage that vibrations cause, effectively prevent cell module structure in use procedure connect snap, become flexible, the situation such as fracture.Between the positive and negative electrode of each cell, connect by brace, on brace, adhere to insulating heat-conductive adhesive tape, be conducive to battery heat radiation.Compared with prior art, the utility model provides a kind of cell module of the battery pack forming at multiple cells at battery two ends for positive and negative electrode, its compact conformation, reliability are high, effectively anti-vibration extruding, are applicable to develop all kinds of standard modules, are suitable in industry and promote.
