Power brick is the power producer of electric automobile, also is the core component of electric automobile.It is to be combined with multi-form serial or parallel connection by a plurality of cells.Because the electric automobile during traveling operating mode is complicated, can produce more heat transfer in the battery use, internal temperature of battery is raise; Especially the module of a plurality of cells being formed; Temperature in the module can rise sooner, if heat can not in time discharge, can add the inconsistency of macrocell; And the useful life of shortening battery, even cause potential safety hazard.Electric automobile has the characteristic of often quickening with retarded motion simultaneously; And go in different road; These all require the electrokinetic cell bag to have fastness and shock resistance; Therefore when power brick design, the battery cell of forming power brick at first should have heat radiation, reliably, multiple characteristics such as firm and shock resistance.The power brick of present domestic design all is made up of a plurality of battery modules, and forms the battery cell of module, generally adopts the plastic casing packing; Though have advantages such as light weight, low price and resisting salt fog corrosion, its heat dispersion is poor, intensity is not high; Being prone to aging breaking, even causing problem such as power brick internal short-circuit, bringing potential safety hazard to electric motor car; Cause the use cost of power brick to rise simultaneously, economic performance descends, and these all are the bottlenecks of restriction electric automobile development.Therefore, the urgent need design is a kind of in heat radiation, the parallelly connected modular structure of flexible package lithium cell firm and that shock resistance has concurrently.
[summary of the invention]
The purpose of the utility model is to solve the deficiency of prior art, to the characteristics of electric automobile during traveling operating mode, and the flexible packing lithium ion battery own characteristic, a kind of good heat dissipation is provided, and flexible package lithium cell parallel connection modular structure firm and that shock resistance is strong.
For realizing above-mentioned purpose; Design a kind of parallelly connected modular structure based on flexible package lithium cell; Comprise metal top cover (5), metal lower cover (4), plastic insulation piece (3), unit of plastic (2) and battery cell (1); Described metal top cover (5) constitutes assembling with metal lower cover (4) and is connected, and metal top cover (5) and metal lower cover (4) constitute metal shell, it is characterized in that being provided with in the described metal shell two battery cells (1) that parallel connection is range upon range of; Described unit of plastic (2) is arranged at the centre of two battery cell electrodes; Described metal top cover (5) and minor face place, metal lower cover (4) both sides offer groove, and described plastic insulation piece (3) is arranged at the groove of metal top cover (5) and metal lower cover (4) both sides minor face, contact with the flexible packing lithium ion battery packaging shell to prevent the battery cell electrode.
The assembling syndeton that said metal top cover (5) and metal lower cover (4) constitute is mounting hole and waist shape boss assembly structure.
Described metal top cover (5) and metal lower cover (4) adopt aluminium alloy or copper alloy to process.
Adopt heat-conducting glue to fit between described two battery cells and between battery cell and the metal upper and lower cover.
Described unit of plastic (2) and plastic insulation piece (3) adopt the tetrafluoro panel material to process.
The range upon range of battery cell (1) of described two parallel connections is formed a batteries in parallel connection group; The centre of batteries in parallel connection group positive and negative electrode is respectively equipped with two unit of plastics (2); Last piece battery cell electrode hole is corresponding with following piece battery cell electrode hole and unit of plastic screwed hole, adopts bolt to connect.
The utility model compared with prior art, adopt that conductive coefficient is high, intensity preferably material fit with heat-conducting glue between battery cell and the parallelly connected modular structure of battery cell and flexible package lithium cell as flexible package lithium cell parallel connection modular structure.This structure has following advantage:
1. adopt conductive coefficient height, intensity material preferably, the assembly rate of heat dispation is high, can bear certain intensity;
2. adopt metal stamping to form, more firm, durable than plastic material;
3. installation and maintenance is convenient, can reuse, and cost is low.
