Background technology
Due to lithium battery have that volume is little, discharge voltage is stable, operating temperature range width, self-discharge rate are low, length storage life, memory-less effect, the advantage such as lightweight and nuisanceless, the most gradually substitute lead-acid accumulator, cadmium-nickel accumulator at present, be widely used in various occasion.
But the battery core in current battery group is usually and uses conventional nickel sheet to connect, and the voltage of the position connecing protection board in the electric current path through flowing through near set of cells output is relatively big, so that temperature is higher and then shadow noon battery core temperature, causes shorter battery life；When that occurs, lithium ion battery pressure rolls up with heat, easily produces spark, burns and even explode, has the biggest potential safety hazard.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes one and there is uniform current distributed architecture Li-ion batteries piles, the structure of existing connection nickel sheet is improved, make connection nickel sheet can change current direction and increase sectional area, prevent the generation of the potential safety hazard mentioned in background technology, and then solve the deficiency of prior art.
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that, one has uniform current distributed architecture Li-ion batteries piles, including multiple monomer battery cores, realizes connection in series-parallel by an attachment structure and connect between monomer battery core；This attachment structure includes that multiple holders that support and array are located in support, support and holder connect by nickel sheet is fixing, fixes in monomer battery core is placed in this holder, and the negative pole of monomer battery core contacts with this holder；In attachment structure, the side of its support stretches out, and forms multiple contact, and each contact is electrically connected with by an electric-conductor.This attachment structure achieves the connection in series-parallel of multiple monomer battery core and connects, and the setting of electric-conductor thereon makes current direction and structure change, and makes the electric current in attachment structure uniformly derive, it is achieved temperature reduces, and circuit sectional area increases, and improves the safety of set of cells.
Further, for ease of making, as a feasible scheme, the structure of each contact is identical, and the length range of contact is preferably 10-15mm, and the width range of contact is preferably 5-10mm, and the spacing of adjacent pads is preferably 15-42mm.
Further, as a feasible scheme, described electric-conductor uses copper bar to realize, it is preferred that the thickness range of this copper bar is that 0.5-2mm is thick.
Further, as a feasible scheme, described holder has an end face, and end face downwardly extends and be provided with multiple shell fragment, and multiple shell fragments form a grasping part to clamp monomer battery core；Support has a smooth bottom surface, and the end face of holder contacts connection with the underrun nickel sheet of this support.
This utility model is by setting up attachment structure, and arranges electric-conductor in attachment structure, makes current direction and structure change, the electric current in attachment structure is made uniformly to derive, and then realizing temperature reduction, circuit sectional area increases simultaneously, thus improves the safety of set of cells.This utility model is skillfully constructed, simple in construction, and is easily achieved, and has good practicality.
