Description
Technical field
The present invention relates to a kind of battery module, specifically, relate to and a kind ofly can hold the next door in fixing installation site, and can improve the battery module of the adhesion of element cell in the housing.
Background technology
Generally speaking, the secondary cell rechargeable also can use repeatedly.Particularly, the secondary cell that includes only a monocell (battery cell) is mainly used in various small portable electronic device, as is used for cell phone, laptop computer, camera and takes the photograph video recorder.The secondary cell of high power capacity (below be referred to as ' battery module ') is formed by connecting by a plurality of monocells { below be referred to as ' element cell ' (unit batteries) }, and it is mainly as the power supply of drive motors, as, as driving fuel oil electric power convertible car (HEV
S), electric motor car (EV
S) power supply that waits.
Each element cell that constitutes battery module comprises: have positive plate, negative plate and be arranged on the electrode assemblie that positive/negative plate is used as the dividing plate of insulator between the two; Housing with space of hold electrodes assembly; Combine the also cap assemblies of deadend housing with housing; And the positive terminal and the negative terminal that protrude and be electrically connected with positive plate and negative plate respectively from cap assemblies.
In addition, when each element cell is the prismatic batteries of routine, the positive terminal of the positive terminal of an element cell that will protrude up from cap assemblies and negative terminal is arranged so that another element cell adjacent with this element cell and negative terminal are alternately, between threaded positive pole and negative terminal, connect by conductor, so that nut is fixed thereon, thereby form battery module.
In view of being connected to each other by several or tens element cells, battery module forms, because being whole volumes, the cooling structure that conventional battery module need be able to distribute the heat that produces in each element cell easily, release mechanism, circuit system etc., the problem that this battery module exists strengthen.
In order to solve described problem, adopted by reducing the method that interval between element cell reduces the size of battery module, but another problem that thereupon produces is to be difficult to the heat that produces in the element cell is distributed.
Therefore, for battery module design, need a kind of structure that can easily the heat that produces in each element cell be distributed and can reduce the battery module volume.If the heat that produces in each element cell can not distribute effectively, its temperature will raise, and the result causes using the device fails of this battery module.
In particular, be used for HEV
S, EV
SDeng height output and the high-capacity battery module in heat is distributed is all in all.If strengthen the size of battery module, the problem of existence is, not only the weight of battery module increases, and the design of the equipment (especially vehicle) that assembles with battery module also will become complicated.
Therefore, in modern batteries practice, possess in the battery module of high output and high power capacity requiring, developing the size minimum, to improve the battery module of heat distribution performance again significant.
And, in traditional battery module, between each element cell, be provided with the space that is used for cooling air circulation.The next door is installed in case the distortion of stop element battery structure.Opposite end at battery module is equipped with end plate.Utilize elongated restriction rod fixed charge method end plate to come support unit battery and next door.
Yet, the problem that this traditional battery module exists is, when applying external force, uneven distortion may take place in the battery module, this will reduce the reliability of battery module, cause the installation site (interval between the next door) that is difficult to the next door to remain unchanged, and be difficult to prevent the shift in position of element cell.
Summary of the invention
The purpose of this invention is to provide a kind of battery module, form as one, make the installation site in next door constant, and make the distortion of next door and housing even by the next door is securely fixed in the housing or with next door and housing.
Another object of the present invention provides a kind of battery module, improves between housing and the element cell or the adhesion between housing and the next door by forming battery fixing structure, and prevents battery pack (batteryunit) position change.
For achieving the above object, provide a kind of battery module, it comprises: housing, and it has a pair of opposed side plate, a pair of opposed supporting bracket and at least one open surface; In described housing with the hard-wired a plurality of next doors of predetermined space; And can insert a plurality of element cells in the described housing by described at least one open surface, wherein, adjacent-cell battery is separated each other by a next door, and wherein, described battery module also comprises: at the standing part of described at least one open surface from an edge protrusion of each described opposed supporting bracket; The standing part that reaches two opposed supporting brackets is connected to the fixed lever that supports each other.
