At present, aluminum hull rectangular cell cover plate is substantially without anti-overcharge structure, and the anti-overcharge means of battery mostly are interpolation electrolysis additive or select safer LFP material as cell positive material, and energy efficiency is the highest.
Along with the development of ternary, occurring in that some anti-overcharge cover plates, principle are mainly short-circuit structure at present, do not block electric current completely, there is hidden danger in cell safety, separately these a little structures, and demand space is relatively big, and cost of manufacture and process are complicated.
Utility model content
In order to solve use safety problem and the problem of over-charging of battery safety of square aluminum-shell battery, this utility model provides a kind of can rush battery cover board by the anti-mistake of cell circuit failure of current, is greatly improved the security performance of battery and anti-overcharge ability.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of anti-mistake rushes battery cover board, including the battery core cover plate main body being stacked up and down and bottom insulation board, and it is arranged on positive terminal and the negative terminal of these battery core cover plate main body both sides, described positive terminal includes on the positive pole that is sequentially stacked conducting strip under conducting strip, positive pole insulation board and positive pole, being turned on by rupture disk between conducting strip under conducting strip and positive pole on described positive pole, this rupture disk can disconnect conducting strip and the connection of conducting strip under positive pole on positive pole when cell internal pressure is excessive.
Further, described rupture disk includes the positive pole guide pillar body running through described positive pole insulation board, and the top of this positive pole guide pillar body is connected with conducting strip on described positive pole by the thin slice of both sides, and the bottom of positive pole guide pillar body connects with conducting strip under described positive pole.
Further, described negative terminal includes on the negative pole that is sequentially stacked conducting strip under conducting strip, negative insulation plate and negative pole, and for connecting the negative pole guide pillar body of the upper and lower conducting strip of negative pole.
Further, described battery core cover plate main body offers explosion-proof valve.
From above technical scheme, this utility model, compared with short circuit battery cover plate, has the advantages that
(1), when over-charging of battery or exception, it is internally formed open circuit, blocks electric current completely, can guarantee that the safety of battery；
(2) battery core is without adding anti-overcharge additive, and battery performance is good；
(3) rupture disk is integrated in inside positive terminal, saves space；
(4) simple in construction, it is simple to production and processing；
(5) battery that this cover plate produces pack in groups time carry cut-off loop because of each battery, the safety of whole battery bag is high.
