Description
Technical field
The utility model relates to a kind of mining LiFePO4 soft-package battery group that mining equipment uses of supplying with.
Background technology
Mining battery and battery pack mainly are lead-acid battery (groups), Ni-MH battery (group), nickel-cadmium cell (group) and lithium ion battery (group).Along with going deep into of environmental protection and security concepts, except that lithium ion battery (group), other battery and battery pack because exist to pollute, dangerous and capacity is little etc., and the electrical property inferior position will be eliminated gradually.Current mining ferric phosphate lithium cell and battery pack mainly are that the cell with box hat or aluminum hull carries out a large amount of connection in series-parallel, and still there is certain defective in its design.In its use, especially under adverse circumstances, inside battery causes the explosion of battery external shell because a large amount of gas and heat are accumulated in reactions such as physical chemistry, thereby human body is produced serious harm.Meanwhile, because the use of outside batteries housing, battery and battery weight are heavy, and battery and battery pack are exported specific energy, specific power is low.
Summary of the invention
It is good that the technical problem that the utility model will solve provides a kind of fail safe, and capacity is high, the output specific energy, and specific power is high, and mining LiFePO4 soft-package battery group little, in light weight, environmental protection takes up room.
The technical scheme that the utility model adopts is:
A kind of mining LiFePO4 soft-package battery group comprises battery case, is provided with battery cover above the battery case, and binding post is installed on battery cover, in battery case, is provided with electric core group, and the electrode of described electric core group is fixedly connected with binding post through lead; Its special character is: said electric core group is by the electric core element of a plurality of parallel connections, is wrapped in the brown paper and the aluminum plastic film on the electric core element surface that is connected in parallel and be wrapped in the air bag that is positioned at electric core element top in the aluminum plastic film and constitute from inside to outside.
Above-mentioned mining LiFePO4 soft-package battery group, at the middle fuse holder that is provided with the embedded with safety fiber tube of battery cover, described fuse holder is connected between positive terminal and the electric core group.
Above-mentioned mining LiFePO4 soft-package battery group, the arrangement mode of electric core element is in line.
The utility model adopts the mode of the core element combination of monomer electricity and outerwrap brown paper and aluminum plastic film, and in electric core group, reserves air bag, and is fixing to electric core parallel connection well; Saved the space to greatest extent; Effectively utilize the space, and in light weight, and capacity is high; The output specific energy, specific power is high; Greatly reduce battery pack because of under adverse circumstances; Its inside accumulates a large amount of gas owing to reactions such as physical chemistry and heat causes the violent explosion of battery and human body is produced serious harm risk; Reduce because of the inner local excessive pressure of ferric phosphate lithium cell group through air bag, protect the safety of this battery pack and user of service and equipment; Therefore have higher fail safe, reliability.
