Description
Technical field
This utility model relates to lithium battery, specifically a kind of lithium battery for electric vehicle.
Background technology
" lithium battery " is a class by lithium metal or lithium alloy is negative material, the battery using non-aqueous electrolytic solution.
Within 1912, lithium metal battery is proposed by Gilbert N.Lewis the earliest and studies.During 20 century 70,
M.S.Whittingham proposes and begins one's study lithium ion battery.Owing to the chemical characteristic of lithium metal is the most active so that lithium gold
The processing that belongs to, preserve, use, the highest to environmental requirement.So, lithium battery is not the most applied.Along with science and technology
Development, present lithium battery has had become as main flow.
Lithium battery is broadly divided into two classes: lithium metal battery and lithium ion battery.Lithium ion battery does not contains metallic state
Lithium, and can charge.5th generation product lithium metal battery of rechargeable battery was born in 1996, its safety, ratio
Capacity, self-discharge rate and the ratio of performance to price are superior to lithium ion battery.Owing to the high-tech of himself requires to limit, only have now
The company of a few countries is producing this lithium metal battery.
Lithium battery used by electric motor car the most all uses shell to be coated with, and is so possible to prevent battery directly to be hit
Hitting, easily there is, when by bigger shock, the situation that short-circuit fire explodes in existing lithium battery for electric vehicle.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery for electric vehicle, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of lithium battery for electric vehicle, including battery case, is provided with many group battery core assemblies, and electricity in described battery case
Core assembly is connected to a fixed by fixed plate, and the inwall of battery case is provided with the fixing girth sheets of protrusion, and fixed plate is by tight
Fixing bolt is fixing with fixing girth sheets to be connected；The inside bottom of described battery case is provided with asbestos cloth, utilizes asbestos cloth to realize resistance
Combustion and buffering；The positive terminal in mating connection with battery core assembly and anode connector, and institute are installed on described battery case
The sidewall stating battery case is provided with an insulating oil interpolation mouth, and the inner side of battery case is injected with insulating oil, utilizes insulating oil real
The cooling of existing battery core assembly, insulating oil can avoid battery core assembly the situation of short circuit burning occur simultaneously.
As further program of the utility model: the bottom of described battery case is provided with at leakage fluid dram, and leakage fluid dram pacifies
Equipped with sealing-plug.
As this utility model further scheme: described battery case uses engineering plastics to make, and bulk strength is high,
The lightest.
Compared with prior art, the beneficial effects of the utility model are: this utility model utilizes the insulating oil can be effectively
Time in prevent lithium battery from the situation of short-circuit fire occurring, the most just can effectively prevent shock from bringing blast, thus overall
The safest.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lithium battery for electric vehicle of this utility model.
In figure: 1-battery case, 2-battery core assembly, 3-fixed plate, 4-positive terminal, 5-anode connector, 6-fix girth sheets,
7-fastening bolt, 8-insulating oil add mouth, 10-sealing-plug.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of lithium battery for electric vehicle, including battery case 1, described electricity
Many group battery core assemblies 2 are installed in pond shell 1, and battery core assembly 2 is connected to a fixed by fixed plate 3, the inwall of battery case 1
On the fixing girth sheets 6 of protrusion is installed, fixed plate 3 is fixed with fixing girth sheets 6 by fastening bolt 7 and is connected；Described battery case 1
Inside bottom asbestos cloth is installed, utilize asbestos cloth realize fire-retardant and buffering；It is provided with and battery core on described battery case 1
Positive terminal 4 that assembly 2 is in mating connection and anode connector 5, and the sidewall of described battery case 1 is provided with an insulating oil and adds
Mouth 8, the inner side of battery case 1 is injected with insulating oil, utilizes insulating oil to realize the cooling of battery core assembly 2, and insulating oil is permissible simultaneously
Avoid battery core assembly that the situation of short circuit burning occurs.
The bottom of described battery case 1 is provided with at leakage fluid dram, and leakage fluid dram and is provided with sealing-plug 10.
Described battery case 1 uses engineering plastics to make, and bulk strength is high, the lightest.
Operation principle of the present utility model is: the sidewall of battery case 1 is provided with an insulating oil and adds mouth 8, battery case 1
Inner side be injected with insulating oil, utilize insulating oil to realize the cooling of battery core assembly 2, insulating oil can avoid battery core assembly to go out simultaneously
The situation of existing short circuit burning.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
