Description
Technical field
The plumbous lithium battery of long-acting big capacity belongs to secondary accumulator battery and makes the field, is specifically related to the plumbous lithium battery of long-acting big capacity of a kind of flexible packing lithium ion battery assembling in parallel, and it is mainly used in submarine underwater engine and large-scale energy-accumulating power station in the defence equipment.
Background technology
Flexible package lithium cell mainly comprises aluminum plastic film flexible package lithium cell and special-shaped flexible package lithium cell.At present flexible packing lithium ion battery welds after adopting the lug mutual superposition of mode with each battery Soft Roll of parallel connection or series connection more, utilizes means such as battery case to pack, reinforce after assembling again, so that the safe handling down of various again environment.For capacity and the cruising time that increases battery pack, mainly assemble by the mode of parallel connection.For large-capacity battery, once Bing Lian battery unit is generally at tens to tens, for guaranteeing that battery performance must make the temperature difference between the battery unit minimize, promptly how to arrange regardless of the position of battery unit, effectively dissipated from the caloric requirement that battery unit produces, otherwise the temperature difference that produces between battery unit can reduce the charge/discharge life-span of storage battery, reduces battery performance, and serious temperature is too high even can set off an explosion.
In addition, after the soft-package battery unit uses in groups, if have the performance of the electric core of a soft-package battery unit there are differences or can not normally use, can directly have influence on the use of other soft-package battery unit in the storage battery, cause a large amount of losses and the wasting of resources, the mass that has a strong impact on the Soft Roll lithium battery uses, and increases use cost.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of dissipation of heat performance good, the plumbous lithium battery of the long-acting big capacity that not influenced by the damage of single battery unit.
The technical scheme that its technical problem that solves the utility model adopts is: the plumbous lithium battery of this long-acting big capacity, comprise positive pole, negative pole, positive bus, negative bus, a plurality of battery Soft Roll, coldplate and battery container, positive and negative electrode protrudes in battery container, and be connected with positive negative bus by lead respectively, it is characterized in that: a plurality of battery Soft Rolls two ends are installed in parallel between positive and negative bus-bar by lead respectively, lead is provided with protector, is interval with coldplate between the battery Soft Roll.
Described coldplate is a stereotype, and inside is arranged with many cooling water pipes in parallel, and the cooling water pipe entery and delivery port stretches out battery container, and the cooling water pipe import is connected with cooling water tank by circulating water pump.
Described coldplate is a multilayer, and " bow " font is circuitous to be arranged in the battery container, and each interlayer is every being arranged between each pond Soft Roll.
Described a plurality of battery Soft Rolls two ends respectively by wire bonds between positive and negative bus-bar.
Described battery Soft Roll is lithium ion battery Soft Roll or lead acid accumulator Soft Roll.
Compared with prior art, the beneficial effect that the plumbous lithium battery of the long-acting big capacity of the utility model is had is: 1, by on the lead of battery Soft Roll two ends protector being set respectively, effectively overcome the shortcoming that the single Soft Roll of traditional Soft Roll storage battery is scrapped the whole battery applications of influence.2, between each battery Soft Roll, at interval coldplate is set, has improved the dissipation of heat performance of battery, guarantee to use when battery is long; Add cooling water pipe in the coldplate, reach favorable cooling effect by boiler water circulation.3, owing to solved many Battery packs Soft Roll heat dissipation problem that uses in parallel, can realize the parallel connection of any many Battery packs Soft Roll, increase substantially battery capacity, long-acting large-capacity battery in the time of can preparing 1～100 Wan An as required.4, adopt stereotype as coldplate, can realize the requirement of battery counterweight simultaneously, the traditional large-scale lead acid accumulator of convenient directly replacement satisfies underwater work system such as submarine to the counterweight requirement.5, the plumbous lithium battery structure of this long-acting big capacity is simple, easy to make, compares with traditional storage battery, and can prolong twice useful life.6, plumbic acid cell heap(ed) capacity is less than 10000Ah at present, and every weight reaches 1 ton, and the plumbous lithium battery capacity of same weight can reach 30000Ah, and internal resistance is lower, and cycle life is longer, and existing lead-acid battery manufacturing process can directly be utilized.
