To solve the radiation problem in static or working conditions, the utility model adopts metal tubes to radiate heat, which makes natural wind pass through the metal tubes between each cell monomer and effectively and rapidly decreases the temperature.
Description
Affiliated technical field
The utility model relates to a kind of high-power polymer Li-ion power assembled battery and cooling combining structure thereof.
Background technology
At present, high-power voltage lithium ion battery is the version that adopts liquid duricrust sealing, liquid duricrust sealing lithium ion battery is solving the technical barrier that there is key in aspects such as blast protection, heat radiation, control change in voltage, adopt general polymer architecture form to run into again can't to realize high-power, the in parallel or series connection of many monomers of present technique has solved the difficult problem of this respect.
Summary of the invention
Adopt the combining structure of the in parallel or series connection of the sub-battery of a plurality of monomer flexible-packaged lithiums for the power problem that overcomes existing monomer lithium ion battery.For overcoming the heat radiation under a plurality of lithium ion battery work or the inactive state and the technical barrier of cooling; adopted at the place ahead and the place, rear of shell and be drilled with some apertures; in the middle of each monomer, place metal side tube or the pipe of hollow or the metallic plate of hollow of hollow; and install fan in battery pack inside; between battery, put temperature probe; control fan by the temperature controller that is arranged in the protection circuit, this compound mode reaches rapid cooling and cooling purpose.
The technical scheme that its technical problem that solves the utility model adopts is: present flexible packing lithium ion battery is that monomer uses, and does not have the lithium ion battery of high-power or super high power.For the power problem that overcomes existing monomer lithium ion battery adopts the combining structure of the in parallel or series connection of a plurality of monomer flexible packing lithium ion batteries, but can make the heat dissipation problem of battery become key like this.For overcoming the heat radiation under the static or operating state of a plurality of lithium ions and the technical barrier of cooling; adopted at the place ahead and the place, rear of shell and be drilled with some apertures; in the middle of each monomer, place metal side tube or the pipe of hollow or the metallic plate of hollow of hollow; and install fan in battery pack inside; between battery, put temperature probe; control fan by the temperature inductor that is arranged in the protection circuit, this compound mode reaches rapid cooling and cooling purpose.
The course of work of this high-power lithium ion battery with cooling technology is: the utility model relates to a kind of high-power power assembled battery pond and cooling combining structure thereof, and it makes every several flexible packing lithium ion cells in addition in parallel or connect and make up with metallic conductor, again the combination of parallel connection or series system is carried out in each such Battery pack combination again, thereby reached the purpose of high-power or super high power.But after in parallel or series connection, can produce certain temperature; for the technical barrier that solves its heat radiation and ventilate is put into some square tubes or pipe between each monomer; metal tube is cross ventilation; correspondingly at the shell the place ahead of entire cell combination and rear be drilled with some apertures with the metal tube between monomer; and install fan in battery pack inside; control fan by the temperature inductor that is arranged in the protection circuit; in order to passing through smoothly without barrier of air outside, thereby reach heat radiation and the purpose of lowering the temperature.
The beneficial effects of the utility model are: 1, lithium ion battery can be realized high-power, 2, solve heat dissipation problem effectively, 3, can realize lithium ion battery is carried out the variation combination of the multivoltage of 3.6V multiple, leave out when 4, individual cell breaks down and to realize emergentization subsequently, 5, can realize that battery failures reviews one's lessons by oneself eliminating.
