Abstract
The utility model discloses a kind of overcurrent protective current carrying lugs for battery module; including current carrying lug ontology; several regularly arranged tab welding pieces are equipped with above the current carrying lug ontology; several heat emission holes are equipped between the tab welding piece; the tab welding piece periphery is equipped with arc groove, and the junction of two free ends of the arc groove is lug striking point.The utility model can be effectively spaced apart being electrically connected for short circuit battery and normal battery, so as to reduce the thermal runaway caused by battery short circuit, play a very good protection when battery occurs short circuit and generates excessive electric current.
Description
Technical field
The utility model is related to the current carrying lug technical fields used in electric vehicle upper battery modules more particularly to one kind to be used for
The overcurrent protective current carrying lug of battery module.
Background technology
As electric vehicle consumer becomes increasingly mature, rationality, electric vehicle has popularized the epoch ridden instead of walk for household,
While trip is convenient and environmental protection, the development of vehicle enterprise also in gradually modular development, Most current batteries of electric automobile packet and
The current carrying lug that battery energy storage device is equipped with, only the common current carrying lug for playing current-carrying, lacks effective special designing to carry
Protection during high battery core short circuit.From the fire accident of domestic and international new-energy automobile as can be seen that battery quality, charging too long,
Vehicle collision etc. can all cause battery internal short-circuit, electric discharge abnormal, so as to cause whole packet thermal runaway.Therefore, it is short to improve battery generation
Protection during road is most important.
Utility model content
The purpose of this utility model is to provide a kind of overcurrent protective current carrying lug for battery module, can be effectively spaced apart short
Road battery is electrically connected with normal battery, so as to reduce the thermal runaway caused by battery short circuit, is played a very good protection.
Technical solution is used by the utility model solves its technical problem：A kind of overcurrent protection for battery module
Type current carrying lug including current carrying lug ontology, is equipped with several regularly arranged tab welding pieces above the current carrying lug ontology, described
Several heat emission holes are equipped between tab welding piece, the tab welding piece periphery is equipped with arc groove, and the two of the arc groove
The junction of a free end is lug striking point.
Further, the arc groove vertically runs through current carrying lug ontology.
Further, several screw holes can be processed according to required on the current carrying lug ontology.
The beneficial effects of the utility model are：The overcurrent protective current carrying lug can be used for the battery pack and electricity of new-energy automobile
Pond energy storage device battery short circuit protection, lug striking point battery occur short circuit generate super-high-current when, because self-resistance compared with
It is big and generate heat, and then cause to fuse, being electrically connected for short circuit battery and normal battery is effectively spaced apart, so as to reduce because battery short circuit draws
The thermal runaway risen, plays a very good protection, causes the situation of battery short circuit because of quality, overshoot, collision, extruding etc. in battery
During generation, battery pack thermal runaway is reduced so as to cause risk on fire for vehicle.
Description of the drawings
Fig. 1 is a kind of structure diagram of overcurrent protective current carrying lug for battery module of the utility model.
Fig. 2 is the enlarged drawing of the utility model A.
In figure：1st, tab welding piece, 2, screw hole, 3, heat emission hole, 4, current carrying lug ontology, 5, lug striking point, 6, arc
Slot.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower all other embodiments obtained, shall fall within the protection scope of the present invention.
Embodiment
A kind of overcurrent protective current carrying lug for battery module, including current carrying lug ontology 4, on the current carrying lug ontology 4
Face is equipped with several regularly arranged tab welding pieces 1, several heat emission holes 3, the pole are equipped between the tab welding piece 1
1 periphery of ear welding piece is equipped with arc groove 6, and the junction of two free ends of the arc groove 6 is lug striking point 5.
Further, the arc groove 6 vertically runs through current carrying lug ontology 4.
Further, several screw holes 2 can be processed according to required on the current carrying lug ontology 4.
When it is implemented, the overcurrent protective current carrying lug is being welded in cylindrical battery module both sides, i.e. battery module just
Pole and cathode position, the overcurrent protective current carrying lug can control the resistance at this, work as battery by the size with battery core junction
When generation short circuit generates excessive electric current, lug striking point 5 can generate heat, and then lug is caused to fuse because self-resistance is larger
5 fusing of point, being electrically connected for short circuit battery and normal battery is effectively separated with this, to ensure the safety of whole packet.
Wherein, screw hole 2 can be used for penetrating the threaded rod of fastening, realize the overcurrent protective current carrying lug and multigroup battery core
Positioning be fastenedly connected.
Wherein, heat emission hole 3 contributes to battery module to radiate.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent character made based on the specification and figures of the utility model or Structural Transformation, are directly or indirectly used in other
Relevant technical field, is equally included in the patent within the scope of the utility model.
