Abstract
A monomer battery structure for a lithium battery pack comprises an aluminum box and a battery core in the aluminum box, wherein two sides of the battery core are respectively provided with a heat conduction silica gel; one side of the heat conduction silica gel is stuck on outer surface of the battery core; and the other side is stuck on the inner surface of the aluminum box. The utility model belongs to the field of power supply of a motor-driven car and provides a monomer battery structure for a lithium battery pack which can prevent puncture and leakage, has excellent radiating property and prolongs the long service life.
Description
Technical field:
The utility model relates to the electric vehicle power supply, particularly the cell structure of electric vehicle lithium battery group.
Background technology:
Satisfy the requirement of electric motor car to power supply capacity for increasing battery capacity, general way is with the more piece single lithium battery and is unified into battery pack at present.Existing single lithium battery is made up of aluminum hull and the battery that is installed in the aluminum hull mostly, and the shortcoming of this structure is: 1, the some contact that brings of battery air spots causes the thermal resistance increase easily, influences radiating effect; 2, insulation property are not good, occur the phenomenon that shell is passed in the battery electric leakage easily; 3, the burr on aluminum hull surface might be stabbed battery; 4, the shell wall of aluminum hull has limited the aging expansion space of battery to a certain extent, and then has shortened the useful life of battery.
The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of prevent stabbing with anticreep, thermal diffusivity good and the cell structure of the lithium battery group that can increase the service life.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of cell structure of lithium battery group comprises the aluminium box and is installed in the interior battery of aluminium box that the both sides of described battery are respectively equipped with a slice heat conductive silica gel, and described heat conductive silica gel simultaneously is affixed on the outer surface of battery, and another side is affixed on the inner surface of aluminium box.
Described aluminium box is spirally connected by two blocks of aluminium sheets that are provided with flanging and forms, wherein be fixed with outward extending threaded on the flanging of an aluminium sheet, the flanging of another piece aluminium sheet is wrapped in the last flanging outside, and have the pin-and-hole that passes for described threaded on the flanging outside this is wrapped in, described two flangings are by being spun on the nut locking of threaded outer end.
The outer surface of described two heat conductive silica gels is affixed on the inner surface of two blocks of aluminium sheets respectively.
Be equipped with flanging around the described aluminium sheet.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
1, all stick heat conductive silica gel in the both sides of battery, the thermal resistance that causes increases phenomenon to avoid the some contact that the battery air spots brings, and makes its good heat dissipation effect.
2, between battery and aluminium box, heat conductive silica gel is set, can stay the expansion space in advance for the aging expansion of battery, prolong the working life of battery.
3, heat conductive silica gel has the excellent electric insulating energy, can prevent battery electric leakage to pass to shell, and simultaneously, an amount of hardness of heat conductive silica gel can also prevent that aluminium box burr from stabbing battery.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, the cell structure of the lithium battery group that provides according to the utility model comprises aluminium box 1 and is installed in battery 2 in the aluminium box 1 that the both sides of battery 2 are respectively equipped with a slice heat conductive silica gel 3, heat conductive silica gel 3 one sides are affixed on the outer surface of battery 2, and another side is affixed on the inner surface of aluminium box 1.Aluminium box 1 is spirally connected by the aluminium sheet 11,12 that is equipped with flanging 111,121 around two and forms, installing/dismounting is all very simple, concrete spiro connection structure is: wherein be fixed with outward extending threaded 113 on the flanging 111 of an aluminium sheet 11, the flanging 121 of another piece aluminium sheet 12 is wrapped in last flanging 111 outsides, and have nut 115 lockings of pin-and-hole 114, two flangings 111,121 by being spun on threaded 113 outer ends of passing on the flanging 121 outside this is wrapped in for threaded 113.In addition, furthermore, the outer surface of two heat conductive silica gels 3 is affixed on the inner surface of two blocks of aluminium sheets 11,12 respectively.
