Description
[technical field]
The present invention relates to cell safety and use technical field, concrete, it provides a kind of high security battery system.
[background technology]
Battery, for article the most common in daily life, it is for being powered to other equipment.
Battery can form battery system and use, but during it uses, owing to using environment not mate or operate the reasons such as lack of standardization, the blast of trigger monomer battery;
Cell explosion time temperature in atmosphere is the highest, more than instantaneous temperature to 750 DEG C, and then relevant device or adjacent battery is produced impact;
As, use the battery system being made up of multiple cells, when the cell generation explosion accident of one of them, its periphery instantaneous temperature is to more than 750 DEG C, and the cell of periphery the most also occurs the chain reactions such as blast, causes the expansion of accident.
It is therefore desirable to provide a kind of high security battery system to solve the problems referred to above.
[summary of the invention]
Present invention is primarily targeted at a kind of high security battery system of offer, it can make cell dispel the heat rapidly after exploding, cause chain reaction after avoiding battery explosion simultaneously, improves the use safety coefficient of battery.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of high security battery system, including:
Battery main body;
Battery case;
Conduction oil;
It is positioned in described Battery case after described battery main body is connected external cabling, and in described Battery case, injects described conduction oil.
Further, described battery main body is cell or the some battery modules being made up of some cells.
Further, described conduction oil injection rate is at least to flood described battery main body.
Further, described conduction oil is high-flash heat conductive insulating oil.
Compared with prior art, a kind of high security battery system of the present invention, it can make cell dispel the heat rapidly after exploding, cause chain reaction after avoiding battery explosion simultaneously, improves the use safety coefficient of battery.
[accompanying drawing explanation]
Fig. 1 is 26800YL-5.6Ah cell temperature schematic diagram after the ignition under different medium in embodiments of the invention 1;
Fig. 2 is the distribution schematic diagram of battery modules in embodiment 2;
Fig. 3 is each relevant position temperature schematic diagram after 26800YL-5.6Ah cell is ignited in Fig. 2;
[detailed description of the invention]
Embodiment 1:
Refer to Fig. 1, the temperature acquisition after the present embodiment provides a kind of 26800YL-5.6Ah cell to ignite under different medium is tested, and experimental procedure is as follows:
1) put into after 26800YL-5.6Ah cell being connected temperature probe and firing switch in Battery case and seal;
2a) 26800YL-5.6Ah cell is directly ignited, and record relevant temperature;
2b) inject in Battery case and flood the 1# conduction oil of 26800YL-5.6Ah cell, after 26800YL-5.6Ah cell is directly ignited, and record relevant temperature;
2c) inject in Battery case and flood the 2# conduction oil of 26800YL-5.6Ah cell, after 26800YL-5.6Ah cell is directly ignited, and record relevant temperature;
3) contrast step 2a), step 2b), step 2c) and conclude that 26800YL-5.6Ah cell the most directly explodes, 26800YL-5.6Ah cell instantaneous temperature is to more than 750 DEG C;Exploding in conduction oil, its temperature is increased to about 400 DEG C, and temperature approach is at about 350 DEG C, and the coefficient of utilization of battery is greatly improved.
Wherein:
Conduction oil can directly use high-flash heat conductive insulating oil best results.
Embodiment 2:
Refer to Fig. 2, Fig. 3, a kind of 9 battery modules being made up of 14 26800YL-5.6Ah cells of the present embodiment offer are uniformly arranged after being placed in conduction oil, temperature acquisition experiment at each battery modules after the ignition of single 26800YL-5.6Ah cell, experimental procedure is as follows:
1) refer to Fig. 2, the arrangement of 14 26800YL-5.6Ah cells is constituted battery modules, and arrange after 9 battery modules are uniformly arranged;On No. 5 modules, set labelling ignite battery (the 26800YL-5.6Ah cell heavy label ignites battery as labelling) and connect firing switch, and labelling is ignited 6 26800YL-5.6Ah cells of battery circumferential and put in Battery case as after connecting corresponding Omron temperature probe behind temperature test district;
2) in Battery case filling heat-conductive oil, conduction oil floods battery modules, after Battery case is sealed;
3) ignite labelling and ignite battery, and record the temperature of relevant position;
4) by step 3) draw data, it could be assumed that, battery modules is under being immersed in conduction oil occasion, when 26800YL-5.6Ah cell explodes, its peripheral temperature is held in less than 350 °, i.e. 26800YL-5.6Ah cell generation blast will not cause chain reaction.
Wherein:
Conduction oil can directly use high-flash heat conductive insulating oil best results.
In conjunction with the embodiments 1 and embodiment 2, it may be concluded that conduction oil can play good heat-conducting effect as medium, battery safety in conduction oil is preferable, and cell blast will not cause chain reaction, and temperature increase also reduces, and safety is greatly promoted.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.
